3G USB Modem does not connect

Hello, I have tried 3 different USB Modems with XG85 and while the FW recognises the modem, and I have done all the configuration (APN, SIM Code etc), when I press connect, it stuck in "connecting" while doing nothing.

The modems that I have tried are the following:

Huawei K3770

Huawei K3806

ZTE K5008-Z

Does anyone have made it to work?

I have a different Huawei model - E3131-s2 - and it works, well mostly. It connects but SFOS complains about the connection. It is always "red" in WAN Traffic Manager.

And BTW I am using SFOS on custom build miniPC.

The reason for the Red on the WAN manager is because the 4G/3G because the interface tries to reach 128.0.0.1 to probe for the dead gateway detection. change it to 8.8.8.8

Unfortunately, this is one step beyond the problem. The USB modem does not even connect, neither as "backup" connection, nor as "active" connection with load balancing...

Isn't it a bug ? Ethernet WAN does not have this problem and on the other hand WWAN correctly reports IP, default gateway, etc.

Well, My 3G interface shows 128.0.0.1 only in "not connected" state. After I click "Connect" it shows gateway 10.64.64.64 and an IP from private space. My 3G provider is T-Mobile and my plan does not qualify for public IP.

I'm not sure if changing the gateway is there right thing to do. Wouldn't it break connection?

Unfortunatelly, mine is stuck when I press the "connect" button. It says connecting for about 30sec and then goes back to "disconnected".

Are you sure the modem is compatible with Linux ? Have you tried it in any popular Linux distribution? If it works out of the box in Ubuntu - there is a chance it will in any other Linux-based OS.

BTW: Could you please post your modem setup from SFOS WWAN configuration page ?

Ok, i finally solved "red status" of 3G connection. After enabling WWAN and connecting a modem, WAN gateway object is created @ System -> Network -> WAN Link Manager. By default, Failover rule tries to ping gateway. My carrier blocks pings to default gateway. I have changed the host used in failover rule from default gateway to Google's DNS (8.8.8.8) - and now WAN gateway status is green.
