First of all: No problems with sys-apps/baselayout-1.11.15-r3.

If i comment out that line the problem still exists. cat /sys/class/net/ath0/carrier works, will be "1" if association succeeds. Looks like a racecondition, if i execute the logged commands by hand, the association works.... A "watch --interval 1 iwconfig ath0" shows that sometimes the card associates to the ap during scan. But this association drops immediatly, if the scripts calls iwlist ath0 scan (or one of the commands direct behind), and will never come back. I can see the freq changes, it stops at 2.412GHz, but not accociated. Now i'm lost. Some ideas?
Created an attachment (id=94078) [edit] emerge --info
What's about creating a similar entry (!net.wlan0) in /etc/conf.d/net as described here : https://bugs.gentoo.org/show_bug.cgi?id=143666#add_comment
I think I'm seeing this too. I'm using madwifi-ng-0.9.2 and baselayout-1.12.4-r2. my /etc/conf.d/wireless: key_atropa="xxxx-xxxx-xxxx-xxxx-xxxx-xxxx-xx enc open" dhcpcd_atropa="-t 16" config_atropa=( "dhcp" ) #dhcpcd_ath0="-t 16" #config_ath0="dhcp" preferred_aps=( "atropa" ) associate_order="preferredonly" results in: aconite conf.d # /etc/init.d/net.ath0 restart * Starting ath0 * Configuring wireless network for ath0 * Couldn't associate with any access points on ath0 * Failed to configure wireless for ath0 But everything in iwconfig ath0 looks setup correctly. I can manually "dhcpcd ath0" and it connects (in other words, essid, WEP key etc are setup correctly by the baselayout script). Its just the baselayout script that won't connect to an AP, everything works if I do it manually. I don't really understand Comment #2's reference to bug #143666 because this doesn't seem to be anything to do with *PLUG...

Created an attachment (id=94150) [edit] Fix frequency detection This should fix the "iwconfig ath0 freq 2.412 GHz (Channel 1)" bug as described above. Please test and report back. I have a madwifi card, but it powers my AP. I'll see if I can replicate it in the week when I can get a keyboard and screen to it, otherwise I'll happily review any patches that come in.
Created an attachment (id=94182) [edit] if_down_up_hack.patch Ok, found it. The new baselayout misses two lines of code: @@ -486,6 +496,10 @@ esac done < <(iwlist "${iface}" scan 2>/dev/null) + # HUP the interface as some drivers/cards need it + interface_down ${iface} + interface_up ${iface} + if ${error}; then ewarn "${iface} does not support scanning" x="adhoc_essid_${ifvar}" It is of curse a dirty hack, but madwifi need it. Try something like this: ~# iwlist ath0 scan ; iwconfig ath0 essid net4u2 with an up interface (assiociated or not). That will sussessful stop any assiociation and will _not_ reassiociate to any ap. There is a problem in the madwifi-driver... maybe this one?: http://madwifi.org/changeset/1665 Another problem, that is hidden with this down/up hack: Before scanning the script does: # Set the essid to any. This is required for scanning iwconfig "${iface}" essid any veinfo "Scanning for access points" Now the essid is any, an if you have a longer scan_time set the card may already associate to the ap ANY during the scan sleep;) If the scan is finished, the script sets the essid and checks immediatly for a valid association. This is racy: Sometimes he finds the old one, and then the rest of the script is a little bit confused.... It wold be a good idea to inhibit a association during scan (but how?). The call to preassociate() is maybe also wrong: It is called after iwconfig "${iface}" essid "${ESSID}" With a fast card (never have seen one :) the association may already has done. The patch in the attachment is including the freq-patch (yes, it works)

The bad news is that whilst madwifi needs it, it breaks rt2500 and some versions of acx100. So that's not going to fly right now - it's going to have to be fixed upstream. >There is a problem in the madwifi-driver... maybe this one?: > >http://madwifi.org/changeset/1665 That patch is in 0.9.2 - or are you saying this breaks it? > Another problem, that is hidden with this down/up hack: > > Before scanning the script does: > > # Set the essid to any.

