Since my upgrade to Lucid, I have been experiencing dropouts on my wireless connection and since the solutions that I had found on the net did not solve the above problem, I decide to script a temporary fix until it gets fixed in (K)Ubuntu or in the Kernel.

I found that that after I get disconnected if I were to disable wireless or sometimes disconnect and then try to (enable wireless &) connect again I am connected for a random amount of time. I automated this by writing a bash script to check for connectivity to the net and try to reconnect if there is no connection.

This has worked well for me so far and if your are experiencing similar issues, give it a try. The script is available here.

Update: Looks like the wireless dropout issue has been been fixed in Lucid 🙂
