hi guys, want to ask a question here, sorry for my bad english btw

My fren's house install maxis ftth and also subscribing Astro iptv connect to the maxis thompson

Here are the situation.

Currently he subscribe another Astro iptv (2nd astro iptv) which is connected to the asus rt-n14u router. Once connected the asus wifi will totally cut off means no connection at all. If unplug the LAN cable from asus the wifi will be back to normal and internet connection is ok. Already tried everything but till now wifi didn't work. I show u guys the diagram.
