Archer MR400 disconnecting, changing to MR500 also disconnecting
This thread has been locked for further replies. You can start a new thread to share your ideas or ask questions.
After having more than 3 years of troubleless use of Archer MR 400 we suddenly experienced the router disconnecting every 1-10 hours. This happened in mid January 2024.. We got a new SIM card - the same problem with disconnecting. We then bought a new router Archer MR 500, but have the same problem with disconnecting "all the time". The router is appr 120 km from our home so we need a stable connection for controlling heating etc at out cottage. Any suggestions?

Hi, since the MR400 was working fine before, suddenly the issue started recently and even new MR500 has the same issue, it might be ISP base station issue as well, please confirm with your ISP about it.
And for the current MR500 issue, you could also try the beta firmware provided here: Unstable LTE Connection with Archer MR500 and MR550
For more troubleshooting suggestions, please refer to this thread: LTE keeps disconnecting

@Sunshine I have tried everything suggested. It took about an hour before the router disconnected after installing the beta firmware. The simcard is new and working in other devices, nothing wrong on the mobil providers side, checked different bands, selected 4g only... same issue whatever I try - disconnects after 1-3 hours - or a day. It is not possible to log in to the router after it has diconnected, I need to reboot and then everything is fine (for a short time..)

Hi, may I know who the ISP is? and you mentioned that the SIM card is working fine on other devices, did you test for longer time to monitor the internet stability?
Besides, you mentioned that you are not able to login the router when it disconnects, are you able to ping the router LAN IP address when it happens?
After confirming the above details, I would to like to escalate your case to our senior engineer for debugging.

@Sunshine My ISP is Talkmore/Telenor Mobil. I haven't tried to ping the router when it disconnects, I've gone straight to reboot since there is no signal.. Thanks for your follow up, - my case has already been escalated (TKID240222099).

@Sunshine I eventually gave up tp-link :(. I bought and installed a new router from another producer, and the connection has worked perfect without any diconnections. I have no idea why, but something was really messed up with tp-link at our cabin...
