wireless stopped working as of last upgrade [Solved]

bvbellomo · 2010-07-05 15:30:03

I did a sudo pacman -Syu system upgrade and it completely trashed my ability to use wireless. I am typing this on my playstation 3, so please don't ask me to cut/paste lengthy messages.

I used to use a network device ath0. Now it is not in the list, but I have a wlan0, which I am not sure if that was there before or not.

I can modprobe my ath9k driver, which I think I was using, but am not certain. dhcpcd times out.

Please help

use iwconfig to check if wlan0 is indeed a wireless card, scan for wireless AP's, associate and use dhcpcd, use lspci -vv to see if there are any other hardware whose modules aernt in use, dont modprobe, the autoload of modules does that automatically for each device it detects.

I should have posted, but am using a USB wireless, not a PCI card. Also, I am certain my network is working, since that is what the PS3 is connected to.

I don't think an appropriate module is being loaded without modeprobe. I am certain the ath9k driver is not.

wlan0 is showing as a wireless device by iwconfig, but I am certain the device I was using was called ath0.

scanning appears to time out.

lspci -w does not appear to be a valid command.

it is... lspci -vv <- Thoughs are 2 V's for Verbose
But if it is a USB card then I guess try thiss

lsusb -vv

You can use this command to list all the modules that are being loaded.

lsmod

or really run this to just see the mac80211 driver modules that are being loaded for wireless but still look through the full lsmod output because I don't think mac80211 is the manged mode driver?? could be wrong.

lsmod | grep mac80211

Try, this just to make sure wlan0 dose not work but I agree (no that it really means a lot) it seems strange that it is showing wlan0 instead of the Atheros ath0....

ifconfig wlan0 up

iwlist wlan0 scan

My wlan0 device goes away if I boot without the wireless adapter, so I can be reasonably sure this is the right device.

The driver it loads is just called "ath". This driver loads with the adapter plugged in when I boot, but not if I leave the wireless adapter off. I know I was using either the ath5k or ath9k driver, I think the latter, but am not certain if the system decided to switch when I did the upgrade, or if the switch happened months ago and I didn't notice. I tried adding "!ath" to my modules array so it wouldn't load, but it loads anyway. I tried booting without my wireless device, plugging it in, and modprobing the ath9k driver. The ath9k driver loads, but I don't have either an "ath0" or "wlan0" device when I do that.

"ifconfig wlan0 up" runs without producing any output.

"iwlist wlan0 scan" does not find anything, I can post the exact output when I get back home.

I cannot believe I tried a 'w' instead of 'vv'. I feel really stupid, I haven't done stuff like since I started learning to type. I still don't see what good this will do, since I know drivers are loading, I just believe them to be the wrong ones.

I may also have the AR9170 drivers loading, I remember seeing another driver that looked like an Atheros driver, but didn't start with "ath".

I wonder if this is it:

Hum, well sure try that out. If the problem accrued after you installed linux-firmware then give it a shot. Hell give it a shot anyway. It seems all you need to do is...

http://www.kernel.org/pub/linux/kernel/ … /ar9170.fw

2. Manually download ar9170.fw to /lib/firmware

3. Then unplug/plug in dongle -> wireless works fine
There's no need to remove the older firmwares, the driver automatically prefers ar9170.fw.

That was it! I am posting this from my arch box.
