Check your LAN cable with a tester. Make sure all 1 - 8 lights are all flashes continuously.
1 - stripe orange
2 - orange
3 - stripe green
4 - blue
5 - stripe blue
6 - green
7 - stripe brown
8 - brown

1,2,3,6 are data transfer wires, while 4,5,7,8 are DC power.
If either one of 4,5,7,8 have problem, your network connections will became 100mbps only.
If either one of 1,2,3,6 have problem, you will can't get any connections. You need to repair the connector with crimping tool.

Just buy the full set of repair kit from shopee

For your second problems, about the port 4 issue. My recommendation is to change your router IPTV settings to Unifi-Business. No matter that you are home user or business user because Unifi-Business can free out all the 4 ports. If you don't have Unifi-TV set-top-box, just switch to Unifi-Business.

Most probably is the LAN cable has problem, need to replace or repair. Inside your LAN cable has 8 wires, there have 8 pins on your LAN cable head connectors. Either one of the pin 4,5,7,8 was oxidized or not contact well. That's why you need to replace a piece of new CAT6 LAN cable or just buy a set of crimping tool, that comes with LAN cable tester. You need to repair the crystal head with new one.

Better just buy the shield types

Sometimes it does not relate to the router, I have one of the CAT6 cables that connect from my gigabit switch to my PC and always drop to 100mbps too. I just straight take out a LAN cable crimping tool to cut out both side head then replace new one.

Just follow the 568b standard, self DIY not difficult to learn too.

I got one question to ask about the Asus router. Did anyone here notice that when we set our 5GHz wifi to channel 36, 40, 44 or 48. The speedtest result on wifi can reach to maximum speed but if we set the channel to 149, 153, 157, 161 or 165, the speedtest result on wifi only have 95% out of maximum speed. Especially when I set the channel to 165, I only can get 150mbps on speedtest. Why?

Now I was just locked my 5GHz to channel 36 in order to enjoy the maximum internet speed.

Last time I really don't know the 5GHz wifi speed is related to channels. I just left them "auto". No wonder why sometimes my router can't get full speed on speedtest. Now I better just lock it to channel 36.

Signal is stronger but wifi speed is getting slower. I would prefer to wifi speed > signal strength because I have 1 unit RT-AX86U with 2 units of RT-AC86U as aimesh. So don't worry about the signal problem.

not-recommend to enable it, just stay with channels 36-48

You can get high speed easily but need to sacrifice wifi signal strength.

Maybe just need to replace the power adapter

Hi ASUSmy, I want to ask about a question about unifi TV vlan500/600 tagging issue.

I have 1 unit RT-AX86U as main router and 2 units RT-AC86U as aimesh node with 2 units TP-link easy smart switches.
My unifi is located at upstairs with ethernet networking. I was successfully tagged the vlan500 and vlan600 through my 1st easy smart switch down to my living room 2nd easy smart switch.
My 1st RT-AC86U is located in my living room which is connected to my 2nd easy smart switch.

I tag my first easy smart switch, vlan500 port 1 untagged then port 2-15 tagged then port 16 not member. Then vlan600 to port 16 untagged then port 2 tagged, the rest are not member.
The PVID settings is Port 2 PVID 1, Port 16 PVID 600, the rest are PVID 500.
Port 1 is connected from my main router. Port 2 is linking down to downstairs in my living room.
My 2nd easy smart switch is vlan500 port 1 tagged, port 2-7 untagged, port 8 not member, then vlan600 port 1 tagged, port 8 untagged, the rest not member.
The PVID settings is Port 1 PVID 1, Port 8 600, the rest are 500.

So my 1st RT-AC86U connected to the port 2 of my 2nd easy smart switch and no issue to connect to wifi. I can get connected to the internet without problem.
UnifiTV is connected to the port 8 of my 2nd easy smart switch and able to stream the live channels without problem.

However, come to my 2nd RT-AC86U which is located in the basement floor (downstairs again from living room). No matter how do I configure the vlan and pvid, I still can't make my 2nd RT-AC86U get connected to the ethernet. My 2nd RT-AC86U is linked to the port 6 of my 1st easy smart switch. I was tried to link another ethernet LAN cable from my main router LAN2 to my 1st easy smart switch for example port 14. Then try to change the default vlan1 port 6 and port 14 to not member, then create another new vlan2 to set port 6 and port 14 as untagged. Then set port 6 and 14 to PVID 2 but I still can get my 2nd RT-AC86U get connected to aimesh.

Any solution to make my 2nd RT-AC86U to get connected to the aimesh?
I am deciding to buy another new easy smart switch to link my 2nd RT-AC86U if really can't solve this problem.
