New AirPort Extreme - devices don't communicate

[gtmac]

I replaced my 5th Gen AirPort Extreme with the newest version.

With the new AE I can't access my wireless printer, I can't use RDP from my phone to local PC, and the remote app on my phone doesn't connect to iTunes.

On the old AE everything works perfectly, I reconnected it to test it out.

What might I be missing in the set up?

Is the new Extreme set to Bridge Mode or DHCP & NAT mode?

DHCP. All devices receive an ip and can connect to the Internet. They just can't talk to each other.

I am wondering if there is something between the AC wireless in the iPhone 6? But that shouldn't effect the PC to printer.

Is the 5 GHz network and 2.4 GHz network running on separate network names (SSID)? Are some connected to the guest network by accident?

No guest network. Now I think it's an IPv4 and IPv6 issue.

Try doing a factory reset.
