Any update? Still the same issue.

With 1 external antenna (RI=1) CA drops, but when using 2 external antennas(RI=2), sometimes it drops only after days, I had a period when it was not dropped for weeks.

And CA died...
CA was B28 only, then B20 only and now CA is not connecting at all. Will not restart anything, but assume that rrc=4 is not a workaround, problem is somewhere else.

I gave a try on rcc=4 once more, hard restart, power off. While it works for half a day, its CA combination is weak. Primary B7, CA only B28, have not seen other bands. Total speed is still respectable ~150Mbps. Will leave as is and monitor behaviour. Primary Band B7@20Mhz earfcn: 2850 phy-cellid: 4...

rrc=4 does not work for me. The strange is that some month ago CA was always connected for weeks, then I got ATL for a test, which also drops CA, now I am connected back to Chateau LTE18 (LMT) with 2 external antennas and now CA drops. Only change I have made is RouterOS upgrade from 7.8 to 7.9rc3, ...

Interesting that this is not an issue for mobile phone (Iphone 13 pro in my case). So I assume it is modem related.

Now there is a dilemma with new ASL. I live 1.5km from LTE-A tower. Now I own indoor Mikrotik LTE18 router with EG18-EA modem (support 2x2 MIMO) + 10m cable + single Iskra P-42 antenna(9.5dbi @ 1800/2600Mhz). RSSI around -60db, SINR around 18-22db. Now the options to FULLY utilise the network and sq...

Are you using the internal antenna or external? Does the same issue happen on 7.6rc2 on testing branch? External antenna, connected to Main socket, detected correctly by the device. Scrolled through 7.6rc3 changes and which of those might improve this behaviour? 7.6rc3 not tested, always upgrading ...

Hi! I have an issue with CA assignation LTE router with modem EG18-EA (LTE18 indoor modem distributed by LMT operator in Latvia) Start of random test. Modem is up like for a day.
