Wireless adapter failure to detect networks.
I recently installed a Belkin N300 on my backroom PC which has Vista Ult OS. The purpose was to connect to the WiFi router/modem of my main PC which has Windows7.
I installed it exactly as instructed by the manufacturer using the disc that came with the adapter. That is, run the disc first and install the adpater when prompted. It said it installed successfully, and Device manager said it was running properly, but in practice it could not detect any networks. Network discovery was turned on, and no yellow warning triangles.
After about an hour of fruitless attemtps to fix the problem, I did a bare bones installation of Vista and installed the adapter on it and it worked perfectly. And it continued to work even after all the various 3rd party software and Windows updates were installed. However, if I now uninstalled/reinstalled it, it would no longer detect networks, even though Device Manager said it was running properly.
I was curious to see if the problem was an incompatibility issue with Vista, so I installed the Belkin adapter on my main PC which already had Windows7 fully loaded. And then tried to connect with a wireless router/modem on the Vista PC. And I got exactly the same result ... everything green lights, but in practice it could not detect my WiFi modem on Vista, or any other networks in the vicinity.
So I repeated the process of installing the adapter on a bare bones installation of Windows 7, and as on Vista, it now worked perfectly. And continued to work when the other applications were installed. Likewise, if it was now uninstalled/reinstalled, it failed to work.
It then occurred to me there was a WiFi wireless adapter module that came with the motherboard of my Windows 7 installation. On the Intel installation disc that came with the mobo, it was labelled: WiFi 802.11bgn Wireless Adapter. I installed this adapter on the fully loaded Windows 7 installation using the Intel mobo installation disc,and it was exactly the same scenario as the Belkin ... that is, all green lights, but not able to detect any networks.
In like manner, it installed and ran perfectly on a bare bones installation of Windows 7. And continued to run even after all other applications were loaded. But once again, if it was now uninstalled/reinstalled it failed to detect networks.
