MikroTIk itself released a different wireless package for IPQ40xx which can be downloaded from here:https://download.mikrotik.com/routeros/7.1beta3/all_packages-arm-7.1beta3.zip
i.e. within the ZIP file there´s a wifiwave2-7.1beta3-arm.npk which can easily unpacked. The folders also contain new firmware bin files. I´m curious whether they use any opensource parts...

I use the source from "git clone -b hAP-ac2-cleanup https://github.com/robimarko/openwrt.git" to compile a build.
However, the 5GHz download speed only around 16XMbit. Is it normal ? Any method to improve the speed ?
I saw some post said using ath10k-ct-smallbuffers driver. I don't know how to use .
Please help.
Thanks all

That does not look correct, I remember getting much higher speeds.
Smallbuffers driver is already included due to 128M of RAM.

thank for reply.
Is the smallbuffers driver default to use ?
Thanks
Yes, its the only one packaged
Hi,
I would like to try OpenWrt on my hAP AC2.
Where can I download the latest firmware build or do I need to compile my own?
If so, can someone provide a link to a tutorial or a guide on how to compile the firmware as I am new to this.
Thanks
My current build of firmware for hAP AC2
Download https://disk.admlr.lipetsk.ru/s/s2JJKcndnRA2nbc
This is my how to build firmware for hAP AC2
- Download ISO nemesis-xfce-20.10.11-k5.4.50-x86_64.iso (Arch Linux version of Porteus)
http://www.mediafire.com/file/z7aa9e5fjv7mar6/nemesis-xfce-20.10.11-k5.4.50-x86_64.iso/file
Logins and passwords (look at this screenshot):
- Install Nemesis on your flash drive or HDD >>> https://pastebin.com/czT9QPx2
NOTE. File system that you will be clone openwrt must to be POSIX filesystem (like as ext2, ext4...) and to have a good supply of free space.
By default all changes will be saved on /mnt/sdb1 (look at option changes=/dev/sdb1 in /boot/syslinux/porteus.cfg)
3.Warning!* /mnt/sdb1 must to be POSIX filesystem (like as ext2, ext4...) - Boot up from your USB Flash drive or HDD
Nemesis via second menu - Xfce (changes) - Open terminal and run these commands:
su
toor
export FORCE_UNSAFE_CONFIGURE=1
env FORCE_UNSAFE_CONFIGURE=1
setup-pman
# where is /mnt/sdb1 is POSIX filesystem (like as ext2, ext4...)
cd /mnt/sdb1/

Technically you can use any Linux distro to compile OpenWrt as long as you have the required build dependencies.
I compiled this build on Ubuntu 20.10 without problems but I forgot to backup the compiled binaries before distrohopping to Arch Linux 
can you show your 5GHz wifi download speed ?
Thanks
I only have 75mbps internet but one day I've transferred a file from my phone to my laptop at 220mbps
First image is default settings and router mod.
Second image is ap mod, firewall and dnsmask disable.
I use @Blaze last build on cap ac. Internet speed is 300/15 Mb, maximum speed on my phone is 200/200 I tested.
Sorry guys,
I am not a developer, so would be really appreciated, if somebody creates the guideline:
- What and how should be backed up to have the ability to roll back to Router oS (what prerequisites should be?), - license file and that's all? what about making a full dump of existing Router firmware to be able fully recover the routes from this snapshot?
- What build (or initial image to download)? - better to keep the link to the top of the page with the latest STABLE one.
- What should be installed on Windows PC in order to load the image to hap ac2?
- What should be done - after testing image in RAM, and decided to write to flash?
I have been trying to build a firmware package for the past few days, but unfortunately have not managed to get it right.
I downloaded the linux iso, copied to usb flash drive, ran the installer, but cannot boot from it.
Tried with Rufus usb tool and was able to boot from the linux iso, but received error message about saving, creating a dat file.
Tried the commands in the terminal, saw some messages about pacman and keys...nothing else happened.
I only have a Windows 10 PC, I am not familiar with linux and such commands, is there by any chance an all inclusive step-by-step / how-to / beginners guide?
I also checked the OpenWrt wiki guide using VirtualBox and the Debian iso from osboxes.org, but it did not work.
On a positive note, I did manage to install your firmware build on my router and it is working well so far. I use the default config + SQM and Adblock. I noticed that the LAN IP cannot be changed from 192.168.1.1.
WiFi connection range and speed is better than stock firmware.
Will keep researching and try again when I get a chance, hopefully can get official support soon...
- Any errors after ran the installer did you see?
- Do you use BIOS or UEFI with Secure Boot?
Open your BIOS and disable Secure Boot, then is use Legacy mode (not UEFI).
Run gparted and format partition to ext2 FS for example.
Use this FS for save changes in /boot/syslinux/porteus.cfg (for example changes=/dev/sdb1).
If you use non POSIX FS, you are must to create dat file for save changes in /boot/syslinux/porteus.cfg (for example changes=/path-to-your-dat-file.dat). - I am able to change LAN IP https://i.imgur.com/ot31bHP.png
- ''Tried the commands in the terminal, saw some messages about pacman and keys...nothing else happened.''
Did you have access to the Internet at this time (what errors do you have)?
Thanks.
New build
Thanks @robimarko and john-tho on GH, hopefully this will get on upstream soon.
Happy holidays 
@geminis3
If you're on latest Windows 10, Ubuntu 20.04 on WSL2 works fine for compiling OpenWrt after following this guide and installing the required dependencies 
PD: I dual-boot Arch Linux 
along with Windows 10
Hi Geminis3
I find the file "ipq-wifi-mikrotik_hap-ac2_1_arm_cortex-a7_neon-vfpv4.ipk" in your share drive. Whether I need to install it ?
Thanks

No, on the main folder you have two .bin files
-
kernel.bin it's a temporary firmware that should be booted over PXE in order to be able to flash OpenWrt on your router using the sysupgrade file.
-
sysupgrade.bin this file can also be used to upgrade any previous OpenWrt version.
Edit: attached the official install guide
Edit 2:
The packages folder contains the packages compiled against this very specific OpenWrt snapshot.
When a new snapshot gets released the previous ones are unable to install new packages due to dependency errors, so this is useful if you delete certain package and need to reinstall it otherwise just ignore them.
So for getting 470Mbit/s @5.0GHz you basically installed the irqbalance and enabled it by adding /usr/sbin/irqbalance to /etc/rc.local, correct?
@all What is your maximum wireless throughput you achieve with your different builds on either 2.4GHz or 5.0GHz in your hAP ac2 or cAP ac? (Which patches so you use?)
I have failed to build a new snapshot of fw for hAP ac^2
