When i start my computer or a computer on my network connected to the wireless router (using wpa encryption with t-skip algorythms) the internet works fine... for about 2 minutes or so. then the network icon shows i am still connected, but i cannot access the internet. i found that if i disable the wireless card network connection and then re-enable it it reconnects and works fine. The weird thing is that when i reconnect it says "connnection failed", and then a different message says i am "connected".
I am using:
Dlink DI-624 router connected to comcast cable internet
all pc's have dwl-520 cards. everything is the "extreme" g version
any help would be appriciated, thanks.
