Internet Problems

[Romans]

I have 2 desktop computers. Both are Windows Vista. For the computer we will be referring to as "A", it has a Netgear Wireless Adapter plugged into the USB port. For computer "B", it is connected directly to the 2wire modem/router, which is obviously connected to the wall. The problem lies in the fact that whenever the Netgear Wireless Adapter is turned on and connected, the internet on computer B gets disconnected briefly(~2 minutes) and periodically. However, the internet stays connected on computer A. I would like to know why this happens.

while working on net basically we face so many internet problems. So, here i am discussing about the solutions for that...
Three Rules-of-Thumb for Dealing with Internet Problems
1: If you get a message saying the domain name server (DNS) can't find your page and you're sure you've typed it in correctly or clicked on a valid link, try it again - TWO more times! (Sometimes packets don't get there!)
2: If you get a "Not found" message, the page may be temporarily missing because of miscoding at the target site. Try it again tomorrow...or try the home page for the site and send e-mail asking them to restore the page.
3: Be aware that sometimes a page you've visited recently may be coming from your cache (or the cache on a proxy server within your company). To get the "fresh" version of the page, click on "Reload" in your tool bar.
