Hey, was hoping someone could help me out here. My wireless card abruptly started behaving abnormally; it's showing that no connections are available when they obviously are. I went in and manually set up my connection- and lo and behold, it connected, yet still shows no networks available (both mine and all the neighbours' networks too.
Details: I'm running Windows 8.1 (the 10 upgrade failed because of my dual graphics card, which was apparently a widespread issue for us 7520 owners) with a Centrino Wireless-N 2230 network card. Troubleshooting steps I've tried included updating the drivers, uninstalling and reinstalling the drivers, uninstalling and reinstalling Intel PROSet/Wireless Tools (not that the program actually works for me), lots of reboots, disabling and re-enabling the wireless adaptor many times, and making sure Windows Update is current, I did a chkdsk /f as well.
So it's obviously working right now on a manual set-up, but that's going to be a problem for bringing my laptopto work and elsewhere. Was wondering if anyone else had other ideas.
Thank you for your message.
