Why is my Optimum internet speed slower than advertised?

Your speeds can be slower than your plan’s advertised speeds for several reasons. Outdated and faulty equipment cause slowdowns, as does heavy use of your local network while you run the test. Your provider may face internal issues during the test, or there could be a traffic jam between you and the test server.

About our Optimum internet speed test

The Optimum internet speed measures three things:

Download speed: The speed at which your device pulls data from the internet. Usually measured in Mbps or Gbps.

Upload speed: The speed at which your device sends data to the internet. Usually measured in Mbps or Gbps.

Latency (Ping): The time (measured in milliseconds) it takes for a signal to travel from your device to an internet server and back. Lower latency means your connection has a better response time for activities like gaming and livestreams.

How does the Optimum internet speed test work?

First, the test client on your device determines your location and finds the closest server. It then sends a tiny bit of data to the remote server, which sends a bit of data back to the client. The client records the amount of time the exchange used and then repeats the test a few more times. The test ends, and the client presents the lowest roundtrip measurement in milliseconds. This is your latency.

Next, the client establishes multiple connections (called threads) to the remote server and requests test data. As the client downloads this data, it measures the speed and makes adjustments as necessary—like opening more threads and requesting more data—to maximize the full bandwidth of your internet connection. The test ends at the predetermined time, and the client presents your current download bandwidth in megabits per second.

The upload test works in reverse: the client sends test data to the server and takes measurements. The test ends at the predetermined time, and the client presents your current upload bandwidth in megabits per second.

Optimum internet speed FAQ

How fast are Optimum internet speeds?

Optimum provides cable internet with speeds up to 940 Mbps in most of its coverage area. The former Suddenlink network is mainly known for rural cable internet, so you may find slower plans in those areas than what we list above.

Optimum provides fiber internet too, mainly in the New York tri-state area. The fastest fiber is 940 Mbps in most areas, while its new 2 Gbps and 5 Gbps plans are hard to come by.

How do I get faster internet?

You can get faster internet by upgrading your internet plan. If you can’t upgrade your current speeds and feel stuck with bad service, you can also switch to a new provider.

Run a search with your zip code below to see what kinds of speeds you can get in your area.

Is cable better than fiber?

Fiber internet provides equal upload and download speeds, whereas cable internet does not. Plus, you can get fiber plans faster than 1 Gbps—Optimum’s cable internet maxes out at 940 Mbps.
