Are you sure that your driver is up to date for the wireless card?

Either try to update the wireless card through device manager or go to the manufacturers website to download the up-to-date driver, if the latest one isn't currently installed.

I tried updating true device manager but says its up to date,so i installed driver genius and up dated everything but still the same keeps happening.
im installeing microsoft updates at present so see how that gets on.
