If using connection-mark then you still have to mark traffic in Mangle. The previous post suggested I unset the connection mark, it would be simplest if someone posted their working config including mangle rules etc. I think you need to look at the link below to understand what needs to be sent via...

@SiB, i did the testing last night: I dont have any other Cell showing up for B3. So I enabled B1, 3 and 20 - as these are three bands i have seen before. The I did cell lock on B3. I could immediately see the band 3 being the primary band and then there was no CA band. As such I disabled the Celllo...

Hi SiB, you have vast knowledge of Mikrotik and have been very helpful, many thanks for that. On the new SXT-LTE6, I dont have any bands selected and in cell monitor i can see the B20 and B3: B20@5Mhz and B3@15Mhz. Now you see the reason I want B3 as my main band. If I do CellLock to Band3, i dont g...

It seems the cable was faulty. I took the sxt down connected with a different cable and it worked straight without resetting it. So I laid a new cable and it's back in business. Thanks for your help Sid.

Thanks Sid, I changed the poe adaptor, but still no good. The cable length should not be problem as I have been using same cable for my earlier sxt - lte. I think either the unit is faulty or the cable is not connected properly. I'll get it down over the weekend to check.

I have another RouterOS box, tried ping, mac ping, telnet - doesnt work
Try mac telnet, it starts login and password and then tries to connect and within 1 second it shows disconnected.

I have setup the MacServer to All interface, RoMON is e...

I have recently replaced my SXT-LTE with a new SXT-LTE6, which is externally mounted and in a difficult to reach position. I had tested it couple of days on the latest long term RouterOS, before mounting it outside and everything was working fine with its default configuration. Then after mounting i...
