How to Fix Your Slow Internet

Expert tips to banish slow internet speeds

You can generally fix a slow internet connection if the issue is on your end. A simple restart of your modem and your router (or all-in-one wireless gateway) can sometimes speed up your connection. But your slow speeds may also be the result of problems on your provider’s end—problems you just can’t fix.

Generally, your modem or router (or both) will create a speed bottleneck if not working properly—the same goes with wireless gateways. If your equipment is too old, it may not support important internet protocols. Equipment damage, such as bad ports or components, can also cause slowdowns.

There are a few ways to make sure each step of your network is performing at optimal speed. We’ll help you identify and fix your network’s weakest link starting with the basics—we’ll get more in-depth as we go deeper into our guide.

Why is your internet so slow?

There are many reasons why your internet is slow. Perhaps your internet provider is having issues, your home network needs a reboot, or you’re just too far away from the router—the possibilities can be a bit overwhelming. We’ll list the most common problems and how you can fix them to get more speed.

 

Problem: Your internet plan is too slow

If your internet slows down only when too many other people are online simultaneously, you’re probably using more bandwidth than your plan allows. Use our internet speed test to see if you’re getting the speed advertised by your ISP. If your results are close to your plan speed, consider upgrading.

Your internet package gives you a specific amount of bandwidth, and if there’s more information trying to move around than there is bandwidth, you run into a traffic jam. 

Think of your internet connection like a road directly to your house. One car’s worth of people (or internet data) can reach your house at a time. If there are three cars trying to get there, they have to line up to get to your house. And if more cars arrive as the others are waiting to reach your house, the line and the delays get longer. 

The easiest way to get more bandwidth is by upgrading to a faster internet plan that can keep up with your household. We’re online now more than ever, and the internet plan you signed up for a few years ago might not be sufficient today if your connection slows down every time multiple people use the internet.

Problem: You need better network management

If upgrading isn’t an option, you need to either deal with the slow speeds or manage your household’s internet use. Thankfully, there are several easy ways of doing the latter that doesn’t include yelling at everyone to get off the internet so you can attend a Zoom meeting.

Here are a few tips on how to manage your home network traffic:

Use QoS settings

Many routers have a quality of service (or QoS) component that allows you to control how your network prioritizes certain types of data. That way, you can make sure your streaming data always gets first access to available bandwidth for smooth playback.

Not all routers have adjustable QoS, but if your router does, you’ll find the controls in your router’s web interface.

Pro tip: How to log in to a router

Many of our tips and troubleshooting guides tell you to log in to your router’s web interface. It’s really easy if you don’t know how—just follow our instructions.

Prune your internet connections

There may be some devices connected to your network that you rarely use—if at all. For example: you bought a new laptop, but the old one still idles and connects to the network. Even though it’s not in use, it still uses bandwidth for updates and other background services. Your router may even have a limited number of devices it can connect to simultaneously, and if you have too many connected devices the router may start kicking some of them off the network. 

One simple way to take stock of all the devices using your network is to load your router’s web interface and view the network map. You will see all connected devices, whether they’re active or not, so you can block the ones you never use.

Another method is to change the Wi-Fi password, but that only applies to wireless devices. Once you do, you must manually reconnect every device that accesses your wireless network

Some routers or wireless gateways also have a handy companion app that lets you see everything on your network without loading a browser. That way you can identify and remove devices that no longer need access to your network.

Stagger bandwidth-hogging activities

If your connection can’t handle everyone online at once, stagger your internet activities so everyone gets a chance at an uninterrupted connection.

Also, make sure to schedule big downloads (like computer and game updates) during times when other people won’t be online.

Put visitors on a guest network

There’s nothing wrong with sharing your internet with guests when they come to visit, but you don’t want them to secretly download illegal content while they lounge on your couch. That’s where your router’s guest network feature comes into play.

You can create a second guest network using your router’s web interface or mobile app. A guest network allows you to limit how much bandwidth guests can use, and what services and websites they can access. It also provides improved security by preventing guests’ devices from mingling with your devices, so there’s no worry about guests spreading malware to everything you use.

Pro tip:

Our guide on how to set up guest Wi-Fi covers a few different ways to establish a second network.

