Win 7 multiple code 37 errors in device manager

Had an issue the last week which appeared to be resolved but
Now I have lost internet access- wireless Ethernet device has got an error code 37 in Devi e management so have numerous others
Including monitor, processors and some USB devices.( not at home currently so can't list properly). I've tried sfc scan now but
No issues. Ran various antivirus checks, malware bytes Spybot and a rootkit checker all have found Nothing. The
Most frustrating thing is not being able to get internet access. Couple of other things of note, pc is asking for the windows activation code again which it won't accept as no internet Access.
 
Boot into Safe Mode, login as Administrator.

Now try to set the Activation code
