I'm trying to get connected on the WiFi (2.4Ghz) and get internet access through my LTE connection.
Right now I only get access from the wired port.

Is there a basic or default config I can load to accomplish this? Winbox has a different window for each individual component but nothing to configure it all in one place. Perhaps CLI would be easier?

Sounds like you need the correct SRC-NAT rule.

Post output of this command from console:

ros code

/export compact

Or maybe you are missing a bridge port membership?

Yes, could be. Depends on how device is confgured, therefore we need output of the above command. /

I'll run the export when I get into the lab this morning.
Thanks for the quick response!

You should configure your IP address on your bridge, and make both our ether ports and wlan port member of that bridge.
Also configure your DHCP server on the brdige.
If you do that, all devices connected to the bridge, either via wlan or cable, will get a valid IP and will be able to reach the internet.
Maybe you also shoud configure a NAT masquerade rule
