Hi,
After i used AT command to lock the bands, the commands works as long as i dont reboot.
After rebooting, the modem reverts to original setting.
Anyway to make it retain the setting?
Please try lock the bands in the GUI and see if it saved.
Hi,
Do you mean the band masking function?
Yes, you can either exclude certain bands, or you can include certain bands, depending on your need. If you want to lock to a certain band, you would use band masking to block access to all others.
Hi, yes, the settings in under band masking are retained.
However, sometimes after reboot.. occasionally, my 4G locks on to B40 instead of B28(my service provider) although i maintain the same profile. And i lose connection.
So i am wondering if there is a way to force B28 on the Modem via AT command.
Hi Bruce,
I tried using Bandmasking option, Block or Open, i tried Both.
My operator has 2 different service.
One is LTE which uses B5,B38,B40.
The other service is 5G-NSA using B28, N78.
These 2 service are not interchangeable .
I am using the 5G-NSA service. Ive tried band masking option . Either block or open.
Ive set my router to reboot daily on schedule.
However after reboot, my router will sometimes still lock on to B40, causing me to lose internet.
You can try this method to test:
Check the current modem online information, to get the freq_band and pcid,
gl_modem -B AT+QENG="servingcell"
If on the LTE, lock command:
gl_modem -B AT AT+QNWLOCK="common/lte",1,<freq_band>,<pcid>
Make sure that the router will not be transferred, just use on a fixed position, otherwise it will cause unable to access the Internet.
After this method to lock, don’t lock on the WebUI, otherwise it will be covered when it in dialing.
