Two simple shell scripts to turn wifi on or off. At one point I was just clicking on desktop links to these but eventually found it was easier to do it from the task bar. They simply run iwconfig to flip txpower on the wlan wifi adapter. wifiOff.sh sudo iwconfig wlan0 txpower off echo "Wifi is Off" iwconfig sleep 10 wifiOn.sh sudo iwconfig wlan0 txpower auto echo "Wifi is Off" iwconfig sleep 10 If you run iwconfig without arguments, it will tell you what your wifi looks like wlan0 IEEE 802.11 ESSID:"YOUR-WIFI-ROUTER-ID" Mode:Managed Frequency:2.462 GHz Access Point: ##:##:##:## Bit Rate=72.2 Mb/s Tx-Power=31 dBm Retry short limit:7 RTS thr:off Fragment thr:off Power Management:on Link Quality=45/70 Signal level=-65 dBm Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:3 Invalid misc:0 Missed beacon:0 eth0 no wireless extensions. lo no wireless extensions.
