My Wireless is not running. I tried for the solutions found in the internet. Many solutions had told me to go through some steps and one of the step was to run $ sudo modprobe ath9k, But When I run the code sudo modprobe ath9k following error is displayed.

WARNING: Error inserting ath9k_hw (/lib/modules/3.2.0-40-generic/kernel/drivers/net/wireless/ath/ath9k/ath9k_hw.ko): Invalid argument

are you sure you are using atheros hardware?? Because now a days they don't need manual compilation. Maybe you can edit your question and post result of lspci sudo lshw -c network & rfkill list all so that we can help. Also in addtion link of that tutorial will be great. –  Web-E Apr 18 '13 at 8:00