Problem: Your provider’s network is congested

Cable internet subscribers may suffer slowdowns during peak times when they and everyone else in the neighborhood are active online at the same time. It’s a similar situation to traffic on your home network but on a larger scale. In this instance, you and all your neighbors compete for the same bandwidth.

If the congestion gets particularly bad, your internet provider may throttle internet speeds in your area to reduce traffic for the network.

Unfortunately, you can’t control when or how often people in the same area use the internet—we certainly don’t advise asking your neighbors to log off so you can Zoom in peace. But there are a few tricks to circumventing the issue.

Try to schedule game and media downloads during off-peak hours, like in the middle of the night. You could also switch to another provider that doesn’t have as many subscribers around you, though that could be difficult to determine.

On the bright side, because cable ISPs have been adding a lot more neighborhood nodes to their networks, neighborhood-level congestion isn’t as big of a problem as it used to be.

The only type of internet that isn’t much affected by an area’s network congestion is fiber internet. Fiber infrastructure is capable of carrying much more information than other internet types, so having a ton of traffic at the same time doesn’t slow down individual customers.

Problem: You exceeded your data cap

Many internet providers have data caps, and some slow your speeds to a crawl after you hit that cap. You can usually check to see how much data you’ve used on your online account or through your ISP’s app. Providers like Xfinity give customers very high data caps—1.2 TB for this example—and shouldn’t cause too many issues for most households. But satellite internet providers including HughesNet and Viasat are less generous with their data allowances.

Satellite internet providers charge for internet use by data rather than by internet speed. It’s similar to how cell phone plans usually work: once you use up your data allowance for the month, your internet connection can slow to a crawl. 

HughesNet customers can see speeds drop to 1–3 Mbps. Viasat customers can expect all their internet traffic to be deprioritized, meaning that their data gets pushed to the back of the line of all Viasat customers’ data.

Many DSL, cable, and fiber internet companies are discontinuing data limits, but there are many others that continue to keep them in place. Look to see if your internet service has a data cap in our guide to ISP data caps.

Problem: You have weak Wi-Fi signals

Walls, distance, and even microwaves can interfere with your Wi-Fi signal. Weaker Wi-Fi signals mean slower speeds and frequent disconnects

You can tell if signal interference and weak Wi-Fi signals are your issues if your connection works well near your router but is extremely slow in the next room.

To fix weak Wi-Fi, first, check your router’s placement. You want to make sure your router is in a central and elevated location and away from things that can affect your Wi-Fi signals (like walls, Bluetooth speakers, etc.). 

If that doesn’t work, you might need to replace your router with one designed for longer ranges or better coverage—or you can add an extender to your network to stretch Wi-Fi signals into a previously unreachable area

Check out our guide to long-range routers if you need better Wi-Fi coverage. It goes over both mesh Wi-Fi systems and standalone routers to help you figure out how best to access the internet in every inch of your home.

Problem: You have high latency

Latency is the time data takes to make a round trip from your device to the destination and back. A high latency creates noticeable lag: an extended duration between your physical actions and the results displayed on your screen. This can be particularly frustrating with online gaming or video calls. 

High latency is difficult to work around. It depends partially on your physical distance from internet servers, network congestion between you and the servers, and your internet provider’s infrastructure—things that are mostly beyond your control. Internet type can also play into latency as well. 

For example, satellite internet has high latency because all your data must travel to space and back, both coming and going to your device. Newer types of internet, including fiber and 5G mmWave, have lower latency because they can handle faster signals. 

If you’re looking to lower your latency for a better connection, check out our report on the fastest ISPs. It dives into which internet services have the best tested speeds and lowest average latency.

Problem: You have slow or outdated devices

The problem might not be with your internet connection—it might be with the device you use. Your computer, tablet, phone, or gaming console could be outdated and not capable of processing today’s Wi-Fi speeds.

For example, the old (but much loved) PlayStation Vita handheld console supports up to 150 Mbps per second because it uses a Wi-Fi 4 radio. That speed can decrease based on the router it connects to and the security protocol it uses. The Vita will never see speeds beyond that 150 Mbps limit.

If you have speed issues on a desktop or laptop, try power cycling the device. This clears the memory of any junk, refreshes your connection, and cleans out unnecessary processes and temporary files. Speed issues tend to happen due to an overworked processor, and a quick power cycle—shutting it down completely for 30 seconds—will “clear its head.”

