Qualcomm atheros ar9462 driver linux

Немогу добиться работы bluetooth от AR9462

Всем привет, есть Acer c720p с чудо железкой «Qualcomm Atheros AR9462 Wireless Network Adapter» на которой уживается и wifi и bluetooth (вот жеж жесть).

Не могу завести на ней bluetooth.
Собирал модулем и загнал в /etc/modprobe.d/ath9k.conf

options ath9k btcoex_enable=1 bt_ant_diversity=1 ps_enable=0 

И даже пытался делать modprobe -r ath9k; modprobe ath9k btcoex_enable=1 — по нулям. Вот что после этих манипуляций в lsusb

Atheros AR9462 WiFI очень нестабилен и потеря пакетов

У меня серьезные проблемы с потерей пакетов и вообще плохое соединение с Wi-Fi в моей сети. Я обычно сталкиваюсь с потерей пакетов ~ 50% и прерыванием соединений, что делает невозможной работу с SaaS.

Я использую Ubuntu 13.04 и мой сетевой адаптер — Atheros AR9462.

Применение опции nohwcrypt = 1 ничего не меняет.

Также очень заметно: соединение работает, как и предполагалось в других сетях; проблемная сеть использует WPA2 с MSCHAPv2.

Кто-нибудь может помочь мне здесь?

nohwcrypt = 1 Вариант , что вы имеете в виду это от этого ? Просто чтобы уточнить, вы точно следовали этому ? (то есть вы набрали options ath9k nohwcrypt=1 в /etc/modprobe.d/ath9k.conf

Я также слышал, что отключение ipv6 решает проблему отсюда . Если это не сработает, попробуйте это Прочитайте пост, который начинается с: This driver compiled on the kernel you are using with no errors or warning. Install linux-headers-generic for your kernel version and build-essentials then: Please download compat-wireless-3.6.8-1 from the link below.

Моя карта ath9k не страдает от аппаратной криптографической ошибки, но имеет ужасную силу сигнала. Просто о чем стоит подумать. Он работает в ASUS, и работает хорошо, как я и ожидал, но уровень сигнала, который я получаю, по сравнению с некоторыми другими ноутбуками / беспроводными устройствами немного ниже . Я просто говорю, не исключаю сигнал прочность и отсутствие внешней антенны или встроенного антенного кольца.

У меня была эта проблема с Acer Aspire V5 с AR9462. Ни одно из предложенных исправлений не сработало. Я, наконец, получил Wi-Fi, работающий отлично, изменив настройки на моем модеме. Я изменил полосу пропускания с 20/40 МГц до всего 20 МГц.

Arch Linux

Hello, I have been trying to install Arch on a Dell Latitude 3570 with a Qualcomm Atheros AR9462 wireless card. I have successfully installed the OS, but when I boot from the disk I cannot connect to wifi using iwd. When I boot into the live environment, mount my root partition, and chroot in I can connect to wireless just fine using iwd. I am unsure why it does not work when booting off the disk. I have linux-firmware installed, and lspci -k output is below. I am unsure of what the hang up here is, does anyone know what is causing this? Thank you for your time!

Re: [SOLVED] Qualcomm Atheros AR9462 Wireless not working

What does «not work» mean exactly? Is the device not visible/is the device visible but establishing the connection fails?

After an attempt to connect, post a full journal

Re: [SOLVED] Qualcomm Atheros AR9462 Wireless not working

Sorry, I should have been more detailed. When I run iwd I am able to scan and see the network, and the station connect command seemingly works with no error. I would then quit iwd and try to ping a website (e.g. ping -c 5 archlinux.org) it would give me an error message. I just went to try and reproduce it, but in the interim time since I last posted I installed a desktop environment and now when I try and connect to the network to iwd it simply says «operation failed.»

Pastebin output of sudo journalctl -b is here

Thank you for trying to help me!

Re: [SOLVED] Qualcomm Atheros AR9462 Wireless not working

It seems you’re using NetworkManager?
I think that conflicts with iwd, so try to stop the iwd.service, and connect with nmtui or another front-end.

This is what was wrong! I followed these steps and this worked. Thank you so much for your help, I will do a better job of reading the documentation and understanding the tools I am using from now on!
