My connection is flaky, however I have a backup one. I made some bash script to check for connectivity and change connection if the present one is dead. Please help me improve them. The scripts almost works, except for not waiting long enough to receive an IP (it cycles to next step in the until loop too quick). Here goes: #!/bin/bash # Invoke this script with paths to your connection specific scripts, for example # ./gotnet.sh ./connection.sh ./connection2.sh until [ -z "$1" ] # Try different connections until we are online... do if eval "ping -c 1 google.com" then echo "we are online!" && break else $1 # Runs (next) connection-script. echo fi shift done echo # Extra line feed. exit 0 And here is an example of the slave scripts: #!/bin/bash ifconfig wlan0 down ifconfig wlan0 up iwconfig wlan0 key 1234567890 iwconfig wlan0 essid example sleep 1 dhclient -1 -nw wlan0 sleep 3 exit 0
