I'm trying to make work USB Tethering on my Ubuntu 11.10. Network Manager see the devices but it stay grayed and cannot be selected.
Same problem with iPhone 4 or Galaxy S2.
It used to work under 11.04.
Wifi tethering works great.
Tailing syslog says Network Manager see the device and try to obtain an IP but only in IPv6, no request in IPv4.
What I'm missing ?
Thanks for any help.
