Basically you mean your Smart TV can connect to the router via wired connection but can't work over wireless, thought it worked on wireless before. Correct?
I guess you are technical enough to understand DHCP stuff. Are you sure your TV is using DHCP not static IP?
Also after switching to a new ATT modem/router, did the SSID changed? If the same SSID is used, did you try removing the SSID and reconnect? FYI - the previous SSID setting on TV won't work as its MAC address was changed.
If the private subnet 10.0.0.0/24 is configured on the new ATT modem/router and it is not your preferred IP scheme, it can be changed. Just go to the modem/router's web console, change its internal LAN IP subnet to 192.168.1.0/24 (by setting the router itself 192.168.1.1/255.255.255.0).
So all IP addresses are now on 192.168.1.0/255.255.255.0 subnet? Any special considerations for giving the router an IP at 192.168.1.64?
If so, why it seems the old 10.0.0.x IPs are still bothering you now?
mmm.... are you inputing on a mobile? That's a bit difficult to understand your wording. :)

It seems you are using static IP now? Including the TV?

Did you do the above things? You haven't directly answered those questions.
Sorry I can't be available for a while. I opt out and let other experts help you.
Hi. My name is***** you for your question and the opportunity to assist. If your router is set to AP mode it will
not be handing out IP addresses. An AP only passes traffic through to your main router. If the ATT router is
handing out 10.x.x.x addresses then that is what your TV should be getting as long as it is set to automatically \get
an IP address.
When you tried the DNS address of 220.127.116.11,
was that set on the TV or on the ATT router?
Can you set that on the router?
Can you also temporarily hook the TV up to the router via ethernet and go into the system menu
and check if there are any software updates available for the TV.
