USB LTE modem - E3372

[paulh]

Has anyone ha any luck getting a Huawei E3372 stick working on Opnsense?

I am looking for a simple 4G modem to get working, but this doesn't seem to want to talk to Opnsense.

E3372s works:

Thanks for the link.

I’ve tried it but I’m getting the following error in the logs:

   ppp: [wan_link0] MODEM: chat script failed
   ppp: [wan_link0] CHAT: The modem is not responding to "AT" at ModemCmd: label.

Hmmm, is it an E3372h or an E3372s ;-)

This is the unit I am using, which said it supports PPP / Linux, rather than the hilink version which I assume was the h model:

Huawei Unlocked E3372-153 LTE/4G 150 Mbps USB Dongle (Black) - Serial Port Version (PPP) for use in Router systems/Raspberry Pi (Non-HiLink) Full Linux compatbility (Renewed) https://www.amazon.co.uk/dp/B07KB2MKCW/ref=cm_sw_r_cp_api_i_crFWCbRG6M0NY

See the frustrated customers over at Amazon, it's apparently a 3372h.

I would stick it into a Windows machine and get it up and running, will download latest firmware. Try again, you will need to find your own recipe with AT etc... Startpage is your friend. Try rebooting the sense more often than not after changing any parameters.

Have you tried changing /dev/cua? Try each one of them until your modem can connect properly.

Thanks for your replies... I ended up having to get a Netgear LB2120, put it in bridge mode via ethernet and that worked without an issue. (spent too much time with no success on the dongle that I had to cut my losses    )

Hi,

I don't want to create new topic, so I put it here.
I have similar problem with Huawei e3372h in OPNsense 19.1.4-amd64
I'm still getting:

Code: [Select]

CHAT: The modem is not responding to "AT" at ModemCmd: label.
I have modem in "stick" mode.
I've updated init string with: "&F&C1&D2E0S0=0", also "Z", "F" or empty.
It looks like init string wasn't changed and used in new configuration.
I've changed init string in PFSense with "&F&C1&D2E0S0=0" and it started working.
Any ideas?

Anybody had similar problem?
