Description of problem: ath5k does not work properly on Alienware M7700 laptop. Version-Release number of selected component (if applicable): Current kernel is kernel-2.6.23-0.164.rc5.fc8, have no had success with prior two kernels either. How reproducible: Boot F8T1 and attempt to use ath5k to connect to wireless network. Steps to Reproduce: 1. Boot laptop 2. Attempt to connect to wireless network using ath5k 3. Try to browse websites Actual results: The driver does enable the adapter to connect to the wireless access point, obtain an ip address, and ping websites by name, however browsing websites is almost impossible. I can get to www.google.com, and some other very small websites, however virtually anything else is inaccessible. Expected results: Should be able to access websites, etc normally. Additional info: The card information (as output from lspci -vv) is: 0a:05.0 Ethernet controller: Atheros Communications, Inc. AR5212 802.11abg NIC (rev 01) Subsystem: Wistron NeWeb Corp.

I actually had no success using madwifi-ng-current snapshot from 2007-09-03; results were similar although I was unable to ping websites, etc. If I did not specify a static IP address the connection would fail after the dhcp client timed out. madwifi-ng-current snapshot from 2007-08-29 works well, or at least appears to. I can access all network resources I've tried connecting to normally.
FWIW, it sounds like ath5k is working better for you than for most...
kernel-2.6.23-0.212.rc8.git2.fc8 contains some ath5k updates. Can you replicate with that kernel?
If anything it is worse, after a long pause it picks up an IP Address but it then attempts to ping the gateway, gets the error message 4 packets transmitted, 0 received, +1 errors, 100% packet loss, time 3011ms, pipe 4 External network device wlan0 is not ready. Aboring.. failed. and of course after that the interface is down. Once again using the madwifi-ng driver all I do is 'sudo make clean && sudo make && sudo make install', change modprobe.conf to read from 'alias wlan0 ath5k' to 'alias wlan0 ath_pci' I also have to rename the ath5k module to something like ath5k.bak, because regardless of what modprobe.conf says it tries to load the ath5k driver rather than ath_pci at boot. Not sure why, but it doesn't seem right... After those three steps everything works as expected (using madwifi-ng)
I have a Thinkpad T40 with Atheros AR5211. I've noticed that ath5k [from fredora kernel] never worked - but madwifi-0.9.3.2 - compiled from sources, always worked. This is with 'ifup ath0' - and not NetworkManager. I've checked with a bunch of rawhide kernels [perhaps over the past 2-3 weeks - but not since FC8T3 was released] Perhaps this is the same issue - hence monitoring this bugzilla.
Additional Notes: Current kernel I have is 2.6.23-0.217.rc9.git1.fc8 I just tried without encryption [ a different network] - and 'ifup ath0' succeeds. However 'NetworkMonitor applet' says signal strength is 0%. iwconfig gives: Link Signal level=36/127 Madwifi - for the same netowrk [where 'NetworkMonitor shows proper signal] gives: Link Quality=27/70 Signal level=-71 dBm Noise level=-98 dBm The network where I have constant problem with ath5k connecting is my home network - with a 64bit WEP key
If you have the ath_info binary from the madwifi package, it may be worthwhile for you to post the information it provides. IIRC, you have to run lspci first to determine the base address assigned to your card by the BIOS, then pass that as an argument to ath_info.
Looks like ath_info is in the svn copy - not 0.9.3.2. I've updated madwifi to svn for now. I'm not sure if I'm doing this incorrectly. I get: # lspci |grep Ath 02:02.0 Ethernet controller: Atheros Communications, Inc.

