Model: Archer MR400  
Hardware Version: V3
Firmware Version: 1.9.0 0.9.1 v0001.0

I have a tp-link 4G LTE router used in Thailand with AIS's SIM card inserted. There are intermittent 4G connectivity in these days. 

I download the system log and post it in the following.

This issue happened randomly, sometime more than 5 times a day or 1~2 times for most cases

Does anyone has the issue like this? How to fix this 4G connectivity issue?

Thanks~

@JeffreyChen 

 

Thanks for the information provided. We can do some troubleshooting first. 

1. What is the led status of Archer MR400 when it lost 4G connectivity? Try to log into the web UI and take some screenshots, including the status page, network map, and advanced-network-internet page at the same time. 

 

2. With the SIM card inserted to the cellphone directly, does it have the same issue? 

 

3. Have you ever tried to change another SIM card? And you can create the network profile manually to give it a go.

@Kevin_Z 
This router was deployed in Thailand so neither I nor my customer don't have chance to see it, because it was setuped on a very high rack.

For the SIM card replacement and LED status, it needs customer's agreement.

 

Does this router has the compatibility document?

Does these intermittent 4G connectivity happened rarely in your experience?

 

Thanks!

@JeffreyChen I have exactly the same problem in Cochabamba - Bolivia, With the same SIM card I tried on the MR200 and it works very well, but on the MR400 it has the same error:
