View Full Version : [ubuntu] DWL-G650+ not working

December 17th, 2008, 10:17 AM
I've been doing a lot of reading and a whole lot of experimenting in trying to get a DWL-G650+ (rev b) PCMCIA card working on an Asus laptop running an install of Intrepid 8.10.

It seems the that ACX111 compatibility changes with every revision of Ubuntu so im not sure whether to keep troubleshooting it using guides written for previous revisions, as i can't find anything regarding my wifi adapter for Intrepid.

When i plug the card into the laptop, it is detected by Ubuntu but i can't do anything with it.

IWCONFIG shows the card as being Wlan0 with the nickname "acx v0.3.36"

When i attempt to connect to my wireless network i get an error;

iwconfig wlan0 essid "Home Sweet Home"
Error for wireless request "Set ESSID" (8B1A)
SET failed on device wlan0 ; Operation not permitted.

I can only assume the Intrepid ACX111 driver is still a little fubar with the DWL-G650+

Has anyone had any success with this card and Intrepid?

Have you got installed 'linux-restricted-modules' ?

I think you will also need 'madwifi' packages...

can you show us what 'dmesg' shows when you put in the card?

I have this card working, but in an old laptop with ubuntu 7.04

linux-restricted-modules is for Atheros based cards isn't it? This card is ACX111.

Still can't get it to work properly :/

I have that same card, running Intrepid Ibex v8.10
No problems here.
Here's my configuration info.
Hope this helps.

This is an Atheros chipset based card!!

Pardon my oversight on my earlier post as your card does use the ACX111 chipset.

Here's a direct Ubuntu link on configuring your specific card.

it works but it needs wicd (and linux-restrited-modules) instead of Network-Manager.

has anybody managed to get the 5212 chipset working in WPA enterprise PEAP TKIP MSCHAPV2 ?
