Wifi /shouldn't/ touch /etc/network/interfaces, usually the only programs that will ever try to alter it are network managers. What procedure did you use when trying to bring up wifi? I've previously used "ifup eth0" from console or terminal, but with newest SHR (Jan31 or so opkg upgrade) there IS NO ETH0 most of the time, resulting in "No such device" errors. Also note that if you've been connecting and disconnecting the FR from the host computer many times since the host was rebooted it may have problems. Initially my usb0 was the third network device (the '3' in the first column above) on my host, but currently it's 12. I've seen it get "too high" before and only a reboot of the host would allow it to connect again. (sorry, I don't remember where it started failing - IIRC it was at 32 but don't shoot me if that's way off) I recently encountered the same problem - unplug from USB, power-cycle freerunner & wait for boot to finish, plug in USB, wait 5 secs, unplug USB, wait 5 secs, plug back in, and I had a connection. (I don't know if it's the FR or Ubuntu but if I boot or reboot the FR while attached to USB it usually doesn't connect until unplugged and re-attached, so I'm already used to unplug/wait/replug) If that fails, then reboot the FR, open the terminal on the FR and check the output of "ip a s usb0" - allowing for the randomly-selected MAC address, it should look pretty much like: 3: usb0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast qlen 1000 link/ether 22:7d:18:7d:5a:a8 brd ff:ff:ff:ff:ff:ff inet 192.168.0.202/24 brd 192.168.0.255 scope global usb0 inet6 fe80::207d:18ff:fe7d:5aa8/64 scope link valid_lft forever preferred_lft forever and "ip r" should show you: 192.168.0.0/24 dev usb0 src 192.168.0.202 default via 192.168.0.200 dev usb0 Presuming that's correct, do the same on the host computer, which should at least show interfaces usb0, though it may be down or have no IP address at this point. If it's down, try "ifup usb0" on the host (root or sudo) or "ip l s usb0 up" and take a look at the data again. If the interface is up on the host but has no IP, try "ip a a 192.168.0.200/24 dev usb0" (again, root or sudo) and see if you can connect. j -- Joel Newkirk http://jthinks.com (blog) http://newkirk.us/om (FR stuff) _______________________________________________ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
