Our home network configuration:
#1 Apple Express Time Capsule #2 UVERSE Router #3 Apple Express Time Capsule
Both Apple Express Routers above are connected wired and are in BRIDGE mode with the UVERSE doing DHCP. All three routers above can/do create separate (SSID) WIFI networks. Anything connecting to ANY router above be it iPhone, iPad, MacBook Laptops, Windows Laptops and AppleTVs have solid internet and interconnectivity with each other. SMB works, VNC works, AirPlay works, and Time Machine Backup works.
The above everything WORKING was with the UVERSE NVG589 router.
We had to have ATT replace the UVERSE router and now have the PACE 5268AC.
I can report that everything IP based WORKS as above BUT we NO LONGER have AIRPLAY and TIME MACHINE BACKUPS working as they did.
I did some tests this weekend and found that AirPlay to an AppleTV only WORKS for connections to a single router. I mean that if the AppleTV is connected to Router #1 above, ONLY LOGINS to Router #1 can AirPlay. LOGINS to router #2 or #3 do CAN NOT AirPlay.
When I moved the AppleTV to Router #2, LOGINS to Router #2 can AirPlay, but LOGINS to Router #1 or Router #3 can NOT AirPlay.
Bet you can guess what happened when I moved the AppleTV to Router #3.
It made NO difference if the AppleTV connected WIFI or WIRED.
IM not the expert here, but it appears that ATT has BROKEN our ability to connect Apple Devices in an expected way. This appears that AirPlay and TM backup is now broken for many if not ALL. I see no settings in the UVERSE router that can FIX this issue. My bet is that somehow they have broken the BONJOUR protocol that Apple uses for AirPlay and TIME MACHINE.
PLEASE PLEASE ATT or ANYONE FIX THIS ERROR.
