My new Surf SOHO Mk3 (AC) just came in and I eagerly followed the guidance here (http://www.evdoinfo.com/content/view/4384/63/) to connect to my AC791L via USB. No dice. After a restart, and logging in to 10.0.0.1 (the new IP address for the SOHO), enabling USB tethering on the 791L, and moving the USB connection to the first priority in the WAN, the connection cycles between nothing, and “device detected” and then “connected” then…nothing again. But sometimes it goes to “unknown physical status” for a while before going back to nothing. And sometimes it goes straight from “device detected” to nothing.
Firmware is 6.3.3 build 1068, modem support version is 1019. AC791L is software version 02.08.59.00
Help? I’d like to get this setup working…only internet I have.
