Spitz GL-X750C4 Verizon Modem Hangup and Surprise Success

dcp · March 19, 2020, 1:43pm

Having issues getting my GL-X750 to connect reasonably quickly to Verizons network. After every reboot the modem take several minutes to possible hours to connect. I only say “possible hours” because I have not timed it just yet. Looking at the systems logs I see the same message repeated over and over again “modem hangup”, then randomly I end up with a successful connection.

One thing that I immediately notice is the order of the log messages Connect: 3g-modem_1_1_2 and 3g-modem_1_1_2: renamed from ppp0… See below.

This will be a failure

Mon Mar 16 00:32:26 2020 daemon.notice pppd[6308]: Connect: 3g-modem_1_1_2 <--> /dev/ttyUSB3
Mon Mar 16 00:32:26 2020 kern.info kernel: [14491.639478] 3g-modem_1_1_2: renamed from ppp0
Mon Mar 16 00:32:27 2020 daemon.notice pppd[6308]: Modem hangup
Mon Mar 16 00:32:27 2020 daemon.notice pppd[6308]: Connection terminated.

This will be a success

Mon Mar 16 00:32:32 2020 kern.info kernel: [14497.535158] 3g-modem_1_1_2: renamed from ppp0
Mon Mar 16 00:32:32 2020 daemon.notice pppd[6537]: Connect: 3g-modem_1_1_2 <--> /dev/ttyUSB3
Mon Mar 16 00:32:33 2020 daemon.warn pppd[6537]: Could not determine remote IP address: defaulting to 10.64.64.64

Here are the logs that show a successful connection along with many prior failures of the same type “modem hangup”.

Anyone have a thought as to what the issue might be?

Thanks in advance!

When connected I have the following single and info. Signal looks fine, other then the 99 value, which I assume is OK since the Internet is working fine.

+QNWINFO: "FDD LTE","311480","LTE BAND 2",1150
+CSQ: 25,99

Found this thread on X750 band locking. I figured the modem might be taking a long time to scan through the various bands so I ran AT+QCFG="band",0,a,1 to lock the modem to band 2 and 4. No change.

I’m not 100% sure band 4 make sense, some sites suggest this is an LTE band, others suggest band 13 might be better. Lots of information about Verizon bands online but not sure which is best but I used a phonearena.com link. Would love to hear about a better source for this information. Overall the band lock did not seem to make a difference either way.

Has your SIM card been activated on another device?
For Verizon, the X750 supports only activated SIM cards

dcp · March 24, 2020, 12:15pm

@luochongjun yep, it was activated in another Verizon device. I also logged into the Verizon portal verified the new IMEI of the X750 was showing up instead of the old device. Also, I’m able to get online, it just takes 1+ hour to connect.

How about the speed then?

dcp · March 27, 2020, 1:06pm

Speed is ok, getting ~20/20Mbps with 60ms ping. Would be nice to get a better download but I’d be happy with quick connections right now.
