hAP ac as router only?

I’m currently running a full Meraki stack at home but I’m rather upset at the lack of IPv6 support on the WAN interface on my router. So I am planning on going back to my hAP ac and using it as just a router so I can get IPv6 support on my network. Am I correct in thinking that I would just follow https://wiki.mikrotik.com/wiki/Manual:Initial_Configuration and set Wireless Mode to disabled (or whatever that option is)? Additionally, I haven’t ever setup VLANs on a MikroTik device so I’m guessing I’d just follow the directions at https://wiki.mikrotik.com/wiki/Manual:Interface/VLAN

Yes, of course, you can turn off WiFI interfaces and use it only for ethernet routing.

And my assumptions for how to do what I want are correct, right? I know I will have to find my old posts here about IPv6 PD but that is ok.

Ensure on latest firmware first.
Not knowledgeable on ipv6 but assuming any setup will mirror an ipv4 setup for the most part??

Went to plug in my hAP ac to work on configuring it today and ran into an issue. Can’t find my power adapter for it. What size plug is it so I can find the correct one on Amazon?

“direct-input power jack (5.5 mm outside and 2 mm inside, female, pin positive plug) accepts 11-57 V DC.”

After you read the wiki ensure you visit the thread above.
Most Excellent thread on VLANs (will probably soon be a sticky once its fully flushed out)!
