China Unicom, 4mb up 4mb down rock solid all the time LAN cat5 cable straight into home, into my wireless router np.
720rmb up front for one year.
DNS servers better then most.

Yea go into China Unicom main shop for your area, they will tell you if they can connect you.
Cash deal upfront, no idea what the price is in Beijing, I'm down south.
Latest fiber optic system, router are out side apartment blocks, then send a Cat5 lan into your place, stick that in your router port and away you go.
I pretty sure I ordered 2mb but it runs at 4mb up and down(i seen 5mb) on my torrent software, 700mb film down in less then hour and half.
Streams TV np.
Dont listen to any one telling you Unicom sucks, ever one told me this and now the all sucking there thumbs on crappy China Telecom at twice the price.

yea its going be different for each user on same network, could be there not many sharing the same network box as me.
All new gear here as well CU spent millions building new network down south.
That said the big cites are usually the first to get the best and most money spent, but then there is more users.
What i liked the most was paying a year and forget about it, no hassle with accounts or anything else.
Simpler which makes for a easier life for us foreign dudes..
Shame they ain't wised up to getting there web sites in dual language yet.
Pain in the ass trying to research anything here.
