Ermm, i don't think so. Flashing CFE can be easy but people are not kind to share their AC18 Cfe with working AiMesh. This has been done after 30+ hours of testing and unbricking process.  

This tutorial only for 380.70 usage only. Do not follow from stock firmware.

pincode (can be any 8 digit numbers) [eg: use your birthdate, 19830516]

Also, this cfe has been modified by me to 1000Mhz and strongest possible WiFi signal (28.50 dBm)! Have Fun!
It is advised to set the wifi channel fixed after updating,

thanks for the hard work, will feedback after i try. by the way, how is your experience with the latest firmware so far?

I only used it as AP haha, no problem for me

will find time to test the ai mesh and report back 

You have 2 AC18? I tested it and it is working, Im using ethernet backbone. The setting need to be tweak a bit to suit different people needs.

yes, one main router (hgg firmware), the other as media bridge (koolshare).

btw this CFE mod can only work with koolshare 384 firmware?

the firmware I give is koolshare 384 one ya.
I'm not sure will it work for other but supposed it will. Most of the bricked router is because of CFE problems.

What are the improvements observed from 384.18 with AiMesh from old 380.70_HGG-FINAL?  Mind to share some figures?

What are the improvements observed from 384.18 with AiMesh from old 380.70_HGG-FINAL?  Mind to share some figures?  Also, is it mandatory to have 2 or more AiMesh routers in order to benefit from AiMesh feature?

what I can say is 380 is more stable

Hi bro, thanks for sharing the files and tutorial. I would like to feedback that your method works splendidly, no bricking encountered. I am happy to report that the AiMesh function works. Your oc of 1000 core / 666 ram is not stable for my unit running in router mode (crashes every few minutes), so I have reverted to 800 core / 666 ram as default.

Can we upgrade from 380 to 384 using the existing router GUI? I mean just upload the *.bin file?

Hi Sifus, I'm using 380.70_HGG-FINAL, but I can't get max speed during speedtest using all interfaces.  Wifi 2.4 (max: 140mbps), wifi 5Ghz (max: 150 mbps), LAN gigabit interface (170Mbps).  But my unifi subscription is 300DL/50UL.  I used to manage to get 300 Mbps with my old d-link DIR-842 router via wifi 5Ghz and LAN gigabit interface. 

Can anyone show me how to achieve max limit, what configurations to look out for in this router and ASUS firmware.

You should get full speed on 5ghz and LAN connections, try to make a factory reset. I can get those numbers last time when I'm on 380.70 HGG. Now also can get above 400mbps for -50 signal quality.

I only used it as AP haha, no problem for me :D

hi prokiller,
try to open extracted cfe bin but seem cfeedit.exe failed to read it. any advice?
