Hi there,

I've been trawling forums all day but I still can't get WPA1/2 authentication working on my laptop, insanely frustrating. I can connect on WEP or no encryption and my wired controllers working without a hitch but everything I've tried with the wifi has failed.

I'm using 9.04

Here's my system info:

There you go! Really hope someone can help me out with this, it's been driving me absolutely bonkers.

Cheers!

same thing here, it used to work until today.
seems to be driver-related.

I just installed Jaunty on a Toshiba 350 with a AR928X and I couldn't connect to any wireless networks even though it could see them. It would ask for the wireless network password, attempt to connect, and then ask for password again. After searching around the forums I found this post:
http://ubuntuforums.org/showpost.php?p=7200293&postcount=6

and after installing linux-backports-modules-jaunty it started working flawlessly. It might help you too.

Looks like my biggest issue was that I'd been playing around with the configuration too much. Did a fresh install and reinstalled wicd and the backports and all is well.

Cheers!

Seems that I was wrong, there wasn't anything wrong with my wireless setup, it seems that the Linksys WAG160N fails hardcore with *nix wifi drivers. I had a chat the the Linksys tech support and they didn't have an answer for me.

Here's my advice:


IF YOU WANT TO RUN ANYTHING OTHER THAN AN M$ OS DON'T BUY A LINKSYS WAG160N

The problem appears to be related to Wireless N and the ability of wireless abg to connect to it. (I am speculating but I see nothing else)

I read that wireless N is backwards compatible, but I cannot get it to work.

The clue for me is iwlist scanning

I get:
Scan completed :
Cell 01 - Address 00:1F blah blah
ESSID "NETGEAR"
mode:Master
Channel :1
Frequency:2.412 Ghz (Channel 1)
Quality 93/100 Signal level: -39dBm Noise level=-99dBm
Encryption key:off
IE: Unknown: 00074E4554474515

Repeat with IE Unknown and what looks like Hex for about 16 lines

Bit rates: 1 Mb/s -------- to 54 Mb/s
Extra: tsf=0000000cc4b82c52
Extra: Last Beacon: 5276ms ago

So far I have seen no information about what IE: unknown is about.

I'd be very grateful if someone could tell me at least that.. Then maybe I can figure out some more

My PC is Acer 2480 with Atheros AR242x 802.11abg wireless card

I have no trouble to get onto wifi hotspots.. just my wireless router.. which is a netgear WRN 2000 802.11N protocol. I suspect hotspots don't use wireless N (YET), but that doesn't help... with routers now mostly adopting wireless N, the problem will get worse if my hunch is right
