Hi,

Have a windows 7 machine and was running a Belkin Wireless Adaptor that was running fine.

Suddenly the Belkin stopped working. I figured it had died through old age and purchased a new one.

Unfortunately the new one doesn't work either. I've since done a bit of de-bugging and haven't dome up with anything and so have come here hoping to find someone that can help.

New adaptor is TP-Link ac600. Have checked compatibility with my system and should work fine. The AC600 also gets good reviews on Amazon so would expect to work.

Attempted to install following the instructions. Where that falls down is the auto install doesn't find the adaptor, and says it's not plugged in.

When the adaptor is plugged into the USB slot on the windows 7 machine, it doesn't light up, no notification from Windows, and it doesn't appear under the taskbar widget for connected devices.. When I test it in another machine, windows confirms I've just plugged something in, and the light on the adaptor comes on.

Other USB hardware (e.g. printer) is still working. It's only wireless adaptors that I am having an issue with.

If I look in device manager with the adaptor plugged in, the wireless adaptor comes up under Other Devices as "802.11ac WLAN Adapter" with a yellow exclamation mark against it.

If I then try to update driver in device manager i) pointing device manager at the installation CD results in "no drive found", and ii) if I point device manager to Search automatically / online for a driver (via a tethered iphone) I get "Windows could not find driver software for your device".

I've not made any changes to the computer recently, nothing new installed, and Windows says the last update was in May.

Throughout the course of trying a million different combinations of checks and actions, I have disabled USB Selective Suspend Setting, I've tried USB ports that are working for other devices, and several other things, before completely running out of ideas.

Here is the systeminfo:
