PfSense and Huawei E3276 - 4G

[mjneiva]

I am intending to buy and Huawei E3276 (4G) usb dongle but since it is not listed in the compatibility list (http://doc.pfsense.org/index.php/Known_Working_3G-4G_Modems) I would like to know if someone has some experience with it.

good question  ;)

I have one here for testing as well.

I get stuff like this in the logs:

Still same problem with latest 2.1 stable version.

ATQ0 V1 E1 S0=0
AT^NDISDUP=1,1,"internet"

seems to be what is needed instead (if APN is "internet") to connect the umts/gsm side.

Same modem works on Ubuntu 13.10 (once enabled like this: AT^SETPORT="A1,A2;10,12,13,16"
and unplugged/replugged).

Anyone succeeded making Huawei E3276 4G USB stick work with pfsense ?

Hi,

I am also looking to purchase the Huawei E3276 4G USB stick to install with pfsense. Has anyone got this device working yet?

Thanks

Any ideas why the At command is failing?

[Dan9550]

So i've decided to do a bit of poking around. Using ppp i am able to send commands to the modem (/dev/cuaU1 worked for me). Things like AT, ATZ worked fine. Checking the logs of pfsense after changing my ppp config to use /dev/cuaU1 in the logs pfsense was failing at AT&F&C1&D2E0S0=0M1. I found that running this manually and removing the S0=0 string it worked. After this i wasn't able to do anything further.

You mean that after using a slightly different modem init script you were able to use it to connect? Can you not just enter that as a custom init script?
