Well, I reformatted my computer about a month ago, and ever since then, I've been getting extreme lag ( I went to a fight in Alpha, I could only see the CR and the Corsairs there, no outcasts >.>
Some info you may need:
I'm on Belkin Wireless, (Wireless G+ MIMO USB Adapter)
I get 50 kbps download, as opposed to my 150-200 kbps before formatting
I think it may be the drivers, but I can't manually update it, and every program that does it for me wants me to buy their product first, which I won't do.
