Windows wont let me enable wifi adaptor

You have multiple devices operating on the same frequency it would appear.
Sorry but I don't have a solution for that

yeah, people argue about which av is best to use. I just keep saying MSE it's not the best protection but it is far less likely to cause system problems like that.

I have the tenda W322P as well with exactly same problem i.e. says it's enabling when it isn't, remains defiantly disabled. In device manager it says it's working fine with no resource conflicts. It doesn't make any difference which driver I install (inc. windows default). I reinstalled windows 7 a couple of days ago so it is still very 'clean'. I avoided AVG, Avast etc etc and went with your advice of MSE. All was fine for about 48 hours whilst browsing a web page and then without warning: "you have no network connections" (or words to that effect). It's been like that ever since? This happens every time I re-install windows 7! I've run SFC utility but no problems found with the system integrity. I've repeatedly installed and uninstalled the device driver (with reboot) which makes no difference at all. Any suggestions please?

Back on LAN temporarily!

I can't see it being the hardware as it always works fine initially after a windows reinstallation, but isn't long before it breaks down yet again!!

Tried windows diagnostic/repair utility which reports that my network adapter has a problem; but as the device manager simultaneously reports that it is 'working fine' [contradictory or what?], I now suspect a windows 7 problem rather than anything to do with the Tenda hardware/software?

Booting into safety without the firewall enabled makes no difference as does with removing the wireless drivers prior to entering safety. System restore makes no difference either!