Other things that can slow down your devices include the following:

  • Too many open applications
  • Too many open browser tabs
  • Outdated software
  • Outdated drivers
  • The operating system needs to reboot to install updates
  • Patch downloads
  • App downloads
  • Malware

Avoid overwhelming your computer’s CPU by closing unused applications and browser windows. Keep your device’s operating system up to date by allowing auto-updates, and keep your antivirus definitions current.

Problem: Your provider is throttling your connection

Internet providers can throttle your speeds, causing a slow connection. We’ll go over throttling briefly here, but you can get a more in-depth look at the subject in our guide to network throttling.

We’ve already discussed a few circumstances where a provider might throttle your speeds—like if you go over your data cap or if there’s too much congestion in the network. But your provider might also slow you down if it flags your internet activity as potentially illegal or if it generally doesn’t want you to do a specific type of activity (like torrenting). 

To see if your provider is throttling your internet, run a speed test normally and then run it again using a VPN. If your speeds improve with the VPN, congratulations! You’re throttled.

Other factors that affect your speed

Your internet plan’s maximum speed

Internet speeds are measured in megabits per second (Mbps). This refers to your connection’s total bandwidth, not the actual time data uses to make a round trip to a website and back—that’s called latency.

Providers usually advertise their internet speeds as “up to” a certain number of megabits per second, and there’s usually some fine print that says those speeds are not guaranteed. Internet providers are mostly in the clear legally if your internet doesn’t actually perform up to the highest advertised bandwidth.

Realistically, you may pay for 400 Mbps per month, but you may not see that maximum due to hardware issues between your internet provider’s operator—a device that communicates with multiple modems—and your physical internet connection. Utility pole connections, your buried cable, and so on all play a major factor in how your connection performs.

If you need a refresher on internet speeds and what they mean, check out our guide to internet speeds.

Your upload and download speeds

You upload and download data every day, whether you’re on a smartphone or a laptop. For instance, when you access a website, you upload a request to that website and then download temporary files from the site to view it in your browser.

If you don’t have issues with streaming on Netflix or downloading files but are still experiencing some symptoms of slow internet speeds, your issue might actually be with your upload speed.

Cable, DSL, and satellite providers give customers way less upload bandwidth than download bandwidth because most people request much more information from the internet than they send. Upload speed is typically an issue for heavy uploaders—like Twitch streamers, people who work with video or audio, or those who often have to share large files. 

The best way to improve upload speeds is to switch to a fiber plan. Fiber-optic internet connections often give customers upload speeds equal to their download speeds. If you don’t know what kind of speeds you really need, check out our recommendations for upload and download speeds.

Your internet connection type

There are a few different technologies internet providers use to deliver your connection, like cable, fiber, satellite, or DSL. Your internet connection type plays a huge factor in your overall speeds.

Satellite internet transfers internet signals from a base station to a satellite to a receiver at your home. Because all your information must travel such a long distance both ways, satellite internet can have very high latency compared to other types of internet, which slows things down. 

DSL internet uses phone lines to carry data. It can’t handle the same amount of bandwidth as cable or fiber. DSL internet tops out at just over 100 Mbps, and its electrical signals tend to degrade in quality over long distances. 

Cable internet is faster than DSL because it uses coaxial cables that have a higher bandwidth than phone cables. Speeds can reach up to 1,200 Mbps.

Fiber-optic internet is one of the newest types of internet, and it’s the best wired connection you can get. Fiber uses light pulses to send your internet data, so it has lower latency than other internet types as a whole. It can also carry much more bandwidth than cable or DSL, offering speeds up to 5,000 Mbps. It’s less prone to network congestion and offers equally high download and upload speeds.

Overall, DSL and cable are the most common internet types while fiber is newer but scarce. Satellite is best for rural areas where the other three types can’t reach.

How to troubleshoot a slow connection

First, know your plan speed

You need to know how much speed you pay for each month and compare that number against the speed you’re actually getting now. Look on your paper bill or log in to your online account to see your plan’s advertised maximum speed.

Next, run a speed test and compare

Running a series of speed tests while connected to different points in your network can help you figure out where your speeds are slowing down. We’ll break the testing process down into two sections.

