Which USB modem are you using?

I want to connect with a Huawei  (E161/E169/E620/E800) HSDPA modem.

Not sure exactly which of these is the correct model but that is whay lsusb tells me.

I'd be very interested in knowing how you got this working.

I'm using FW openwrt-ar71xx-generic-tl-wr703n-v1-squashfs-factory before, and it can't see any usb 3g
but using openwrt-wr703n-v1-GO2017-12-15 everthing is ok, working perfect with USB 3G Sierra Wireless AirCard® 312U 42Mbps

The discussion might have continued from here.
