Cards with a ralink 2500 chipset

Cards with ralink 2500 chipsets are normally recognized on the interface ra0 or rausb0 using the native driver that comes with MEPIS Linux 7.0. Here is how to get online with this chipset:

  1. Go through the basic steps (see Section 5.7.1), choosing to disable Ndiswrapper.
  2. Be sure to set up without encryption first if possible.
  3. Sometimes Ndiswrapper interferes--your card may or may not show up on the interface wlan0. If you experience problems, you should blacklist Ndiswrapper. Right-click on the desktop and choose Run Command. Type:
    kdesu kwrite /etc/modprobe.d/blacklist
    
    and enter the root password when prompted. Add these two lines anywhere:
    #interferes with native driver
    blacklist ndiswrapper
    
  4. If your card is recognized but you can't set the SSID/ESSID, put the network down first by entering as root:
    ifdown ra0 (or: rausb0) 
    iwconfig rao (or: rausb0) ssid yourname
    ifup ra0 (or: rausb0)
    
  5. If problems persist, it may be because of problems with Knetworkmanager. Try entering as root:
    modprobe rt2500
    iwconfig
    
  6. If you now see an entry for ra0 (or rausb0), then enter:
    rmmod ndiswrapper
    rmmod rt2500
    modprobe rt2500
