Router used with 4G sim card disconnects from internet after running for a few hours. Restart needed to get internet working again. Full 4G signal where used. Any ideas what to do to fix this issue?

To those who may be concerned,
Hi all, if you have the disconnection issue with your LTE gateway, please help us to provide the information attached below. So that we can speed up the whole process and locate your issue quickly and try to figure it out.
1. The model number of your LTE gateway router. And its hardware and firmware version.
Note: Please ensure the firmware is up to date.
2. Please give us a brief introduction of the disconnection issue and the troubleshooting method you have done and the corresponding results.
Note: Like the LED status, whether both wifi/wired connection do not work or just one of them, how often it stops working, whether the sim card works well in cellphone directly, whether the router still has a valid IP address and gateway when it stops working.
3. You can test whether the sim card works well with your cellphone, or you can change another SIM card to check the stability; create the network profile manually/change wifi settings are worth giving it a go as well.

4. When your router stops working, you can take some screenshots, including the Basic-network map page, the advanced-status page, the advanced-network-internet page. They will help us to do further analysis.
Thanks for your support and cooperation in advance. Good day.

What is the light status of the Archer MR400 when it lost connection?
At that time, please login to the web interface of MR400 and send us a screenshot of the advanced-status page.
Meanwhile, please go to advanced-system tools-system log page, click save and export the txt file to us.
Below are some suggestions you can give it a go as well:
1. Ensure that the firmware is up to date.
2. Create the connection profile manually with APN information.
3. Customize the wireless settings, like wireless channel and channel width.
May it help and have a nice day.

Thanks for your reply. We have developed a debug tool to locate the issue. Please follow the steps below to get the debug log and System Log for further analysis:
1. Below is the download link of the debug firmware.
http://support.tp-link.com/f/88e1be2c74/?dl=1
2. Once the router has the new firmware, please run the 'TP-LINK LTE Log Tool.exe', select the mode as 'net monitor' and start it.
3. Just keep the router and the Tool run until the internet drops on your router, save the debug log into a new folder. The log directory will be opened when the tool is stopped. And, please go to Advanced-System Tools-System Log page, save the system log and save it in the above new folder. Please note that we need both the debug log and the system log.
4. Please run the Tool again, select the mode as ' dial once' and start it. Check and tell us the internet status once the tool stops. Then save the debug log and system log into another folder. Please note that we need both the debug log and the system log.
5. Please send us the above two folders which contain two debug logs and two system logs.
Thanks in advance, and have a nice day.

Hi,
Same problem here. Sometimes I can access the admin web (192.168.1.1) and issue a reboot, otherwise power off/on to restart the Internet connection.
Firmware Version: 1.12.0 0.9.1 v0001.0 Build 190730 RC.59984n
Hardware Version: Archer MR400 v3 00000001
Let me know if you need more trace/debug data.
After adding an automatic reboot at night 03.00, the connection loss is less frequent.

Same problem as others here, too.
Rebooting does not always help even!
I have tried with UK Three and Vodafone SIMs.
Works fine on mobiles, etc.
What is the actual solution to this problem?
I am past Amazon return policy sadly.
Thank you!

I have the exact same problem. It is extremely frustrating. Every 1-2 hour the router loses signal and I have to reboot. Sometimes I can reboot via webpanel, sometimes I have to power the device off and back on again.
This started 2 weeks ago, before that the unit was working 100%. I have not updated the firmware or done any changes that could provoke this fault.
Updated firmware yesterday after reading this thread, still no improvement. I will install the tool that was linked to in this thread and e-mail support with the findings.

Same problem here. Archer MR400 v1 with Firmware Version:1.6.0 0.9.1 v0001.0 Build 181112 Rel.65058n. Tried with two different sim and provider but the result does not change. Randomly he loses his connection and accessing the admin it says "unknown error". A reboot is required to reestablish the connection.
