im 500mbps fiber with rt86 but i cant get full speed of it. anyone can teach how to optimise?

How old the fiber modem?
If u r using Unifi ask them change the fiber modem for free problem solved.

And connect to wire or 5G WiFi only can use full speed.

try disabling QoS, enable NAT acceleration.

Also check BTU connection to router, make sure it is gigabit, some BTU model only providing 100Mbps.

Apologies for the late reply. Extremely busy with work.

Unfortunately everything was done in a rush, so didnt manage to capture photo.
In general, you'll just need to remove the heatsink (front, back) then cut the heatpad to size.

I also agak-agak only. But you may use previous measurement as a guideline.

To report back, below is the stats:
2.4G - 46 degC
5G - 50 degC
CPU - 59 degC
Ambient - 30 degC

FW: Merlin 384.19

Latest firmware is 3.0.0.4.386_41634-g08f88ae

Anyone updated it? no issue right?

You might want to flash the beta firmware for now
Version 9.0.0.4.386.41994 Beta Version
https://www.asus.com/my/Networking-IoT-Serv.../HelpDesk_BIOS/


https://kb.cert.org/vuls/id/434904

Is the beta version stable? I normally only flash official version

Not sure, I'm trying merlin firmware now.
You can save the router settings before flash the firmware, if not stable then flash back the old firmware and then restore it's settings.

since o one report issue, will flash it

Tried with the new set power adapter.. no response . Maybe will send to asus servie center to repair..

Is any user for this model confirm it work with ExpressVPN if I want to install into router?

Need Help! Anybody knows which version of latest firmware is the most STABLE for Aimesh on ac86u twin unit.? Asus original firmware or Merlin? Currently using 3.0.0.4.384_82072. From time to time still need to manual restart both routers.

look guys! what i found after 2 years of using this router as node in my living room inside the tv cabinet. To my horror after i dismantled it to check the heatsink.

Phenomena: usually this node in living hall is not so loaded but recently due to emco, my whole family is fully loaded this node since they all online study and WFH at the living hall. It started to slow, wifi signal strength dropped and disconnection. So since too much complaint from family members, i decided to swap the node (B) with main unit (A). So node as main units and main units became node for testing purpose. From here, i checked the log, its keep giving me core disabled time to time. Frustrated since im using original firmware not able to know the temperature reading and using my hand touch the router seem cool. i decided to load merlin firmware to check the temperature (>95c during idle) @.@. So the finding is as per attached picture. Mis-process from manufacturer. Luckily i got copper shim, thermal pad and thermal paste at home. I put copper shim sandwiches with thermal pad with Thermal grizzly Kryonaut between chip and copper shim.

Result: Idle temperature is 55c while loaded is 75c. Its stable under loaded at 73c~77c all time. 1st unit is from 1st batch Y2017 manufacturer date on the back label no issue and have thermal pad on cpu chip. This affected unit is Y2018 manufacturer date. Both using is on passive cooling now. I have added cooling fan but didnt use it. If i use the fan now, the temperature will down to 5xc during loaded. Still a very good router.

Hi guys

My AC86U still going strong. Want to add a mesh node for better coverage upstairs. (Router downstairs).

30mbps only. 😂 so which cheap ASUS router should I get as the node.

Get another AC86U? Malaysian set now cheap RM500+ only.

Ya wor I didn’t realize so cheap now.
AC68U and AC86U price diff less than 50 bucks
Then they promoting those AX 2x2 for around same price as AC86U haha.

I bought mine in 2019 for RM500 from overseas. Now can get a local one for same price. Not bad.

Didn’t even do anything just use stock firmware. Damn stable.

Guess Asus Malaysia slashed the price so much after AX86U release.
I got my AC86U for RM11xx back in Nov 2018. 3 years old. Now, half price d.

Yeah, great router. Stable & powerful.
