The above command will tell the modem to use only 5g an 4g bandwidth and will prevent the modem from dropping to 3G/WCDMA mode. However, I have personally seen my router completely lock up and not have ANY internet connection after many hours of use. I can only think that this might have something to do with carrier aggregation and the tower needing to send a handshake or something to the modem and is unable to because the 3g bandwidth is turned off. I’m probably wrong on this but usually a quick reboot solves the issue but then the router will need the above command sent to it again or it will default back to ALL bands becoming used again.
I have an unlimited business plan and its a regular phone SIM not a Home Internet plan. SIM is not restricted in any way. It connects to 5G SA Bands absolutely fine but after a few hours, it will drop down to a 5G NSA Band for some reason. It never re configures itself or switches back to 5G SA Band unless I reboot the modem. I am a little ways from the closest tower. My phone only shows 1 bar and sometimes drops to SOS mode dropping all cellular signal. The GL-X3000 shows 3 bars when connected to 5G SA Band and only 2 bars when it drops to 5G NSA band. I would think that the router should check for a stronger signal from time to time and reconfigure itself but apparently it does not do this and requires a reboot of the router to connect back to 5G SA Bands.
I have enabled 5G SA only and will give it a try but it usually will simply lock up without any internet connection until I reboot. I’ll post back with results. Here are my setting via AT command so you can confirm that 5G SA only has been enabled.

Came home from work and the router was completely turned off. Had to unplug and plug the router back in for it to turn on and reenable cellular connection.
Again, I always get booted off of 5G SA and forced onto 5G NSA bands after several hours. If I disable 5G NSA bands I loose all connectivity and apparently the router shuts itself off. A reboot puts me back on 5G SA bands.
Is the time fixed when there is a problem?
Can you share your device with goodcloud? I will view this phenomenon remotely Technical Support via GoodCloud.tar (192 KB)
I can not tell if the time is fixed when there is a problem. It seems to happen at a random time as opposed to X hours. It’s something I will keep track of if I can. I disabled DNS / Cloudflare settings on the router and wondering if that is causing issues with my ISP when trying to renegotiate connection? Testing again today with DNS set to Automatic.
Edit: Router died again around 6 hours in. Drops all cellular and WiFi services. Rebooting and leaving all channels and bands enabled. Will check status again in 6 hours.
i did this (Except the 5G SA Band, i kept it open, doesn’t matter i try to hold 4g and not 5g ) and it holds 4g now for more then 2 days whit the latest firmware 4.0408release3
so the masking mode (open) seems to work!
