Troubleshooting LTE keeps disconnecting
This Article Applies to:
All 4G LTE Routers
Issue Description/Phenomenon:
Some customers might experience interruptions or disconnections with their 4G LTE routers, their phones or laptops can connect to the router wireless network fine, while they display a 'No internet' error, and customers cannot access the internet. This article aims to provide suggestions on the issue.
Troubleshooting Suggestions:
1. When it loses the internet access, please check if you can still login to the router web GUI, then show us the Internet Status, SIM Card Status as follows. Compare the Network Type and Band, if they are the same as those when the internet is working fine:
2. If the band was changing to a different one when the internet interrupts, please follow the guide below to manually select a band that works in your network
How to select 4G band manually on the web interface of LTE Gateway Routers
If your LTE router doesn't support manual band selection, you could get the beta firmware from this thread:

3. If the problem still exists, please insert the same SIM into another LTE device or even a smartphone, then monitor for some time to confirm if the internet works fine and is stable.
4. If the 4G signal in your area is strong and stable, please try to change the Network Type on Advanced->Network->Internet page from 4G Preferred to 4G Only to see if it would be more stable.

@TP-Link I'm having the same problems, My Archer 600 v3 router keeps disconnecting from my Vodafone LTE. I did all the stuff suggested here but it still doesn't work. Flashed the beta bios, checked the APN settings, set the apn to dynamic, etc etc. Strange enough the problem occurs les ofthen when I connect to the 5G version of my network. I'm sure my LTE disconnects because under internet in the tetherapp the connection picto changes from green to gray.
getting very annoyed by this all..
please help

I have the same problem. It sometimes (every couple of hours) it disconnects and reconnects. I have Hardware Version V3 and the latest firmware update. I can't remember that I had the same problem with the firmware before. I tried everything what is possible even the new Cell Lock. No way to get rid of the problem. And it always switches between LTE and Lte Plus according to log entries.

Hi,
For the reported phenomenon, please confirm the following information for analysis.
1. Please log in to the router's web UI > Advanced > System Tools > Firmware Upgrade page and send us a screenshot of the Device Info section.
2. Where are you based, and who is your SIM card carrier?
3. How do you restore the internet after the LTE disconnect, such as rebooting the router, or does the router restore the connection itself after a while?
4. Please send us the screenshots of the Advanced > Status page and the Advanced > Network > Internet page when the internet works fine, and also when the internet stops.
Best Regards
