I just tried a vanilla master image, and a personal build from master, but the 2,4 GHz radio is not showing up. Has anyone seen something similar lately?
Thanks.
Finally I found the time to do some tests on the build with kernel 5.4.
wifi: same speeds of r12255 build, no noticeable differences in 2,4G and 5G, in both laptop and phone
lan: in my laptop, using the kernel 5.4 build, the speed is less than half than the previous build:

Even with a factory reset and new flash without keeping settings, I have settings not sticking so I can't perform stability tests and log catching.
Hope to see a stabler 5.4 kernel build soon

Have you turned on RPS as recommended?
System --> Startup --> Local startup:
echo e > /sys/class/net/eth0/queues/rx-0/rps_cpus
Save and reboot.
I am on 5.4.42 now, and with the above setting, I can easily get 800Mbps NAT speed (soft offload ON), and the LAN is 930-940Mbps (same as it always was).
I had this issue when I first upgraded from 4.14 to 5.4. Putting the factory image back via recover resolved this issue.

Me too 
Couple of last test builds had WiFi not starting unfortunately.
Also, I am moving to a TP-Link MR600 since it has an integrated LTE modem. Can still provide builds but they won't be hardware tested as they used to be. To add to that, as you have noticed I am not that active anymore due to free time being sparse. Having said that, in a month, I have a two months vacation and if there is time after trying to hack the MR600, I will give the DIR860L/MIR3G some love

Figured out why the wifi didn't work on the master branch. The wifi PHY names got changed and thus hostapd could not bring them up. You could probably do this easier but a factory reset and setting up the interfaces from scratch did the trick. Currently testing r13533 which has some interesting commits included (packet steering and ethernet driver improvements).
Some preliminary WiFi throughput numbers:
5 GHz:

2.4 GHz (heavily congested appartment building, peaking at 72,6 Mbits/s):

Since I have a 25 Mbit/s symmetrical connection I am not able to really test packet steering under real life conditions.

Could you provide the output of the following command on the current build?
cat /proc/mtd
@Axl_Mas has problems with the settings sticking and I think it has to do with which flash memory addresses are mounted.
So settings might not stick and you have to do a factory reset in order to make WiFi work. For the brave people wanting to test, remember you do so at your own peril

Im still using r12255.

Thanks for the info, that helps a lot since I don't have the device anymore.
You are probably going to flash the newer build, could you also run the same command on it please? 
Sure, no roblem. I do own a second DIR-860L and I will flash r13533 in a couple of minutes and provide the output of the command. brb

Thanks for the information.
If you compare both outputs, mtd6 and mtd7 have different sizes, both larger in the newer build.
Do you settings stick after a reboot? In case they don't create a conf files backup so if sh*t hits the fan, you can always upload those
My changed settings were still valid after a reboot but sadly I can't use this build in my enviroment.
First of all I can't get along with DSA (imho not very userfriendly if you need vlans) and second there is no more ebtables included in your latest build. I've just installed 19.07.3 to see if this build will fit my needs. Kernel Version seems to be a bit newer than r12255 but the first problem that I've encountered with this official OpenWRT build is that DFS channels are not working, only channel 36 seems to be working, otherwise I do get "Wireless is not associated" the following syslog entry:
daemon.notice netifd: radio0 (7271): WARNING (wireless_add_process): executable path /usr/sbin/wpad does not match process 6949 path ()
daemon.notice netifd: radio0 (7271): Device setup failed: HOSTAPD_START_FAILED
If I can't fix this error I will return to your r12255 build as I never had any issues with it.
The change to a DSA is a big one. Unfortunately I don't use vlan so can't offer you advise there.
Forgot to include ebtables. It will be present in the next (test-)build.
Have you set your country in WiFi settings?

Thanks, I've tried with driver default and with my country. I'll stick to your r12255 build as Wifi doen't seem to be stable on 19.07.3 (several clients got disconnected a couple of times). The change to DSA really bothers me as swconfig always worked fine and afaik DSA can't even be proper configured via Luci.
Strange since the WiFi never has been more stable for me with the devices I connect to it. So YMMV I guess.
DSA is the chosen path so when 19.07 doesn't get anymore updates that's it for swconfig. Reading this topic it looks like you are able to use vlans but you have to jump through a few hoops which are on fire 
Keep in mind that I was talking about the Wifi with 19.07.3. I haven't tested the wifi much with your latest build as this build is pretty much not useable for my envirioment. I do need ebtables and working vlans for my IOT and guest network. I'll test DFS and Wifi throughput with your latest build later on and report back but to be honest I never had problems with the wifi on r12255, it was always stable and the throughput was also fine.
The "ethernet driver improvements" sound quite interesting but I don't even know if that would do anything for my DIR860L as I'm using it only as a smart switch + AP behind my main Router (WRT3200ACM).
Anyway if i figure out how DSA works (thanks for the link) I'll give the next (test)build a try in my productive enviroment. The good thing is that I have a second backup device so I can quickly change back to r12255 if something goes wrong.

But in my case there is no way to keep settings after reboot on r13533.
I tried to flash factory build from D-Link recovery, to normally flash the update without to save settings, reset after install, double flashing but the settings are not saved in any way.
Also after set manually the new settings and saving them as backup, after a reboot I can't restore it.
@Bartvz , if you have any idea or tests to perform please let me know
I've just flashed r13533 again on my backup device to do some speedtests and I can confirm now that any saved settings will be gone after a reboot. So it seems to a generell problem with r13533.
I guess we have to wait for the next build...

Great work on the optimized builds and many thanks!
Your r12255 has been rock solid for me (using the router only as an AP, currently with 20+ days uptime) in terms of Wi-Fi speed and stability, whilst the last official openwrt build was quite buggy - frequent wi-fi issues, especially on the 5ghz band, requiring frequent reboots.
