I'm new to MiroTik and trying to set up a new SXT LTE6.
I was unable to update due to the error "could not resolve the DNS name" and I'm unable to ping 8.8.8.8 or anything else. It seems like there is just not a connection. I've tried a couple of sim cards and those are recognized but I get the same error with both.
I'm using the default configuration although I've tried turning off the firewall and that didn't help.

I'm at a loss what to even troubleshoot because I can't get any connection. Any suggestions would be appreciated.

Hello,

Have you tried using the Quick Set feature?

Is the APN correct?
Have you enabled Firewall Router?
Have you enabled DHCP Server?
Have you enabled NAT?
