I’ve got a Huawei 3372h, which I gather works in hostless mode as ‘tethering’. I didn’t too much fancy double NAT-ing so I found a guide here that showed how to flash it into ‘stick’ mode.
Long story short I now have the stick booting up with three serial interfaces, and showing up as a modem on the AR750S. I can send AT commands to it, at least for a while.
The title shows as ‘Test PLMN’, and the ‘dot’ on the front page is orange.
My carrier is Smarty, which runs under three UK.
I have tried this config without much joy. I changed the ttyUSB to USB2, which is what responded to AT commands, and I changed the APN to what Smarty says.
Anyone had any joy getting this to work? I might reflash to hostless if I have no luck.
Not that this helps but I have a couple of similar mifi devices and I just use as a mifi and don’t worry about double Nat but then again I don’t do anything to complicated.
Mifi as 192 168.0.1, gl. Inet router at 192.168.8.1.wifi turned off on the Mifi. I can access both devices seperately if I need to.
OK I’m making some progress. Flashed E3372h-607_Update_21.200.07.00.00, and now I am getting a green dot on the front page, and the logs show the link is up.
That is in conjunction with the settings shown here:
