Comment(by olberger):
Here's some bits of diagnosis on the desktop :
# ifconfig -v usb0

You'll notice I have a local LAN with a netmask for 192.168.0.x up to 192
on eth0, but it doesn't seem to be a problem as it works for some time...
Also running tcpdump when it breaks gives :

Will try and provide debug info from the FR if/when I can connect to it
via WIFI at the same time as usb
