I installed the update and my wireless disappeared. I rebooted and the wireless still did not work. I tried an ethernet cable and I got an internet connection but no panel icon.
I re-installed all necessary packages and rebooted. The wireless icon was replaced by a box with a red "no access" type sign. I clicked on that and got a wireless connection back. The dodgy looking icon is still there
