Connection how come i get disconnected every 2 hours (simultaneously) can u help me with this??

Change channels to 1-6-or 11.

check is to make sure you are NOT using "IEEE 802.1x authentication for this network."

You can find at setting under "Wireless Network Connection Properties" and then under "Authentication" tab of your network properties.

This particular authentication method is periodically logging you off the network and re-authenticating.

Check the adapter and usb ports in device manager to make sure that windows is not shutting them down to save power.

Cordless phones and wireless ethernet cards use overlapping frequencies.As a test, you can unplug the AC cords from all the cordless phones in the area and see if it helps.
