I have a k450 Lenovo Desktop. I have been using my wireless internet through my router for approximately 6 months with no problems and then it suddenly stopped working 2 days ago. My router is fine because my laptop and cellphone can both connect and work fine. My Lenovo desktop can't detect any wireless internet connections anymore. I checked the Network Adapters under Device Manager and there is only one : Realtek PCIe GBE Family Controller. If Im not mistaken, there should be a LAN adapter. I have scanned for problems and it tells me to plug in Ethernet cable(I have never used the cable, been using wireless for 6 months). Under my Service, I have checked my WLAN Autoconfig and it is running. A day before my computer went awol, my pc did automatically perform a Windows Update. But it was working for an entire day before it stopped. Any suggestions would help. Thanks.
