Chateau C12 LTE modem issues after last ROSv7.1beta1

Thu Jul 30, 2020 7:42 pm

I am not sure whether it is ISP issue or latest RouterOS v7.1beta1 upgrade.

I have got a decent signal I guess

Internet sometimes doesn't work at all. Sometimes it is fast.

Usual crap latency.

Yesterday, I noticed also some connection issues on my phone but Internet still somehow worked while Chateau C12 was dead or 2s ping with heavy packet loss despite LTE modem is more sensitive than smart phone.

I have reset to default configuration just in case I have some misconfiguration...sadly, no changes

I have already contacted ISP support about connectivity they sell to me...they promise 5G speeds but it is tragedy. Of course, they won't acknowledge it is their fault due lack of capacity on cell towers. It may be also just a coincidence of poor ISP connectivity and ROS upgrade. Hard to pin point. Only, time can tell.

I have upgraded LTE modem firmware and experimented with cell lock. There is slight improvements.

It may be also related to switched of "fasttrackt" for FORWARD chain. I cannot connect to SSH anymore.
