Bug Description

I'm using Ubuntu 12.04 on Toshiba AC100 (ARM).

network-manager 0.9.4.0-0ubuntu4.1
network-manager-gnome 0.9.4.1-0ubuntu2

It often happens that whenever I want to connect to another WiFi network through the menu of the applet, there is no reaction for very long time (10 mins, or for ever).

I tried to select "Disconnect": no reaction.
I tried to select the new network many times: no reaction.

Workaround (as root):

service network-manager restart

I've just collected te info once again because now this happened again (before I restarted network-manager and could connect to the other WiFi network).

Am I correct in understanding that the Wi-Fi device in question is a Ralink and the driver is rt2800usb?

Can this bad behavior be understood?
