i am f*cked up: my first mikrotik device, out of the box, put SIM inside, it connects to the Mobile Network, shows me external IP on LTE interface. Perfect signal (NodeB is 150m away).
BUT i dont get any data threw it.
it shows me tx data but no rx data.
traceroute etc,. just stops at the mikrotik router.
Finally after a firmware update to router os 7.8 its working now.
until a reboot, after reboot the webinterface is not available anymore and winbox does not find the router
I had the same problem also with Telekom DE. No RX Data, just TX. Well, the problem (in my case) was the APN. My Chateau 5G R17 ax has not automatically added the APN of Telekom.de, so I had to configure it manually. Then everything worked flawlessly.
