Hello and thank you for choosing just answer.
Just to clarify....everything was working fine.....and then you updated (what did you update?)....and now the wireless adaptor is no longer working.
Is the wireless an INTERNAL device?
Or is it a USB device?
Secondly.....have you checked the device manager, and checked for a driver update for the wifi adaptor?
What about rolling back the update you did that caused this? DId you try that?
