The Windows Update-provided Windows 7 driver for the Linksys WMP54G WLAN adapter is bad

If you're looking to fix the Linksys wmp54g Windows 7 driver issue, you must download the Windows Vista 32/64-bit driver for the Ralink RT256x & RT266x Series
WLAN chipsets, which I have attached at the end of this post.
The WMP54G 4.1 will not inherently recognize these drivers as compatible, so you must force the card to install the Ralink RT61 WLAN Card V2 drivers. Please see the attached image to see the driver installation procedure.
