[Bug 461419] Re: [Karmic Lucid] Atheros AR5211 - ath5k driver connection and performance issues
Thinkpad X41 Tablet Installed the compat-wireless package (from end of May). It now takes minutes instead of seconds to connect to the wireless network (and therefore several manual retrials) - error message is simple try1-3 and then timeout. After a few minutes the connection suddenly works usually and then the dmesg output gets really strange with several cfg80211: World regulatory domain updated: - messages, I don't understand and never saw before. The good part is, the connection is stable (at least the applet does not indicate a reconnection) but the connection still comes to a halt sometimes (once or twice a minute usually for a few seconds) - it feels better, anyway, thanks for that work! System-upgrades (like today with open-office-updates) lead to time-outs in the update-GUI nontheless. So still not entirely there but it is finally at least getting a bit better since the connection does not drop out anymore. I attached an example of the dmesg log. ** Attachment added: dmesg-output for x41 tablet ath5k using compat-wireless http://launchpadlibrarian.net/49933381/thinkpadx41t-dmsg-log%20after%20using%20new%20compat-wireless.txt -- [Karmic Lucid] Atheros AR5211 - ath5k driver connection and performance issues https://bugs.launchpad.net/bugs/461419 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 461419] Re: [Karmic Lucid] Atheros AR5211 - ath5k driver connection and performance issues
I have to ask; since the first bug was filed, has there only been one card fixed? Am I the only one finding this absolutely pathetic? Ok, this card that got fixed has seen quite an improvement (I know because I have that card) but what about the other very common card AR5211. That card has been completely broken for years. It barely connects with ath_pci (and of course that driver causes kernel panics) and has been removed from Ubuntu and ath5k doesn't connect at all even with the computer next to the router. Both ath5k and ath_pci are so bad that I even resorted to ndiswrapper, which performed better but caused even more frequent lockups than ath_pci. IBM Thinkpad T40-43 are very common laptops and the fact that AR5211 does not work is quite a bad situation as it's embedded in many of these laptops. Laptops which many people use, after they have bought a new one, to test Linux for the first time. Can anyone answer why there seems to be no work done on that card? Is Atheros not interested in fixing the driver for that card or what? It would be nice to know because then I would know if I should throw that piece of junk AR5211 away and buy an Intel card, or not.

For me, changing to lucid has worsened the performance. The zero-drops of connection speed (and I mean zero) are more frequent (like two times every minute or something like that) and the speed overall is worse as well. Are we supposed to install the lucid backport package? I tried and so far it seems the signal is displayed to be a bit stronger (like 8-10 %) than with pure lucid but the actual performance looks unchanged worse than in karmic with karmic backports -- [Karmic Lucid] Atheros AR5211 - ath5k driver connection and performance issues https://bugs.launchpad.net/bugs/461419 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 461419] Re: [Karmic Lucid] Atheros AR5211 - ath5k driver connection and performance issues
Finaly I think I've found a break through on the problem of certain ThinkPad adapters (MAC:0xa3, PHY: 0x61) recorded in this tread, regarding the issue that they doesn't work with the default ath5k module installed by *buntu. While trying to capture communication between the adapter and a AP, I changed channel of the AP from a high channel to a rather low one. Suddenly I was able to connect and transfer bandwidth was now perfect (above 18 Mbps). After further testing I've found that using channel 1 to 6 on the AP if okay, using channel 7 and 8 was somewhat suspicious, and channel 9 to 13 was unusable. So if you still experience the connection/performance issue and you have configuration access to your AP, you could try changing the channel to one between 1 and 6 (or 2.412 and 2.437 Mhz). This issue only concerns this particular adapter, while other Atheros adapters types I've used do not suffer from this excact issue. Find if your driver is ath5k using : lsmod | grep ath Find if your chipset is MAC:0xa3 and PHY: 0x61 executing : dmesg | grep -i phy Find what frequency in Mhz is used when connected : nm-tool Please let us know if this solved the problem for you - thanks in advance. -- [Karmic Lucid] Atheros AR5211 - ath5k driver connection and performance issues https://bugs.launchpad.net/bugs/461419 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Also, I would like to add that I installed linux-backports-modules- wireless-karmic-generic, but my AR5212 still doesn't work (nm-applet just says 'device not ready'). -- [Karmic Lucid] Atheros AR5211 - ath5k driver connection and performance issues https://bugs.launchpad.net/bugs/461419 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

@Victor You could have a look at Bug #463625, as this is about the exact same ThinkPad adapter you are experiencing problems with: $ sudo lspci -vvnn 03:00.0 Ethernet controller [0200]: Atheros Communications Inc. AR5212 802.11abg NIC [168c:1014] (rev 01) Subsystem: IBM Device [1014:058a] This bug has a upstream kernel bug attached, and I think some backing on both is needed, if this bug should ever be taken serious. Even though bug-description mentions poor connection speed as an issue, latest ubuntu updates or kernels seems to make connections nearly impossible depending on the distance to the AP - if less than 2-3 meters connecting in rear cases is possible, depending on things like the amount of noise from other nearby WiFi networks. -- [Karmic Lucid] Atheros AR5211 - ath5k driver connection and performance issues https://bugs.launchpad.net/bugs/461419 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 461419] Re: [Karmic Lucid] Atheros AR5211 - ath5k driver connection and performance issues
I have filed a bug upstream directly to the kernel, hopefully this will be looked into. You can make comments and track it at http://bugzilla.kernel.org/show_bug.cgi?id=15079 .
