Connecting 2 Modems

[DarthJus]

Hi, I have got 2 modems (Airties and TP-Link) and huge house. 1 modem (airties) have iptv and stand in living room but we need to use internet on bedroom so if i try connect both of them dsl line either one cant get ip via dsl, then i tried one of them using access point. when i try mesh i do almost everything give them same ip block (192.168.2.xx) same channel, closing dhcp server from second modem, find each other from mesh and mac numbers but cant connect internet. then i connect them with ethernet cable now my problem is if i got connect second modem with ethernet cable i can connect both modemds and internet but when i tried it from second modem's wireless i can't connect anywhere except second modem and have limited connection. I can't write fluent in english and can't explain very well but i ask elsewhere and still can't find any solution. If anyone can help me or show some way i'll be grateful. Thanks a lot.

Only one modem can be connected to one DSL line at a time.

Make sure the ethernet cable between them is connected to a LAN port at each end, not a WAN port.

Make sure that, although the IPs are in the same block, they are not the same and the second one is not inside the first's DHCP range.
