Ah, right. I don't really use those scripts myself anymore. I just use the qmicli tool from libqmi. And I assume that works for you as well? I tried the script myself now, and the problem is that it makes a few stupid assumptions. The "usb" class has been renamed to "usbmisc" in linux-next. This breaks the script. You need to modify it accordingly. You really had me worried for a while there :-) > After that dhcpcd says only: > err, wwan0: timed out > warn, wwan0: using IPV4ALL address 169.254.41.53 > > The IPv6-variation of the scripts did not work too. Yeah, I guess you still have to use that script for IPv6 connections. That's not yet supported in libqmi.
