WAN connection over MiFi 6620L using USB tether

Guest

I am not totally sure about this but i have found most of the newer cellular interfaces use a different protocol for interfacing the operating system. It seems they show up as a USB Ethernet device, which is different than in the past, where it was primarily a serial/usb interface which talked with the OS via DirectIP and PPP and now it is an Ethernet Interface. See "CDC-Ethernet".

I believe your device will fall into that category. No interface exists for inputting APN so I don't think it will work currently.

To see if yours is CDC-Ethernet -In pfSense -Do you have an device an Ethernet "UE0" interface or similar in your device list?

Ubuntu would probably work with your device.

I have a verizon 6620. I connected it to my alix apu board and it tries to load it as a mass storage cdrom.

Did you know that only one miniPCIe slot is capable of a modem? It is the one near the SIM card slot.
And also the miniPCIe slot for the mSATA must be the one near the SATA connector!

Maybe you could load usb_modeswitch and eject it…

Did you go into the MiFi devices menu and enable tethering? It may be required.

Did you end up getting this working. The eject cdrom thing is a good step, but they say it has a USB tether mode.

I want to move from the 4620L to the 6620L…any thoughts anyone?

Anyone get the verizon 6620L working in tether mode? I've got latest 2.2.6 PF with Verizon 6620L as a failover wan link. It shows up as cuau0. I put in PPP settings and get this error in the logs.

ppp: [lan_link0] MODEM: Fail to open serial port /dev/cuau0 on speed 115200

Any help is appreciated!

I suspect this port is not suitable for ppp/data and should be used for commands only, similar to Huawei as it was mentioned here.

I ended up just wireless bridging it to pfsense as per usual. It never works very well, but it works. Just have to reboot the device every few days.

I really hate cell service.
