Vista - World of Warcraft WOW

I have a new computer with Vista 64 Ultimate. I have Only Wireless network connection.

And my problem is disconnect after 30 sec or so...
The network works just fine with all other pograms, but when I connect to WOW it stays connected for 30 sec or so. And when I close WOW I can't connect to internet with the web browser. I have to reset the Wireless network to enter the web, then it works just fine until I try to connect to WOW, then the same problem appears again.

What to do?
Please help!

Hello,

You didn't mention what kind of wireless card you're using. I'd suggest going to the website of the maker of the wireless card and making sure you have the latest drivers. That may help your situtation.

Hi. I have 2 USB wireless adapters. 1 D-link DWA-142 and 1 Netgear WN111.
Use only one at the time to chek with one are the best. And I have the newest drivers on both, but that don't seem to help..

But thanks for the notis

My problem is over. I got my a wired connection.
