Internet access via 4G Dongle using RNDIS

B

balanga

A few years ago, I remember having a hard time getting a 4G Dongle (Huawei E3372) to work accessing the Internet, but recently stumbled on it and thought I'd try again.

I was suprised how straight forward it was to get going under OpenWrt using rndis. Now I'm trying to do the same on FreeBSD, but am unsure of how to use RNDIS.

kldstat shows if_urndis.ko, so what else do I need to make the USB dongle access the Internet?
 
The urndis driver loaded automatically after connecting dongle to computer?
What ifconfig shows?

I haven't any 4G/3G dongle.
 
When I plug in the dongle it shows up in usbconfig() like so:
ugen0.2: <HUAWEIMOBILE HUAWEIMOBILE> at usbus0, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=ON (2mA

lsusb() shows:
Bus /dev/usb Device /dev/ugen0.2: ID 12d1:1506 Huawei Technologies Co., Ltd. Modem/Networkcard

It connects OK when I use it in OpenWrt.

Anyone know what could be missing?
 
do you have a serial connection to the modem also ?
you can use cu + AT commands to check network status and stuff
 
I have this if this is what you mean:-

I tried to use USB tethering via my phone and got an IP addressed established

Code: 
ue2: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
        ether 02:0b:36:32:3b:65

        nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL>

How do I access the Internet using this interface?

Is it just a matter of setting defaultrouter?
 
I use this dongle to send notifications to my phone via sms. This is how I use.

When connected to the server run this script:

As you can see you need usb_modeswitch.

Code: 
#!/bin/sh

/usr/local/sbin/usb_modeswitch -v 0x12d1 -p 0x1f01 -c /usr/local/share/usb_modeswitch/12d1:1f01

sleep 5

ifconfig ue0 inet 192.168.8.10/24
#dhclient ue0
#dhclient -b ue0

sleep 3

setfib 1 route add -net 192.168.8.0/24 -iface ue0
setfib 1 route add default 192.168.8.1

sleep 2

I remember I had the no-carrier status until I run the first script in my reply above.

I think starting FreeBSD 14 the modem switches mode auto, but still needed to run the above script. I didn't have time to modify any part of the above scripts as it just works anyway.

You may have needed to run modeswitch to modify your dongle. Apparently there are two versions, hilink and stick.

I was told on another forum that I didn't need to run modeswitch and I managed to access the Internet without doing so.

I'd be interested to know which mode your dongle is in. Mine is defined as a modem/networkcard rather than as a storage device.
