(I'm sorry - I was distracted by a few other cases for a while.)
On a laptop, if there wireless adapter is going bad, seemingly, there are two things to do:
1. try to get it working... go to its entry in Device Manager, and go to the Driver, and Update Driver... if no update is available, that approach is out (and the device is most likely 'broken' a bit.)
2. then, Disable the WiFi adapter in Device Manager, and buy and install e.g. a USB Wireless Adapter (available quite commonly in most stores that sell 'computer stuff'.) Use that for Wireless access and WiFi internet instead. Not quite as convenient as the built-in adapter, but still good and usable.
If this answers your question, please rate my answer. A five-star rating would be appreciated!
