So TM sent me the new unifi plus black box and messaged me to install myself. I just unplug all cable from old unifi white box and connect to new unifi black box. Should be easy right? But it gives me this message "Your ethernet cannot reach internet." What is the problem? If I connect back to the old white box, no issue. Do I need configure/change anything in my router ka? Or this new black box can only connect using Wifi?

Plug in Lan port 1-3, leave port 4 disconnected.

I also got this new box but I am not bothered to install it. Happily still using white one.

If you want to use the same port as the old one, you need to remove the VLAN 600 tagging in router settings. New box is using Internet, no more special IPTV port. Alternatively, follow jusbella's advice above.

It looks to me that the white box is the WiFi router and that black box is just Android TV box. Two different things  You just need a LAN cable from white box to black box and to get access to Unifi TV channels. This post has been edited by Zot: Oct 15 2025, 01:51 PM

Update later. If use port 3 will not compete with my internet download? Last time I remember old unifi got this problem, if heavy download will make the TV lag.

So far for years I used a router with good QoS and download does not affect Netflix, YouTube, Unifi TV or other streaming. When I do download or speedtest while streaming video, the download or speedtest speed will drop and give way to the streaming when it loads the next chunk of content. If not using router with good QoS then I guess the video quality will drop or playback will lag when downloading, unless TM have some QoS somewhere.

But now trouble news, do I need to set QOS for port 3?

Best you do so........however hereby lies the issue, if you enable QOS, you will break NAT Acceleration....... So you must pick.....you want bandwidth or latency? Note: Above doesn't apply for native IPv6.

By the way, are you sure it does not apply to IPv6? From what I know, only the name is "NAT Acceleration" but it is actually more like routing acceleration. For some routers, it is known as Cut Through Forwarding, Fastpath, Packet Runner, Flow Acceleration or Flow Cache and only affects traditional QoS.

Can confirm it doesn't apply to native IPv6, IPv6 NAT on the other hand is another story. I mean what is the point for anyone to use IPv6 NAT instead of native IPv6? If you asked me, there are two types of "acceleration". One is truly hardware accelerated and the other is more like software "hack"
