Try re-installing the latest software for your router from the router manufacturer's website. This will be the most recent version and chances are the version on your disc is outdated.
I have a gateway puter running Vista and it stops recognizing the wireless router.It lists it as removable hardware which I guess it is but I have to go in and reinstall the software because the sys diabled the wireless router.The auto install goes to the original download which is supposedly corrupted but I just reinstalled it when I did a FULL SYS REINSTALL.So I put in the disk and reinstall from there to solve that but--- WHY isnt it just working like it used to??
This is SOO FRUSTRATING to reinstall after turning it off.
