Hey TP-LINK !!

I want to use IPTV in bridge mode but when i turned it ON so my internet speed goes from 50 Mbps to 1 Mbps and upload speed failed to test on Ookla Speed Test on both WiFi and LAN on Main Deco and after i turned it OFF so my speed back to 50 Mbps again but i want to use IPTV in bridge mode to use my ISP IPTV services. I had Deco X20 and there was no issue on IPTV Bridge Mode but Deco X20 had some features compatability issues with Deco M4.

WAN Port fixing settings is useless. I think you have to remove this settings. It can take long time to get ip address after i set manually WAN port 1 so it's better to remove it from Deco App and Deco firmware.