kernel-2.6.23-0.220.rc9.git2.fc8 is back to the previous behaviour: 4 packets transmitted, 0 received, +1 errors, 100% packet loss, time 3011ms, pipe 4 External network device wlan0 is not ready. Aboring.. failed.
There are some ath5k updates in the kernels here: http://koji.fedoraproject.org/koji/buildinfo?buildID=21169 YMMV, I get an (apparently) different oops now... Do these kernels make a difference for you?
Created attachment 230681 [details] /var/log/messages entries after 'modproble ath5k'
Sorry - my previous message was incomplete. The previously attached log is with kernel-2.6.23.1-16.fc8. Here 'ifup ath0' continues to not work with ath5k driver [wep 64bit, dhcp]. However it works fine with madwifi-0.9.3.2
FYI, info on how to help the ath5k reverse engineering team: http://marc.info/?l=linux-wireless&m=119282415503974&w=2
Please try the kernels here: http://koji.fedoraproject.org/koji/buildinfo?buildID=23734 Are these working any better for you?
On my Aspire notebook, I don't get any errors and there is now a wlan0 interface where there wasn't one before. But NM doesn't see any wireless networks...
No change for me. i.e - WEP64 does not work. - no-encryption works[with 'NetworkMonitor applet' showing no signal strenth]
Good news. I just tried 2.6.23.9-78.fc8 from http://koji.fedoraproject.org/koji/buildinfo?buildID=26543 WEP64 finally works with ath5k [with my limited testing] However 'NetworkMonitor applet' continues to show no signal strength [Note: I'm not using NetworkManager]
I still have problems with ath5k & kernel-2.6.23.9-78.fc8] When I move from a WEP64 network to encryption=off network. it stops working. [i.e 'ifup wifi0' fails]. I've tried the following: - reload ath5k module - same behavior - reboot- same behavior - reboot to 2.6.23.8-63.fc8 - same behavior - unload ath5k and load ath_pci [in 2.6.23.8-63.fc8], now it works! - unload ath_pci and load ath5k [still in 2.6.23.8-63.fc8] - it works! - reboot to 2.6.23.9-78.fc8 - it works! This happened twice [yesterday, and now today]. I guess I should stay with madwifi for some more time. BTW: wrt "nm-applet not showing signal strength with ath5k", should I file a different bug report? [I'm guessing this is a problem with ath5k driver - as this applet works fine with madwifi]
Satish - Yes, please file a separate bug report on the signal strength problem in nm-applet. Also, can you please try a later kernel?
Ok - I've retried with kernel-2.6.23.14-111.fc8 - The problem with moving between networks persist [between WEP64 and encryption=off]. I was able to reset the behavior by either booting into windows - or loading madwifi [rebooting with ath5k didn't help] Wrt nm-applet - its behaving better. i.e, I'm able to see the signal strength properly now. However there is still one issue. When the network is down, [with ifdown wifi0] - it still shows signal strength [with the a red x indicating that the network is down though]. I don't know if this is acceptable behavior. With madwifi - the signal strength is 0 after 'ifdown ath0' iwconfig-after-ifdown-ath0: Link Quality=0/70 Signal level=-98 dBm Noise level=-98 dBm iwconfig-after-ifdown-wifi0: Link Quality=54/100 Signal level=-63 dBm Noise level=-98 dBm Because of the first issue [unable to switching between networks], ath5k is still unusable to me. I'll continue to use madwifi.
Does the "moving between networks" issue happen when using manual configuration (i.e. iwconfig, iwlist, etc) too? Or only with NetworkManager? The ath5k driver should be using software encryption (i.e. done at the CPU, not on the card itself), so it doesn't make much sense that the problem should survive a reboot.
I primarily use ifup/ifdown with /etc/sysconfig/network-scripts/ifcfg-ath0,ifcfg-wifi0 config files [And I haven't used NM in a while because it didn't work predictably for me - when I tried using it.] Wrt reboot not resetting settings - I'm guessing that its not the enc-settings per-say - but some bad state the hardware goes into or something. So far I tried switching between 'wep64-> enc-off' and 'enc-off -> wep-64'. Both failed. [I tried reboot/winxp reset only between 'wep64-> enc-off' transition]. However I suspect the problem might be there when switching between any two networks - irrespective of encryption. [I don't have access to enough networks to try...] Perhaps someone else with a Thinkpad T40 [with atheros] can try reproducing this problem.
Could you attach the contents of your ifcfg-* files? Feel free to obscure your WEP keys as you desire.

Stephen, I have copied the information from comment 27 to bug 254192 comment 96. Please direct your attention there...thanks!
OK, it's been a while...is this still a problem with current F8 (or F9) kernels?
I've upgraded to a machine with intel 3945ABG - so I can't test this anymore..
I've been trying F8 updates, with no joy. Just tried F9 and it works! At least, it does for a simple unencrypted connection. Progress!
Are current kernels working to your satisfaction?
Closed due to lack of response...
