I'm a fan of tomatousb Shibby (great work, man), and have been using it for a very long time on my Asus RT-N66U with a wired connection. Recently, I've bought a new RT-AC68U, and moved the old N66U outside of the city to a place where the only affordable option to connect to internet is via a 3g modem. The modem I have is Huawei EC 306. To avoid hassle with mode switching, I issued AT commands for the modem to function as modem-only. All three usb tty's (0,1,2) are the serial modem now, and I tried them all (as well as the others) in the respective settings tab, but to no avail. pppd just won't establish connection. I flashed dd-wrt then, and it connects just fine, and the connection is more or less stable, but I like tomatousb a lot more…
Here are the logs:
If there's a way I can get some additional info, please tell me, and I'll try to do that when I have the chance.
