The rt2500 part of this bug appears to be bug 78037. The by-hand fix there works (I need to do "sudo dhclient3 ra0" afterwards, and I have to apply the bug fix again by hand if I unplug the card).
The Netcomm card is actually a Netcomm 11g, and uses the prism54 driver. The same by-hand fix there works for this. Success! So there's a workaround, if not an automatic solution. However, the same problem on different drivers suggests the cause might be at a higher level than the kernel. -- Feisty regression: wifi not working (rt2500, wg54t) https://launchpad.net/bugs/82711 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
