Hi, @Cathy
i have GL.inet X3000.
why this command return nothing (only OK)?
gl_modem -B 0001:01:00.0 SAT sp AT+QENG=\"neighbourcell\"
i want to search available tower (5G SA) using command line in .sh script.
gl_modem -B 0001:01:00.0 SAT sp AT+QENG=\"servingcell\" response:
+QENG: "servingcell","NOCONN","NR5G-SA","TDD",405,857,0CE580002,71,2A,634080,78,12,-87,-3,-7,1,-
OK
Got it.. gl_modem -B 0001:01:00.0 SAT sp 'AT+QSCAN=3,1'
this command only return 4G towers. but if i use only 5G SA n78 then this command nothing return.
but now got it.
gl_modem -B 0001:01:00.0 SAT sp 'AT+QSCAN=3,1' # Scan LTE + NR5G
gl_modem -B 0001:01:00.0 SAT sp 'AT+QSCAN=2,1' # Scan only NR5G (5G SA)
I am following your posts on making Jio work. Very helpful!
I have changed the IMEI and then locked the band to n78. I'm getting high speeds, but every two seconds the network drops down.
Then I saw your post on locking the tower, but when I run the command gl_modem -B 0001:01:00.0 SAT sp 'AT+QSCAN=3,1', I get an Error.
Any ideas to help troubleshoot?
why speed drop? and what do you actually want?
No idea why it is frequently disconnecting. I have also upgraded the module to the version you have mentioned, but still the connection keeps dropping every few seconds. It's very frustrating. I want to keep the connection stable.
what is your gl-inet and module firmware version?
check module firmware version by AT+QGMR
gl-inet is X3000 and module firmware version is RM520NGLAAR01A08M4G_01.205.01.205
Other settings are below:

becouse of sms issue i use old firmware. sms not working after release 0409release3.
i use jio sim.. my internet is stable no any issue.
Thank you. I downgraded my firmware to this version and restarted the modem, but the problem seems to persist. I also locked the band to n78. (see screenshot)
I had also shared my logs with the support team, they mentioned that I have poor signal. But from the dashboard, that doesn’t seem the case (see below).
Have you started using this device recently, or have you been using it for a long time and the problem just started a few days ago?
in my area some cell tower get too much slow speed (30mbps) and some cell tower fast speed (250mbps). so i locked on fast cell id.
you should try different cell tower..
I still started using this device recently. However, my speeds are good (over 200 mbps). The only problem is that internet keeps dropping. In terms of signal strength, I already see good numbers.
Here are the list of towers I see:
* Track Protocol must select IPv4 only.
This seems to have helped. Stable connection for the past few minutes 
This is a firmware issue. If you select both ipv4 and ipv6 then the internet remains unstable.
So for stable internet select only ipv4.
otherwise, this device provides very stable internet.
now, is your internet stable?
It worked very well for one day and then again became intermittent.
Now the latency has become very high and the speeds have dropped to 1 Mbps. Pages do not upload easily.
