Install Linksys Wireless PCI Adapter(WMP54G) Driver for Windows 7 64Bit

     Seems like linksys doesn’t provide wireless PCI adapter driver for new Windows OS. The only way to install driver for Windows 7 is force to install the driver from the chip company.

1. Download the driver from Here
2. Unzip to somewhere. Let’s say “C:\”
3. Go to “Control Panel” -> “Device Manager”, look for this adapter. Normally it will be shown like “Unknown Network Controller” or something like that
4. Click this device, select “Update Driver Software”
5. Select “Browse My Computer for driver software”
6. Select “Let me pick from a list of device drivers on my computer”
7. Scroll down to “Network Adapters” and double click. Then click “Have Disk”
8. In the box that pops up, navigate to “C:\driver_folder”, and select the driver file
9. Scroll down to “Ralink Technology Corp” in the box on the left side. On the right side, select “802.11b/g Wireless Adapter.” (Here I have tried select “Linksys” on the left, and “Linksys Wireless Adapter” on the right. It also works! Just choose whatever you want)
10. Click YES on the warning window (if you see it)
11. Done! (Sometimes the device still might not be working, try to right click the device and uninstall the driver, but DO NOT check “Delete the driver software for this device”, and restart the computer. Then Windows will help you install the driver again)
