The drivers seem to be marked to build as module by default. If built this way as in installable ipk they fail due to failing dependencies. Best built-in.
Hi VintageRain,
kindly, could you build 19.07.3 with that patch for the Wi-fi module, please?
Because 19.07.4 contains issues and router restarting if clients a lot, like 12..15+ even without the patch.
Thank you.
The supplied psu is weak when compared with another PSU that comes with an ac1200 capable router. Just a thought that while the basic psu is fine with a single association several may drain it. Look for something with 2A.
You might try my build, it contains a fix about a issue on mtk_soc_eth. I had packet dropouts and Wifi restarted while streaming from Netflix or Disney. The router is 25 days stable as we speak with great reliability.
the problem not with your build, the problem with 19.07.4 version. The problem happening when the router have 12...15+ wifi clients then router is restarting. This firmware is contains the issue http://downloads.openwrt.org/releases/19.07.4/targets/ramips/mt76x8/openwrt-19.07.4-ramips-mt76x8-tplink_c50-v4-squashfs-sysupgrade.bin but previously version 19.07.3 doesn't.
I've checked it on 4 routers and it's working fine
That's why if it possible to build 19.07.3 version with your patch 
. kindly, could you do it, please?
I've flashed 19.07.3 - 4 routers and it's okay, but the signal for 2.4GHz is poor because of this firmware without your patch.
I have one router with 19.07.4 and it's still restarting (flashed by http://downloads.openwrt.org/releases/19.07.4/targets/ramips/mt76x8/openwrt-19.07.4-ramips-mt76x8-tplink_c50-v4-squashfs-sysupgrade.bin)
OpenWrt version's 19.07.5 is out since a few days, EDIT: The issue is not fixed in the new release.
I can confirm mtk_soc_eth.c 's bug is fixed ( * Fix regression in 19.07.4 causing transmit timeout and packet loss on mt7620 devices)
@darkmaxx1 You mind building 19.07.5 with drautmann patch for the rest of us, when you haver a chance?

I've flashed 19.07.5 and the router is not restarting when clients more than 12 , but the signal for 2.4Ghz is still poor. 
Hello! I've rebuilded v19.07.5 with the dtrautmann patch above here. You can try it out for yourself!
Wow, okay, I will check it now.
Thank you.
Flashed but I got this issue when I'm trying to install packages.
The installed version of package kernel is not compatible, require 4.14.209-1-d92769dc… while 4.14.209-1-369232b7… is installed.
Kindly, could you keep the same kernel version when you rebuild it?

Ah, this is a problem when you self-compiled your images (as described here: https://openwrt.org/faq/cannot_satisfy_dependencies). I'll guess it's either the firmware is built with your needed packages, or some other ways...
he built with this patch and packages are installing fine, but the problem with this version 19.07.4
How-to-compile | but don't need to exclude luci, i think 
Config: https://downloads.openwrt.org/releases/19.07.5/targets/ramips/mt76x8/config.buildinfo
Alright, I've recompiled OpenWRT per the instructions, and it appears to be OK. 
I've reuploaded the firmware to https://github.com/tk-nguyen/openwrt/releases/tag/v19.07.5. Thank you!
EDIT: It appears the 5Ghz Wi-Fi does not work. Will have to investigate...
EDIT 2: Looks like I fixed the problem by not touching any compilation flags 
Okay, I'll check it tomorrow and let you know.
Thanks.
Hello,
kindly, could you check parameters for 5Ghz because it's not working and no associated?
Your last build:
-2.4Ghz is looks good
-but 5Ghz is not working
-Packages from repo are installing properly
1-st it's okay build
2-nd it's your last build
Just only now I saw your update
EDIT: It appears the 5Ghz Wi-Fi does not work. Will have to investigate...
Thank you.
I've recompiled the firmware and uploaded to https://github.com/tk-nguyen/openwrt/releases/tag/v19.07.5 again. Let me know if there's any problem.

Now it's looking good.
Am going to check how it will work with clients.
Thanks.
You asked so I uploaded my bin
Here my current build:
https://1drv.ms/u/s!ApO7cZgI36BfjhANKFes9agxZBEk?e=dHx7zY
OpenWrt 19.07.5 / luci / luci-ssl / drautmann's 442 patch.
I saw tk-nguyen's compiled his bin also, I won't post another build as it is a bit useless if everyone upload and share his own build.
