Is the 386.3 alpha coming up soon.... :eek:
Or maybe the man is busy working on a new, yet to be announced router?

You should follow @RMerlinDev on Twitter ;-)

Works great on AC68U.
Thank you very much for your work.

Support for that model was completed a while ago, however Asus had to delay the launch of that model, so it's going to stay dormant for now until they get closer to its launch.

1. Fixed CVE-2021-3450, CVE2021-3449 OpenSSL related vulnerability.
2. Fixed authentication bypass vulnerability. Special thank Chris Bellows, Darren Kemp – Atredis Partners contribution.
3. Fixed PPTP and OpenVPN server username/password GUI bug.
4. Fixed high CPU utilization issue.

Hi,
I noticed that both my RT-AC86U AiMesh Nodes 2.4GHz Band(s) are stuck on Channel "1", they do not follow the Band setting on RT-AX88U AiMesh Router, be it set to "Auto" or any Fixed Band except Channel "1".
(See AiMesh Configuration in my Signature)
Wonder if this is specific to my configuration or a generic issue (bug), so would be grateful if someone with similar AiMesh Configuration can help confirm. Thank you.
Edit: Sorry, I posted on wrong thread ... do not know how to move it to the thread on ASUS RT-AC86U Firmware version 3.0.0.4.386.42643

Tested the new official release for Asus RT-AC86U vs. the current Merlin release and no improvement over the CPU overheating - they are identical twins. Both increase CPU overheating by 5°C.

No change should have been expected. The issue is a physical problem with the router, that has been exacerbated by the new features in the latest firmware.

Your only options are (from easiest to hardest):
a) Ensure your router is clean and free of debris
b) Make sure it has good airflow
c) make sure it is not sitting on top of any sources of heat
d) Turn on EEE (energy efficient Ethernet) from the command line, and add it as a startup command
e) Use fewer LAN ports
f) Install a cooling fan on the back of the router
g) Open the router and modify the heatsink to make proper physical contact with the CPU
h) Contact Asus and RMA the router

And yet another completely successful dirty upgrade on my favorite-of-all time router, formerly and officially known as "the-router-that-may-not-be-discussed in this forum" For those of you who get it, this is a very solid firmware track, as have been the others.

Done everything to this POS ASUS RT-AC86U.

The RMA is not an option.

ASUS wants money up front and the postage and wait time are classic stumbling blocks to wait the customer out until the warranty is up or the router fries. And opening it up they categorically state voids the warranty.

Out of interest, what is your current temperature both with and without the fan in action?

Having a temperature rise of 5 degrees is entirely expected with this firmware. What matters is how high it got to.

If your temperature without a fan doesn't get above 85-90 degrees C then you really don't have too much to worry about.

If you have a fan on, then you shouldn't get anywhere near that.

Hi Guys,

Just wondering if this is the right page to ask about the built-in cake-qos. If not, please let me know. My question, what would be the default overhead settings for a fiber connection, modem bridged to my RT-AX86U?

I've been using the conservative default option but I don't know if I'm using the correct one.

Thanks in advance!

e) Use fewer LAN ports
While this has been shown to be effective, I consider it ridiculous that one of the main ports the equipment was designed to use causes the machine to run on the warm side.
The best mod for cool operation is a fan - if airflow can be directed to enhance natural convection currents, pushing heat up through the exit ports at the top from below, so much the better

Wow, less than two days ago I half-jokingly posted about (perhaps) soon seeing an Alpha release of 386.3, but also figured "nah, not likely, since Asus hasn't released any new firmware in quite some time (either GPL sources or compiled releases). Much has changed in those 36(-ish?) hours since then: it seems that Asus has been busy dropping new releases that seem to resolve many more "newly discovered" vulnerabilities for various models. Bring on the next round of Alpha testing....
