I have the same problem. I tried to install network-manager on Edgy some times ago and sometimes the icon would appear in the tray, sometimes it wouldn't.
I recently installed Feisty Fawn on a different partition and the same bug occurs. Just after the installation the icon was there, it would scan wireless networks and I was able to configure my connection. Now, most of the time, it doesn't appear anymore. I have to use the usual network managing tool in System>Administration. My laptop is an Acer Aspire 1525WLMi. It has an integrated wifi card which can be used with ndiswrapper but I'm using a pcmcia wifi card, a D-Link DWL-G650, which is supported by default in Edgy and Feisty. -- nm-applet - No Icon in Tray - No Response at all https://launchpad.net/bugs/84146 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
