Ok, I have CoD4 for my PC and everything on it works perfectly, but when I go to refresh the server list in MP, about 25 seconds after that my internet just stops. My router and MODEM both STILL have the correct lights on. I can connect to a CoD4 MP server and play as much as I want, it just seems like the Refresh button jacks it up. Any ideas why and how to fix it?
Thanks.So the refresh button in the game screws the game up?

If so, what exactly happens when you click Refresh? Internet disconnects, that's it?WELL like I said, everything works fine, then I click on Refresh, SERVERS come up, I can click it 2-3 times but then my internet just seems to freeze. My xfire logs off, internet explorer cant connect, and Call of Duty cant find any servers. My laptop can still use the wifi though.
And I posted twice because nobody answered the first time...My apologies for not replying sooner. Things have been very busy for me.

Anyways, since over a week, how is it? Problem still there?

If so, have you tried reinstalling Call of Duty 4?Problem is still there and yes I have reinstalled.
