@chev65 thanks for the reply. i tried removing ASUS wireless console and Boingo- pre installed apps for wireless, but it does not resolve it.. i was really hoping it could. unfortunately, it does the same.
There is no such thing as an unsolveable networking problem, although it's acting like it's having a wireless management problem, it could also be a channel crosover problem, or the router's firmware is out of date or a few other things. If you havn't tried updating the routers firmware then you need too, if you havnt run a wireless channel scan then you should do so. Please post your routers make and model here.

The next time you lose your connection please post a screen shot of your ipconfig /all here.