But the comment states, that there are still problems;) And yes, i dont like the down/up-hack. If someone can confirm the weird behavior of the madwifi driver after scan a bugreport upstream is the right bug fix. > > Again, that is something that most other drivers require - as the essid has to > be set to ANY or they will not rescan successfully and just use the last scan > list prior to association. > The easiest way to fix this is in iwconfig_wait_for_association(). Reverse the lines: while true; do iwconfig_test_associated "${iface}" && return 0 sleep 1 and the race is almost gone. (wait for at least 1sec)
As per comment #4, commenting out the "# Use sysfs if we can" block of code had no effect, still doesn't work. aconite ~ # iwlist ath0 scan ath0 Scan completed : Cell 01 - Address: 00:0C:41:1A:82:A0 ESSID:"REDSCAPE1" Mode:Master Frequency:2.437 GHz (Channel 6) Quality=24/94 Signal level=-71 dBm Noise level=-95 dBm Encryption key:on Bit Rates:1 Mb/s; 2 Mb/s; 5.5 Mb/s; 11 Mb/s Extra:bcn_int=100 Cell 02 - Address: 00:14:BF:38:CA:3B ESSID:"atropa" Mode:Master Frequency:2.462 GHz (Channel 11) Quality=38/94 Signal level=-57 dBm Noise level=-95 dBm Encryption key:on Bit Rates:1 Mb/s; 2 Mb/s; 5.5 Mb/s; 11 Mb/s; 18 Mb/s 24 Mb/s; 36 Mb/s; 54 Mb/s; 6 Mb/s; 9 Mb/s 12 Mb/s; 48 Mb/s Extra:bcn_int=100 Cell 03 - Address: 00:0F:3D:BB:46:70 ESSID:"martin" Mode:Master Frequency:2.437 GHz (Channel 6) Quality=1/94 Signal level=-94 dBm Noise level=-95 dBm Encryption key:on Bit Rates:1 Mb/s; 2 Mb/s; 5.5 Mb/s; 11 Mb/s; 22 Mb/s Extra:bcn_int=100 Re comment #5: I don't see the channel bug so I can't test. Re comment #6: I can confirm this: ~# iwlist ath0 scan ; iwconfig ath0 essid atropa causes it to not associate with my AP Also, the up/down "fix" indeed works for me, will use that until something better comes along. Re comment #8: switching the sleep 1 and the iwconfig_test_... line doesn't fix anything for me.
Does this help any? Place it in /etc/conf.d/net preup() { if [[ ${IFACE} == "ath0" ]] ; then # Some atheros cards need an extra up # NOTE: the card is upped a few times anyway, so this *should* be redundant interface_up "${IFACE}" # Maybe give it time to settle sleep 2 fi }
I see similar behaviour since the update to baselayout-1.12.4-r2 (updating to -r3 did not change this); the preup() function (comment #10) does not help at all. * Starting ath0 * Running preup function [ ok ] * Starting wpa_supplicant on ath0 ... [ ok ] * Starting wpa_cli on ath0 ...

Upgrade to baselayout-1.12.4-r3 didn't help.

(In reply to comment #13) > Is there still an issue here to report upstream? Yes. The issue is that people have two similar issues with madwifi - one fix requires that preup code and the other requires that interface down/up hack. Some people need one or the other - I know of one person who requires both. The odd thing is that my atheros based (early card works quite happily without either, so I'm guessing that it's a driver/hardware issue. FWIW it's a NetGear WG311v1 - Atheros Communications, Inc. AR5212 802.11abg NIC (rev 01) Someone should report this upstream and reference it here. I'd appreciate that as my card is also my AP in a headless server making testing/debugging difficult at best - also I don't seem to suffer from the bug.
Ok, I submitted this ticket to upstream madwifi: http://madwifi.org/ticket/823 Anyone who understands the issue more than I, please post relevant info there.
(In reply to comment #15) > Ok, I submitted this ticket to upstream madwifi: > http://madwifi.org/ticket/823 Thanks. I'm going to close this bug as upstream. Re-open / comment if upstream changes status on it. BTW, don't emerge dhcpcd with the debug USE flag - it won't actually work as a dhcp client ;)
Here in the office i can't reproduce it with the gentoo scripts, they just work... So maybe the problem depends on the ap's flying around in the air.

Re comment #16: I don't have debug USE flag on, I just pass -d to dhcpcd in (dhcpcd_atropa="-d -t 16"). Its a habit I got into on my laptop trying to connect to weak APs: I can see whats going on a bit better instead of just waiting for it to timeout. I don't think its affects dhcpcd's functionality.

This ist complety _wrong_. The fix is http://madwifi.org/ticket/776 Try to reboot after applying the patch, un/load the modules may not fix it ;) Attached the shortes patch found to resolve the gentoo-script problem.
Comment #21: removing preempt_scan does seem to avoid/fix the problem, will report upstream.
Hmmm on second thought, while removing preempt_scan does seem to fix the gentoo issue in this bug, it doesn't seem to have any effect on my upstream but at http://madwifi.org/ticket/823. Maybe these are two seperate issues.
