I work from home and have to log into a secure system before I can get into anything. Cox internet service is constantly going out so I have to continually log back in again and again. It is so aggravating! Had them out twice so far and they blame the router (so I've changed it three times, finally buying on that's almost three hundred dollars) and when their service works it's great), changed the modem provided by them and it still doesn't work. After having this happen over and over I remembered why we left them the last time.
