Hey guys, i've had this problem a while now and it's bugged me enough for me to seak help

Sometimes when I connect to any of my steam games (left 4 dead, team fortress 2, counter-strike 1.6 or source) it disconnects soon after entering the server or before it's even loaded.

Sometimes this disconnects the internet completely and I have to right-click repair it to renew the IP address and stuff, then it usually works. Once i'm in a game and it doesn't disconnect soon after loading however, i can stay in there for as long as I want and switch servers. It only seems to happen when i'm loading up a server for the first time in the day or whatever.

My internet is wireless, BT Home Hub 8mb
I've got a Netgear WN121T adapter, which is suited to gaming. My signal is always Excellent or Very Good.

I've tried Port Forwarding, not sure I did it 100% right but that didn't help anyway. I've also tried putting commands into the launch options under properties on the games and that hasn't worked either.

Anyone know how to fix this? :X Thanks
