Hello, a few months ago my laptop started randomly turning off its capability, however last week it turned off completely. It occasionally turns but not for too long. The wifi button does nothing, no matter how much or how I press it, it stays orange. At the mobility center the function to turn on wifi is greyed out. I tried checking BIOS, everything is fine there, I tried checking WLAN AutoConfig at services.msc, everything is fine, and ofcourse I tried different drivers and stuff to no help. The interesting thing is that I had mini usb wireless adapter and it made wifi work, however I accidentally broke it and am unable to buy a new one at the moment.
P.S. I should also mention that I tried to lower the roaming sensitivity, make it that the laptop does not turn off the adapter on power saving mode, checked whether radio is enabled, troubleshoot the problem as admin, with no help. The driver is Ralink RT3290 802.11bgn Wi-Fi Adapter. I pretty much tried everything out that I can find but nothing helped, hopefully someone will be able to help me. The laptop is HP ProBook 4540s. If you need more info I can gladly provide it.
