Try to change to Fangzhuang (Fortune) in Beijing if you have the option.
My last apartment didn't have any options, and the provider sucked: 4 Mbit cost 55 RMB/month (if you paid in 6 month blocks) and couldn't manage 1 Mbit down to Chinese sites, The up actually wasn't bad, sustaining 1 Mbit was no problem. Oh, and when I asked the install tech to give the PPPoE password so I could put it into my router, he refused up to the point where I refused to allow him to leave my apartment unless he gave it to me. It was a farce.
My new place gives me a choice of that same old provider, that no one uses, or GTao (I have used them in the past, good service) or Fortune. Fortune offered me 2 years of 20 Mbit down/3 Mbit up for 1880 RMB. So for about $3 USD more a month compared to the old service, I can get 18 Mbit to HK providers (if they can source it) and the up can go to 3.5 Mbit, so I think the rate cap is actually around 4. To Texas sites, I still sustain about 12 Mbit down and 2 Mbit up because they don't seem to be able to feed me more, though my LA based VPN can cut those numbers in half (any recommendations for a new VPN provider?). Latency still sucks, of course.
All of this only applies if you live in a 'mansion' (apartment/condo building, depending on how you like to think of it). If you are in a hutong, fiber internet service isn't such a huge requirement when you still don't have indoor toilet facilities.
