I'm running 12.04. Although my wireless connection is performing perfectly well, the Wireless signal strength indicator shows a low signal. Only the bottom bar is illuminated, whereas with Ubuntu 11.10, the indicator was fully lit up.

My wireless card is USB, and lsusb output is:

 Bus 002 Device 004: ID 148f:3072 Ralink Technology, Corp. RT3072 Wireless Adapter 

How can I solve this?


check signal with wicd, sometimes network-manager say crazy things like this, but I suggest both wicd and network-manager.

sudo apt-get install wicd
