If you want under 100m.b.p.s. download speed;s you need to switch to a different i.s.p.
My roommate's still have AT&T for their internet and AT&T's speeds suck. I think they're still only 40m.b.p.s.
I've always used TWC, then it became Bright House and for over a year now, it's been Charter Spectrum.
I willl say Charter Spectrum's customer service sucks, compared to T.W.C. and Bright House.
With Spectrum, id their equipment dies or you have service problems due to loose wiring, etc. you'll be waiting 203 days for a fix and most of the time a charge is applied to the fix.
T.W.C. and Bright House didn't do that shit, they just fixed the issue within a day.
Charter has a poor reputation, just do a search on customer complaints for them and you'll see.
