wireless networks not detected

Hi. New to Mint and am having trouble getting wireless to work consistently/reliably. Toshiba laptop with Atheros AR5007EG wireless device. Running Mint 13 Mate.

Here is the result of running the command requested by the wireless forum:

Here is the results of running: lspci -nnk | grep -A2 net as requested by caf4926.

I think you need to look at
http://madwifi-project.org/

ath5k will need blacklisting


You may need to check if you have HAL
As it has been dropped in some cases

Perhaps wait for other advices.

Try in a terminal

Code: Select all

sudo ifconfig wlan0 down
sudo rmmod -r ath5k
sudo modprobe ath5k nohwcrypt=1
sudo ifconfig wlan0 up

If that works then to make it permanent do

Code: Select all

echo "options ath5k nohwcrypt=1" | sudo tee /etc/modprobe.d/ath5k.conf

Read some of the madwifi literature. not sure what I should do next though. sounds like linux has issues with my Atheros card, and no good solutions yet? If someone knows of a work around I can follow step by step instructions. Thanks, ronb.

wireless is operating as it should, at least for the moment. as soon as it fails to pick up wireless next time I will try the steps suggested by remoulder. it works in spurts with no rhyme or reason i can see.

I have the same problem and this command gave me:
