Had Quantum before they swapped to Brightspeed. I've had zero issues except for the one day a week or so back when everyone was having problems, but it was solved by the next day.

I had Mediacom before that and it was hell. Speeds were garbage and they kept jacking our prices up. I think I pay 1/3 of what I was paying Mediacom and my speeds on Brightspeed are usually 900+ down and up. Would recommend them.

Noticed someone else mentioned customer service is trash for Brightspeed, but tbh, customer service has been trash for every internet service I have ever had. They all hire out to other countries.
