I've recently built a PC and didn't realize that the WMP54G Wireless PCI Adapter by Linksys is not compatible with Windows Home Premium 64-bit OS. Linksys hasn't produced a driver that addresses this issue, which was confirmed by their tech support after a lengthy conversation I had with them about the issue. When I google the issue there is a generic work around that involves downloading a particular driver from the chipset manufacturer (Ralink). After attempting this work around myself I find that I'm stumped. The work around involves the use of a "Network Controller" in Device Manager, but when I open Device Manager there is no "Network Controller". It has "Network Adapters" which I tried using for the driver update by selecting the Linksys adapter and trying to install the Ralink driver on that, but it doesn't work... Any suggestions?
