Fedora 11 and Linksys USB G wifi adapter


I reconfigured my WRT54GL router (not running Linux) to use WPA/WPA2. Previously it was only using MAC filtering. I'm using a Linksys USB 54g adapter (v.4.) on my computer, which works fine with no encryption configured. I can't connect with WPA2. This is Fedora 11, using NetworkManager, with all the latest updates. I get prompted for the WPA2 (personal, not enterprise) password, and get this in my messages file:

-----

Getting a DHCP address fails.

When I boot using an Ubuntu 8.10 live CD, and enter the same data to the same prompts, I get connected with no problem.

When I connected previously with Fedora 10, using the same hardware, to a newer Linksys router with WPA2, I had no problems.

I don't have another router or network adapter that is compatible with WPA or WPA2 to try, but I'm hoping to be able to test with another adapter in a few days.

I have found a reference on the net to this problem occurring with pre-official releases of 11 (whereas the same hardware had worked on 10), but nothing with regard to subsequent versions of 11.

Any suggestions would be appreciated. Thanks.

Edit: Some additional messages regarding the adapter:

lsusb:

mac80211 174944 2 rt2x00usb,rt2x00lib
cfg80211 51620 2 rt2x00lib,mac80211

I was able to try a newer Linksys usb adapter:

lsusb:
ID 13b1:0020 Linksys WUSB54GC 802.11g Adapter [ralink rt73]

It's working fine with a different driver:

lsmod:

crc_itu_t 1596 1 rt73usb
rt2x00usb 9008 1 rt73usb
rt2x00lib 33340 2 rt73usb,rt2x00usb
input_polldev 3212 1 rt2x00lib
mac80211 174944 2 rt2x00usb,rt2x00lib
cfg80211 51620 2 rt2x00lib,mac80211

That wouldn't surprise me if the older model hadn't been working before.

Heya,

First of all, I am quite new in Linux, so please forgive me if I write unuseful stuff (I hope not).

What kernel do you use? I tried the whole day to run the linksys WUSB54GC and no solution in the net was working. Just a couple of minutes I read the release history of the Ralink RT73 driver, which can be found beyond this crypic link:
http://www.ralinktech.com/download.p...hNVEF6Qw%3D%3D
and there is written:

[V 1.1.0.3] (actual version)
1.) Support kernel 2.6.29.

I am running under 2.6.30, what may be a reason why I cannot use the WUSB54GC. If you use another driver for your adapter WUSB54G, you should check (http://www.ralinktech.com/support.php?s=2), if your kernel is supported.


Greetings,

NothingSpecial

P.S.: If you use the 2.6.30 kernel as well, can you give me a hint, how to install the WUSB54GC?

I was using whatever the latest update kernel to fedora11 was on the date I posted. But I had no problems with the GC. I just plugged it in and it worked. It's the large-format external Linksys USB adapter that I can't use. Also, everything is fine except when I try to use WPA. Used to work with my adapter; now it doesn't (or didn't as of a couple of weeks ago.)

I've updated to Fedora 12. No improvement. Ubuntu works properly with the same hardware.

Have you installed the wpa_supplicant package?
