-.-?
If I am not mistaken, few days ago, you said you don't have internet connectivity and now no hypptv?

How do you setup the IPTV in first place? 

EDIT:
If you select the unifi preset, the hypptv LAN port changed to Port 1. Previously it was Port 4.

When you setting up your ppoe connection from fresh, you will be prompt to select your connection type. When you choose ppoe, you will be given a list of pre-define profile which includes "Unifi - Malaysia". When you select the profile, your router's LAN 1 will be automatically reserved for iptv. If you chose custom profile, then you can define the vlan id and tick the 802.11 tag and you can proceed to the next phase of your router setup. Beta firmware user here. So far i never face a single problem with hypptv. the only thing is, my ethernet lan cable for hypptv breaks out. need to replace it soon.
