Seirra AirCard 770S as WAN
-
Hello,
I've been using pfsense in the office for about 6 weeks now and so far, so good! We are setting up a pfsense box for another one of our stores and I was curious if anyone has successfully configured a Seirra AirCard 770s as WAN on their box. I've tried my best at google-fu and researching documentation but it hasn't got me far. I'm specifically having trouble setting up the hotspot in PPP settings. My provider is AT&T. Our goal is to use the hotspot as a fail over in case our main ISP goes down. Thanks very much for the help. It's appreciated!

I don't have experience with that particular model but i can say that all the Sierra products seem to work in my testing. Maybe not the newest MC73xx series but all the rest. I only have Aircards and MiniPCIe modules.
I be willing to be it is related to the USB port your device needs. CuaU0.4 was mine. One tip i saw said usually next to last usb interface. That was was did it for me.
I also just setup a MC7700 and it required no special PPP config except for correct port. Which i now know. Now it is a breeze to repeat on any box. So trick is finding your USB port for comms. -
When i look up that model it is an MIFI so your title is misleading as is that model name. How is that an Aircard i dunno…
I really am unsure if you could use this as your wan, but i bet you could. The device hands out IP's via DHCP so that seems good but the carriers limit number of devices allowed with MIFI's so I would expect problems. -
And there would be no need to setup PPP with this. You need to go the WIFI bridge method i think. PPP is for 3G/4G. Your mifi is handling that so you need to make a multi wan setup with wired primary WAN and your 770S Wifi-Bridge as fallback. I believe….Good luck.Keep us posted.

And when i say wireless bridge, i am speaking literally. Not physically. I do not think you need to create a bridged interface in pfsense for this. Just get an Atheros based wifi card of some sort and make the WIFI your WAN 2. You will have to set it to Infrastructure mode and use the sierra MIFI devices SSID as the SSID in your pfsense Wifi interface infrastructure settings so it knows where to connect to…Follow MultiWan instructions from there.

And to boot my advice may be bunk. I just read you could use a usb cable and see the device as a modem on some companies MI-FI's models. So wireless bridge would work but may not be the only way. I wonder if you see a usb ethernet adapter in your assignments. Like ue0 or similar. If so you would need pppoe instead.
