e[sho]ternal usb networking problems

[arne anka]

i do not recall any specific error messages you posted.
but that might be because of the high traffic of this list.
so, please, specify what exactly does not work:
- what exactly are you trying to achieve? connecting your host via wlan to  
inet and accessing inet from your fr through usb to host?
- are you able to connect to your ap? does inet work?
- are you able to connect to/fro your pc via usb?
- did you enable forwarding and do you use different subnets?

please, post the output of
ifconfig -a
of both the host and fr. if you are behind a router (your wlan ap probably  
act as one), there's no need to obscure the ip addresses -- in fact they  
are necessary to narrow down your problem.