Part 1: Test the modem

Your first speed test is to see if you’re getting the correct speeds to your home compared with what you’re supposed to get from your internet provider. To get the most accurate results for your initial speed test, unplug your router from the modem and connect a computer to the same port on the modem using an Ethernet cable. If you have a wireless gateway, just plug it into one of the Ethernet ports.

Warning: We don’t recommend browsing the internet for extended periods of time without using a router. Your router has some excellent built-in security features that protect your network from viruses and malware.

This first test should give you results that are close to the speeds promoted with your plan. If not, try to track this issue over multiple days and times of day to establish a pattern. Contact your internet provider to talk about why you’re not getting the correct speeds if you continue to see lower than expected results

Part 2: Test the router

If your modem isn’t the issue, the next step is to test the router. Plug the router back into the modem and run multiple speed tests using your wireless devices, and wired devices plugged into the router’s Ethernet ports.

If you see a vast difference between the modem and router tests, then your router is causing your connection slowdowns—or the Ethernet cable tethering your router to the modem.

Keep in mind that not all wireless devices experience identical speeds. Their connections depend on the hardware inside no matter what router you use, so a budget Samsung phone will have slower Wi-Fi speeds than an expensive wireless card plugged into your desktop.

To troubleshoot router problems, follow these steps:

Step 1: Unplug the router’s power, wait 30 seconds, and then plug it back in.

Step 2: Make sure all cables are connected securely and that all ports work.

Step 3: Update your router’s firmware. You can do this by logging in to your router’s web interface or mobile app. (Your ISP likely does this automatically, but it’s worth checking.)

Step 4: Reposition your router.

Step 5: Move wireless connections to the best Wi-Fi band.

Step 6: Change Wi-Fi channels in your router’s interface to find one that’s less crowded.

Step 7: Try a factory reset by pressing the reset button located on the back of your router.

If none of these steps work, you may need to upgrade to a newer or more powerful router. Internet tech advances rather quickly, and if your router is more than a few years old, it might be time to get yourself something more modernIf you’re looking for router-buying guidance, we have recommendations for the best long-range routers, the best modem and router combos, and the best routers for Xfinity.

Check for Wi-Fi dead zones

Wi-Fi problems can stem from multiple factors. It could be your router’s range, a crowded frequency channel or band, or signal interference caused by physical obstructions and other electronics. 

You already know that you should place your router at a central and elevated location for the best coverage, so we’ll assume that you’ve already done that and pointed your antennas in the right direction.

Go to different areas of your house with a computer or smartphone and watch the Wi-Fi signal strength indicator. If you notice a lot of dead zones, you may need to move your router again (if they happen in areas where you normally need Wi-Fi) or invest in something to boost your Wi-Fi signal to that particular area. You can also make a Wi-Fi heatmap if you want to get more precise with it. 

If you have more than a couple of issues with Wi-Fi dead zones, we recommend upgrading to a mesh networking kit. They usually ship with at least two nodes—one that connects to your modem and another that communicates directly with the first unit—to create a ”blanket” of coverage. There’s no centralized point, and you can easily add more nodes to extend coverage. Moreover, devices seamlessly switch between nodes as you move about the home or office.

If you prefer to stick with the traditional router, you could add a Wi-Fi extender or powerline adapter, However, we still prefer mesh router kits versus the router/extender setup.

Reorganize your Wi-Fi connections

If you’ve already pruned your Wi-Fi connections of unnecessary devices, it’s time to make sure all active connections are on the correct Wi-Fi band. 

Most modern routers offer two Wi-Fi bands, which each create their own visible Wi-Fi network. By default, these are usually labeled with their frequency bands, but it might be different if you’ve changed your Wi-Fi network’s name. 

These bands operate on two different frequencies: 2.4 GHz and 5 GHz. The 2.4 GHz frequency band has a better range, but it’s slower and more susceptible to signal interference from other electronics. The 5 GHz band is faster but can’t travel as far. 

Basically, you want to use the 5 GHz band for most bandwidth-heavy applications like streaming or gaming. Devices that don’t need that much speed—like smart home devices—should use the 2.4 GHz band instead.

Typically, you can change the Wi-Fi band each device uses by logging in to the correct Wi-Fi network on each device. However, some routers broadcast only one network name and automatically selects the best frequency band for your device. This can be problematic if you really need the faster 5 GHz connection, but the router forces your device to use the 2.4 GHz band.

