Here take 
Thanks again, seems my throughput issue is caused by smth different
probably your adapter is not compatible or just your drivers out of date, have you checked them? both my adapters work fine with the new FW, my xiaomi mi5 works @ full 433 and my asus rog gl553vw with intel AC 7265 works @ 650-866, havent tried something else , but this specific build is as good as the factory in AC 5Ghz, but i still waiting for answer from developer if he has fixed the 2.4Ghz issue!!!
Probably, or maybe smth in eeprom, Iām on different device with the same chipset
Strange, with VPN (OpenVPN) wrt1x00ac series is very more fast and stable that mine dir-860l b1
Hi labrok
thanks for pointing out that a more recent snapshot helps on the lagging 860L wifi.
(I have not tried the custom build of this thread so far)
I've applied 2017-08-26 snapshot and made some tests.
So far I ran "WiFiPerf Endpoint" on an ipad air 2 (iperf3 listener on it which is said to have 2 MIMO antennas) and ran the following against it from my PC: .\iperf3 -c 192.168.1.182 -t 600 -P 4
Wifi 5 GHz - performance now pretty stable at 400-433MBits/sec when right next to the 860L.
(LEDE reports it as connected with 585MBit VHT-MCS 7 with -58 dBm)
But thats a very sensitive transfer rate, minimum solid obstacles in between quickly take it down to 200-300MBit.
Before that I rarely reached a max of ~120MBit and often only 40-60 Mbit/sec and sometimes stalls or timeouts. So I am quite happy now (crossing fingers). Unfortunately I did not document my tests before the snapshot patch.
Wifi 5 GHz - performance is further noticably more stable at constant ~100MBits/sec when standing at the far end of my living room with the ipad.
(I think my TV has AC WiFi has well, but I don't see an app on it, to run iperf. I just had lags on network DLNA playbacks before. Might take some days to keep an eye on that, if it still happens. Often it would start fine and after ~20 minutes with 17.01.2 it would become unwatchable due to permanent buffering. But I did not try to monitor RAM or resources on LEDE in parallel)
Since you noted issues with 2.4 Wifi, i did another test:
With 2 parallel threads of iperf3, i get 105-110MBits flat out
PC --LAN--> 860L --2.4G--> same ipad air 2
when standing next to the 860L (LEDE reports it as connected with 144.4Mbit MCS 15 with -38dBm.
I ran it for 10min and there were no dropouts, the transfer rate was stable.
(2.4 Wifi was on channel 11. I think 5 Ghz had channel 52 during the tests)
config wifi-device 'radio0'
option type 'mac80211'
option hwmode '11a'
option path 'pci0000:00/0000:00:00.0/0000:01:00.0'
option country 'DE'
option htmode 'VHT80'
option channel 'auto'
config wifi-iface 'default_radio0'
option device 'radio0'
option network 'lan'
option mode 'ap'
option encryption 'psk2+ccmp'
Going to try 2.4Ghz, but the issue for me is when i connect a cpe210 (long range AP) as client dir-860l it works fine for about 1-3 minutes andf then tx-rate falls to 1 and disconnecting, then dir860l needs reboot from button to work again!
i forgot: same effect on channel 36, has less throughput: 200-240 Mbit/s. but I think 36 is used pretty commonly on stock routers.
i tried a scan on Luci for other networks in the area, but that takes forever, no result so far.

Have you tried ruling out that the long range ap is the issue? Sometimes wireless chip sets don't play nice with each other. Other then that, do you see references to the long range ap in the system log?
Try installing a wifi scanner app on your phone to see which bands are crowded and which ones are not. Also AC is way more sensitive to stuff like router placement (preferably as central and as high as possible), type of material used in your hose (it really doesn't like concrete), etc, etc.
@All, new build up for your testing pleasures. It has been humming along quite nicely for the last two days on my router.
with stock firmware 2.4Ghz is stable, tried with cpe210 and tl-wa7210N both woirking perfect, but when we go to lede ,it start bugging, anyway, 5Ghz band works fine atm, just a new bug is that we cannot use usb Storage, kernel is not compatible with the packages.
Which build of LEDE are you testing? Is there anything in the logs?
It can be the case that certain packages cannot be installed because the buildbot is building LEDE packages for a newer kernel version. You can try force installing packages though.
New build is building atm mostly for this commit: https://github.com/lede-project/source/commit/6aa46bf05e056444490b4978c53bf6fb183fb0e3
OP updated with a new build, enjoy!
whats new in this build? last one had some minor issues with the 5Ghz (bandwidth was less than previous one) and couldnt install packages from lede repository (incombatible kernel) has it fixed in the latest? thank you in advance for you good work!
As listed in the OP, mostly upstream changes. But there were updates to the ethernet and the wifi driver.
Since I have a slow DSL connectiond and I am not a heavy wifi user, I haven't noticed any issues with 5GHz.
Why you sometimes can't install packages form the LEDE repo is because the kernel version changes upstream and the packages in the repo have the upstream kernel version hardcoded. You could try force installing them but please keep in mind that that might bork your router.

Many thanks Bartvz for your great builds!
I've found this commit https://github.com/lede-project/source/commit/67ac017fefe8552b4e864d0494e892efe4fb9710 related to the fix of these critical vulnerabilities on Dnsmasq https://security.googleblog.com/2017/10/behind-masq-yet-more-dns-and-dhcp.html
When do you have time, could you please be so kind and release a build with this fix included? 
Done! Check the OP 
Hi Bartvz,
Would be nice to get the SFE back. As I am not using SQM, but I have a gigabit fiber connection, I can utilize and test this feature. Maybe you can add and disable SFE by default, but at least if someone want to give it a try it would be there.
Hi! Bartvz, you always write here (OP), what is your (OP) if you simply have all the firmware that can be downloaded from useless ... then what is your (OP) ???????? It does not work with installing the file list, it does not recognize the usb external hdd, let alone disconnect it, wake up the router, and even list the many problems with the OP firmware shared here. If I boot up with the Padavan firmware then it is interesting to work all its functions. I do not see much of this in my mind that there is a weekly firmware shared between everyone (OP) and one of them. So I do not understand why they do not share what works well on this part so it does not make much sense to download stuff for the router 2-3 hours and not good. Hello all
The latest version of this firmware is running really great!
My internet is supposed to be 100/10, but nominally I get 118/12. With sqm, I'm getting very solid 110/11 with an A bufferbloat score!
I think turning off sfe has really allowed the router to keep up!
