Step 1. Login as root or use sudo on each step

Step 2. Install ndiswrapper on Ubuntu

aptitude install ndiswrapper-utils-1.9

Step 3. Download Windows XP driver 1.40 from D-Link ftp.
*ndiswrapper fails in loading 1.50 driver – USE 1.40

Step 4. Unzip downloaded driver

  1. Emacs is not installed by default on Ubuntu, so you should update the tutorial to use for example “gksudo gedit /etc/modules” for a GUI editor or “sudo nano /etc/modules” for a console based one.

  2. The wireless device is not showing up under iwconfig, does this only work for 32 bit systems or both 32 and 64 bit ones?

  3. I do not think I would buy any more D-Link products since I had really bad experience with both WBR-1310 router and WUA-2340 USB adapter. They both have extremely unreliable wireless connectivity that drops wireless connection every hour. I even received a replacement WUA-2340 but it did exactly the same thing as previous one.

    I have also tried many other combination of routers and adapters with exact same environment but nothing beats these 2 products’ unreliability. Actually except these 2, everything else worked flawlessly for months. Tossing these out.
