Hi, All,

For anyone suffering from a random disconnect issue on Archer MR600, here are some details for you:

Firstly, please try to figure out whether it is the LTE or Wi-Fi connection that dropped out.

Some tips might help:

1. check whether the 4G and internet lights turn off or not.

2. if there is a wired desktop, please monitor the Ethernet connection for a while.

 

For unstable LTE connection, here are some suggestions:

Case one: The disconnection is caused by the Auto switch of 4G bands.

[Troubleshooting] LTE keeps disconnecting

When you check the status under web UI>advanced before and after the disconnection, you might see different 4G bands. For example band 3 when the internet is working, then change to band 20 which caused the drop-out.

 

 

Solution: Please refer to this link to install the beta to fix the bands.

[Solution] Manual Band Selection for 4G WiFi Routers

 

Case two: the unstable SIM carrier.

If you put the SIM card into the smartphone, you will experience the dropout as well.

Solution: Please contact the SIM carrier and change another SIM card for the test.

 

Unfortunately, if the LTE connection still kept dropping out, please send an email to support.forum@tp-link.com with the following information:

1. Who is your SIM card carrier?

2. Some screenshots about advanced>status page before and after the internet dropped out.

3. the system log after the internet is disconnected for 5-10mins.

 

Note: Since this post is long enough and not convenient for users to locate the solution, I will lock the post now.

It is encouraged to send us feedback via email so that we could find out more potential reasons which caused the disconnection, and update this post with more suggestions regularly.

If you have any further issues, please leave me a private message or start a new thread and tell me whether these suggestions worked for you.

 

Thank you very much.
