Customer Reviews of Internet Providers in Castro Valley

Gig speeds!

Switched to AT&T fiber so much better. When att fiber was available, I ordered and never been happier. I got Gig speeds for $80/mo. The gateway provided from AT&T was adequate for home user, but I use my own security gateway and access points. The provided gateway of bgw210 would get wifi speeds of 300-400 range and 900 on ethernet. My 3rd party access point would get wifi speeds in the 300-500 range, probably more if I had something that can handle the faster wifi.
