MR200 and MR600 keep dropping LTE connection !
This thread has been locked for further replies. You can start a new thread to share your ideas or ask questions.
I've tried two models: Archer MR200and now MR600. Both router constantly drop LTE connection. Another router, DLINK DWR921, on the same sim card, never drops LTE connection. My other devices on different sim cards don't drop connection in this area too.
Signal strength is 75% all the time (also durong connection drop it shows 75%). After connection drop the router has sometimes trouble reconnecting by itself. The drops happen multiple times a day, sometimes even as often as less than hour between.
i've tried (on both routers, now I only have the MR600):
- updating firmware
- manually creating ISP profile (the ISP is T-mobile Poland)
- moving the router around household
- rebooting multiple times
- power off/on cycles multiple times
- cleaning sim card
- antennas repositioning
Nothing helps. i'm gonna return the MR600 (alresdy returned MR200). And that's a pity because otherwise they are great devices, much better than tye D-LINK that I have...
Any ideas?

From the picture attached, it shows internet is unavailable, please ensure that the MR600 works fine, and you can get internet from it.
Please tell me the current beta firmware version numbers.
Good day.

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 brief introduction of the disconnection issue and the troubleshooting method you have done and the corresponding results.
Note: Like the LED status, whether the sim card works well in cellphone directly, whether the router still has valid IP address and gateway.
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.
Thanks for your support and cooperation in advance. Good day.