Change your Wi-Fi band’s channel

Both the 2.4 GHz and 5 GHz frequency bands used by your router split into multiple channels, similar to how analog and digital TV works over the air. Like any network dealing with lots of information, these Wi-Fi channels can get too crowded, which can cause slowdowns. This is especially true for compacted living situations like apartment buildings. 
To find the best channel, you can use an app like NetSpot for Windows or use the Network Diagnostics function on a Mac. Changing your Wi-Fi channel involves logging in to your router’s web interface and manually selecting the ideal channel.

Check connected devices

As we mentioned before, sometimes the issue isn’t with your internet connection—it’s with the smartphone, computer, or tablet you’re using to access the internet. It may need a reboot, it may be outdated, or you have too many apps and programs open, bogging down the device’s processor.

Manage your network

If you’ve made it this far and you’re still experiencing problems with slow internet speeds, run through the tips in the home network traffic section of this post if you haven’t already. 

Your speed issues most likely stem from your internet provider’s reliability or the traffic on your own home network. Even if you’ve organized and trimmed down your number of connected devices, you could still not have enough bandwidth at certain times of day to cover everything your network has to handle. The only solution to this is to either use the internet less or get a faster internet plan.

Check out every provider and plan in your area to see if you can get better speeds for a better deal.

Quick fixes for slow internet speeds (and why they work)

Before we dive in, take an internet speed test. Measuring your internet speed and knowing how it compares to the speeds you pay for is an important part of diagnosing a slow connection.

Fix #1: Power cycle your modem and router (or wireless gateway)

Your modem and router work hard, and sometimes they need to refresh with a quick power cycle. Simply pull the plug on both units, wait 30 seconds, and then plug the modem back into the wall outlet. Once it properly boots, do the same with the router.

In the case of a wireless gateway, pull the plug, wait, and plug it back in.

Draining both units of power allows them to clear the system memory, clear up any local communication issues, and reestablish fresh connections. Moreover, a power cycle allows the modem to resync with your internet provider’s operator—a device that communicates with multiple modems. It also refreshes your router’s public IP address.

Overall, a power cycle can really give your internet speeds a boost on your side of the modem.

Fix #2: Move your router to another location

Many people hide their routers or wireless gateways in closets, behind furniture, or down in basements. Don’t be one of those people unless you want excessively bad Wi-Fi.

Instead, put as few physical barriers between your router and your devices as possible. Walls, floors, ceilings, doors, large furniture, and similar obstructions can barricade your Wi-Fi signals and reduce connection speeds, especially over longer distances. 

Certain signals from other devices can also interfere with your wireless speeds. These include microwaves, Bluetooth speakers, baby monitors, and cordless phones.

For the best Wi-Fi coverage, place your router in a central, elevated location, or at a location where you use Wi-Fi the most, like in a home office.

Be sure to use your router’s external antennas (if present) to get better Wi-Fi coverage. Most router antennas broadcast Wi-Fi signals in an outward circle perpendicular to the antenna’s position. For instance, if the antennas are positioned vertically, the Wi-Fi signals broadcast horizontally in all directions.

That said, if you live in a one-story house, keep the antennas vertical. If you live in a multistory house, position at least one antenna horizontally so the Wi-Fi signals reach the additional floors.

Fix #3: Use the internet during off-peak hours

If you know there’s a big download in your future—the latest version of macOS or a 100 GB update for an Xbox Series X game—you might want to schedule a time when you don’t need to do anything else online. The early morning hours are ideal when everyone is asleep and no other downloads currently hog your bandwidth.

Operating systems tend to wait until the early morning hours when you’re fast asleep. Game updates, meanwhile, typically require you to manually start the download. Other updates aren’t quite so accommodating with your schedule.

If your internet gets too slow to stream during certain peak hours, download the content earlier in the day (or again, in the middle of the night) so you’ll be ready to binge watch all of Avatar: The Last Airbender without buffering-related interruptions.

Fix #4: Upgrade your internet plan

You may need a faster plan if more people live with you now, if you transitioned to working from home, or if you generally use the internet more than you did before. Enter your zip code below to find a speedier plan that’s available in your area.
