How to Set Router? Can Not find Network Setup Info

[MikeTranch]

I looked at the JK Help Forum, found an _empty thread about how to to set router.

I'm trying to get rid of the "hairpin error" but other threads mention running network test.

Where is that? I can't find it in the app.

Also some links in the app go to non-existent webpage.

Thanks for anyone who can point me in right direction.
