Do you have any way of trying a cabled connection instead? I know from experience that some wireless adapters/routers aren't very good at handling online gaming. I'm not saying this is definitely the problem, but from the info you've given us so far this would be my best bet.
Else we need more info on your system.
kay, here's the system info....
1.5GHz Pentium 4 processor
256 Mp SyncDRAM(added another 256, so 512 total)
40GBUltraDMA hard drive
48X MAX CD-Rom (taken out and added a DVD player)
16X Max CD-RW drive
NVIDIA GeForce FX 5500 Graphics Card
That was all on the side of the tower (excluding Graphics Card and things in parenthesis)
the wireless gear is NETGEAR WG111 V2 54 Mbps Wireless USB 2.0 adapter
I would use a direct cable line, but one i don't know if that's possible with our router, I think it is, i saw ports for it in the back, but we chose wireless because the master computer is on the top floor, and we have 2 computers feeding off it's internet. Mine is in the basement, two stories below the router, but still manages 36 Mbps, 64% of the signal.
A friend suggest it might be that the graphics card drivers are not updated.... but I don't think that's the problem.
P.S. thank you for responding so quickly, i didn't think anyone ever would. Your help is much appreciated.
P.S.S I discovered earlier today that Videos (Such as YouTube, or Google Video) do the same thing, all on the internet....if that helps any more.
