Connection Problem Troubleshooting

[Netzeek]

I've been having this problem ever since I first installed BF2 and it's very frustrating as I really want to play the Project Reality modification. Basically, whenever I try connecting to a server, I get the message which states that I couldn't connect to the server and that I should check my network connection(s) and try again. I'd greatly appreciate it if anyone could help.

Thanks in advance,
Netzeek.

I bought a license for BF2, put on his patch PR, while trying to connecting to any server kicks me to the desktop without any errors, PR simply terminates. But a single game (the game with bots) are no problem

OS: WinXP

I'm having a problem with my wireless.

I seem to only get these problems playing PR.

Now we all know how dodgy it is to game with wireless but I am having to make due for the time being. Now, I don't really lag in online games, but as soon as I step into PR my ping will spike to 100-999 for 5-30 seconds. I alt tab out and can't browse the net at all, even though I'd previously been on it all day/night browsing fine.

There is something going on with this game but I can't put my finger on it.
