Windows 10: Unable to connect to the network

I have a N600, Model C3700 and it's been several months now that for some odd strange reason wiffi connection tab when  selected it's blank and only gives me the message "cannot scan the wireless networks. Make sure your wireless adapter is on and is not disabled". So far I know that the cable modem router is on and the power adapter is on. I haven't had any complaints of the wiffi being dropped except for blackouts in my neighborhood or from service provider. I have a pc windows 10. After windows 10 was upgraded a lot of things where not working properly. Although, it seems that Microsoft been working on the glitches windows 10 has been experiencing. Your help is greatly appreciated.
