Why are they bad at it if they are also using WiFi as the backbone?
Surely the backbone signal is the strongest?

I started having issues in master when some of wifi (either 5GHz or 2GHz) interfaces would not come up and it now takes several router reboots to get them all going. I have compared the output of wifi status in both cases and noticed that when the interfaces did not come up, the output was missing "ifname". Does anyone else experience something like this?
All it takes is to restart wifi and very often not all interfaces come up. There are some messages related to one of the interfaces.
daemon.notice hostapd: nl80211: Failed to remove interface wifi2 from bridge br-lan: No such device
user.notice root: ip link set dev wifi2 up
daemon.notice hostapd: wifi2: CTRL-EVENT-TERMINATING
daemon.err hostapd: hostapd_free_hapd_data: Interface wifi2 wasn't started
No issues at all here, besides irqs being on cpu0, usually building master every few days (dumb APs with WDS)
I see them on both:

Could it be related to the addition of ubus reload? I had a similar issue to you on master when using the 5ghz wifi in client mode and frequently doing wifi reload. In my case a single reboot always fixed it. In the flyspray report, ifup lan always fixes it, so it's not an exact match, but the report mentions that netifd "gives up prematurely" which seems relevant.
Could be; I will keep an eye on that bug. I have for now switched to 19.07 and a non-ct firmware and things seem to be working way better.
R7800 19.07.0 with ath10k-ct-htt and 802.11r AP mode working nicely. The main router a wrt1900acs 18.06.5 with 802.11r working nicely too. The AP failed a couple of times and i prepared to upgrade the firmware as @huaracheguarache pointed out but i'll wait to see if it crashes again. Still 48h without problems.
Thanks for the tips!
Does anyone wants to help me with the k 5.4 ? Pretty stuck with the eth problem...
Where are your k5.4 commits?
And what exactly is the current problem? wired does not work at all?
Will push the commits this night to a repo.
Current problem: wired looks like it works (with ifconfig i can see that packets are actually transmitted) but for some reason they don't get received (or the device can't send data to the router). Problem is that no error is reported and I can't really diagnosticate the cause of this.
Tried with both the dsa driver upstream and the normal driver.
I haven't tried wireless network as i think there is something to fix with pcie (and it looks cause some system lock) so I'm trying a very base build.
I'll take a look if you think its far enough along to try on ipq8064; however, adding another device at this point could be unhelpful.
In any event it will take me at least a few weeks to get going.
Thankyou for working on this.
Well you will have a base to work on... will post here the repo
You could try the newly released beta firmware (I think the correct images are the ones with "full" in the name): http://candelatech.com/downloads/ath10k-9984-10-4b/ath10k-fw-beta/
The release notes mention a crash fix: Jan 16, 2020: Fix crash that is probably related to AP rekey problem.
I did try the HTT variant of that beta firmware and the issue was still present. The original ath10k would crash at least once a minute (master). I reverted to 19.07 with the latest ath10k firmware/board files from kvalo and it is unbelievably stable after a few days. Everyone here stopped complaining about wifi. I am gonna run this for now.

@hnyman @anon98444528 here the repo https://github.com/Ansuel/openwrt/commits/kernel-5.4
Some kernel flag still needs to be included...
(also funny thing... i accidentally deleted the patch5.4 in the commit stage so i actually had to rework the patchset AGAIN....)

Any thoughts on starting a new thread?
I'm happy to start one but I'd think it be better if it is not device specific (say "ipq806x: kernel 5.4") and a respectable community member (like you or hnyman) is the op.
I suspect the frequent communication like what was done for 4.19 (which I like) would not be appreciated in this thread.

wanted to open with a ready to test pr but since i'm having little time and this problem... will open an help thread ahahah
I'm still complaining about wifi with ct firmware 
I do try it once in a while when I'm pinged in the github issues to try new builds. So far I have not found a ct version that works well for me. It also seems there are similar reports to mine in the github issues:
https://github.com/greearb/ath10k-ct/issues
Developing wifi firmware is not easy. Unfortunately there seems to be only 1 developer behind ct (greearb -- I appreciate your efforts, thank you!) but it is very tough when you don't have a variety of hardware to test various interop scenarios.
FWIW, this "old" version works best for me and it still seems to work with hnyman's more recent builds.
