3G modem huawei E352 works only for a week
-
I'm running 2.3.1-RELEASE-p5 (i386) with an usb huawei E352 3G modem.
The device shows as /dev/cuaU0.0 and works fine with ppp connection.

[2.3.1-RELEASE][admin@pfSense.arda]/root: cu -l /dev/cuaU0.0 Connected ATI Manufacturer: huawei Model: E352 Revision: 11.102.23.04.314 IMEI: 355788042317587 +GCAP: +CGSM,+DS,+ES
But after a week, every week, the connection goes down and the only way to get the connection up again is to reboot or unplug and replug the modem.
If I unplug the modem /dev/cuaU0.0 becomes /dev/cuaU1.0 and I need to reconfigure the ppp connection. And after a reboot the device reverts to /dev/cuaU0.0 so I have to reconfigure the ppp connection again.When the connection fails I get from the logs:
Jun 29 14:32:34 ppp [opt1_link0] MODEM: chat script failed Jun 29 14:32:34 ppp [opt1_link0] CHAT: The modem responded with "ERROR" to the command "AT+CGDCONT=1,"IP","internet.wind"" at ModemCmd: label. Jun 29 14:32:34 ppp [opt1_link0] CHAT: +CGDCONT=1,"IP","internet.wind"
I tried without success

Is there a way to get the modem up for more than a week?
Thanks

I have the exact behavior on my machine. In my case the newer e3272 cannot successfully dial a PPP link. So we opted to use the older more stable E398. One thing I notice is that whenever we refresh the device say unplug and re-plug it, pfsense will asssign a new port number typically in the sequence of cua1.0 then cua2.0 and so on. I think pfsense should refresh and check its active port because it think the same exact device you re-plug is a new device that why it assigns a new port number.
Also you should disable gateway monitoring on your modem and select always up. USB modems are very delicate and sometimes a sudden drop in signal or sudden lagg on the USB bus will make pfsense remove the 3G/4G gateway from the gateway group.

I cannot disable the gateway monitoring, since the modem is a member of a failover gateway group. I'm using 8.8.4.4 to check this gateway.
Everything works fine for a week then I have to reboot to be able to use the modem again. -
I'm planning to setup a failover via a 3G stick.
The first step was to configure it and let the USB modem in test phase for a while.
I'm experiencing the exact same issue… Every 2 or 3 days (sometimes just 1), the connection is dropped and the /dev/cuaUx is changed... :-(
Is there a way to force the modem to be reachable always via the same device?/x
