It was working just fine on Win7, so I see no reason as to why it shouldn't work just as well with Win 10. Driver updates are of no use, as there seems to be no hardware (anymore) to enable.
Any ideas or suggestions would be much appreciated?
gzt: Is it listed in device manager as 'unknown device' in a different category?
Try Vultr using this link and get us both some credit:
gzt: Are there any Win10 related files on the x55c support page?
I'd ask if you are running the latest bios but that might be difficult. Tried to look for a reset?
richms: Done the keyboard hotkey to turn WiFi off and on a couple of times?
yitz: Try changing the advanced power settings for wireless adapter to maximum performance and check PCI-E settings.
Then disable fast startup.
Reboot to see if the device appears.
If there are newer drivers for your wireless adapter or power profiles available from your vendor for Windows 10 then download and install those.
cdrnet: The wireless symbol appeared for a few seconds, once only, but then disappeared again. Nothing appeared in device manager.
gzt: There are some x55c motherboards on eBay etc maybe can be seen there. If that fails then go for a $20 nano USB wifi if your network is good. : ).
