Hello!
I was using 6x RBSXTLTE3-7 routers for some years at a remote location to provide internet. I had some problems-disconnections with them and I thought it would be a great idea to upgrade them with 6x RBSXTR&R11e-LTE6. So a week ago I did.
From that day till today I have major problems with them. Mostly I have disconnections about every one hour which leaves the clients without service for some minutes and this is a big problem for me. Yesterday I used the at command to lock to specific earfcn and phy-cellid. Since then, the bandwith is great and things are better overall. I get about one disconnection per day but now when the modem disconnects it never goes back. I don't believe it is a cell tower problem because they never disconnect all together. It is completely random which router will disconnect. Any ideas?
* RouterOS = 6.47.9
* Firmware = R11e-LTE6_V027
