Description

barabashka 2008-12-25 03:32:38 MSK

При использовании NetworkManager'а происходит пропадание пакетов на интерфейсе с переодичностью 5-10 пакетов на 100.

В /var/log/messages есть сообщения от NM после установки соединения? Если есть - покажите.

В messages нет ничего, на 12 консоли появляются с некой переодичностью

lost-wifi-adhoc-messages

Не знаю, имеет ли это отношение: у меня на iwl3945 с одной стороны (и iopw2200 с другой) в ad-hoc сети теряется 37% пакетов, при этом пишется куча сообщений на стороне iwl3945:

kernel: wlan0: Configured IBSS beacon template
kernel: phy0: Adding new IBSS station ....

(дальше MAC или что-то подобное)

несколько штук в секунду. Я подозреваю, что при такой интенсивности сообщений оно нормально работать не сможет.

Остальные сообщения, которые попали в /var/log/messages, приложены.

попробуйте сравнить вывод iwconfig в обоих случаях, может наведёт на какие-то мысли.

Это тоже только при использовании NM?

NetworkManager: <WARN>  scan_results_cb(): could not get scan results: An error ocurred getting scan results..

wpa_supplicant вместо результатов сканирования по каким-то причинам прислал эту ошибку. Похоже в этом случае все-таки баг не NM.

Есть шанс, что NetworkManager-0.7.0-alt17 может помочь.

Нет, получается, это не только при использовании NM: https://bugzilla.altlinux.org/show_bug.cgi?id=21962 (там без NM), так что это не связанная с этим проблема.
