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?
