Making DLink DWL-650+ PCMCIA Wireless card work under linux

The DLink DWL-650+ PCMCIA Wireless card doesn't work on recent Linux distros (I tried Ubuntu Hardy to Jaunty). After plugging in, the system hangs with CapsLock flashing.

Turns out the card is handled by acx module and the support is broken for this card. So use ndiswrapper instead.

First blacklist acx module. Open /etc/modprobe.d/blacklist.conf file and add the following line

blacklist acx
Now install ndiswrapper
sudo apt-get install ndiswrapper-common
Now get the Windows driver for the card from here. Extract the file, go to the winxp folder and,
sudo ndiswrapper -i AIRPLUS.INF
The card should work now.


  1. Just did this under Karmic and it worked like a charm on an old Thinkpad T30. Thanks so much!

  2. Worked for a 650 on Linux Mint LXDE. Thanks for sharing this, sir.
