Logging in to MR18 running LEDE OpenWrt

I have been using Meraki MR18 with LEDE as an access point. I originally set it up and need to log into it and review and make some changes for the SSIDs. How do I identify its IP address and log into it to make the changes?

Thanks,

depends how you set it up, but going by the MAC would be good start.

Thanks frollic.

So from the MAC address I can only see the router listed under the PPv6 address. It does not appear under the IPv4 address which I would normally type in the browser to get the logon screen for the MR18.

Any thoughts?

Thanks.

Any ideas please.
