Linksys Wireless G PCI adapter not working on Winodws 7 RC


  • I just installed the RC and I have a Linksys WMP54G wireless G PCI adapter and it is not appearing in the adapters list. My network center obviously cannot find any connections as a result. Also, the back of the PCI card on the back of my computer usually has a green light flashing, but it hasnt been on ever since i installed the RC. I had Beta before this, since it was released and didn't have any problems.

  • Linksys... hmm, Well the driver should work from Vista, but it is not showing up in the adapters.... Try a restart and then after the restart see if there are any unknown adapters in the PCI slots list them:

  • I found out, I had to go to device manager, then go to the network adapters and it was there as "unkown adapter" or something like that.  Then i updated the driver by loading the drivers from the CD.  hope this helps if anybody else has this problem

  • Thanks! I had the same problem and resolved it by your suggestion. Windows 7 doesn't recognize the Wireless-G PCI Adapter so you have reinstall the driver from their website:

  • Okay, now I have a good Solution for your Problem:

    1- Go to --> Click Support --> click Windows      OR    Click here !

    2- Download " PCI/mPCI/CB (RT256x/RT266x)"

    3- Run and Install it (as adminisrator)

    4- go to "Device Manager" and right click on "Network..." (at "other devices")

    5- update Driver software... --> Brows my computer for driver software --> let me pick from a list ... --> Click "Network adapters"

    6- Select "Ralink technology Corp." at the Left Column then Select "802.11G Wireless PCI Adapter"[With Capital G]

    7. Enjoy :-)


    As you Know your Wireless Card is "Linksys" but LinkSys is "CISCO"! and also Its Chip is "Ralink"!

    Linksys Name: "Wireless G"

    CISCO name: "WMP54G"

    Ralink Name: "RT256X/RT266X or ...!!"

    :-( what a mess
