Thank you very much
Hello,
This new 19.07.4 STABLE release will keep the SNAPSHOT image configuration? I need to update in remote and can not lose any config.
Regards.
I'm not sure.

OK, I will wait to stay locally to update.
Regards.
Already tried using this image however after a few hours of testing and using my router, my wireless AP gets disconnected randomly. Upon further checking, I saw some of these logs:

Hello MacTavish,
"19.07.4 STABLE release" : just out of the box (eg cleared config), the wifi still sucks. 800Kbit/s. Distance 1 meter between antennas....
Is "/snapshots/targets/ramips/mt76x8/openwrt-ramips-mt76x8-xiaomi_mi-router-4c-squashfs-sysupgrade.bin" equal to your 19.07.4 ?
Note:
with the previous build, setting force Wifi N/legacy did not change anything
Not N/Legacy. Only N and tick "Force 40MHz mode" in Advanced Settings.
Sad 
I tried this one but it seems luci is not installed. uhttpd is not working either.
I will try. Thank you.
just FYI
Now (i think) it is official image, the opkg update software returns some upgradable packages. Some of them seem ready long before this image. Strange or I missinterpret the names

Hi mr.Mac i used your openwrt ver. for xi 4c router but some of them the wifi power is 14 dbm and the other is 20 dbm how can i convert 14 into 20 is it possible
i installed your openwrt in 120 devices and will be more
thank u
Some variants of 4C has 20 dBm option while others has 14. I'm guessing it's limited on eeprom. I don't know why it's limited like that but I'm guessing it involves where it's produced.

The country code (wifi adv settings) you select imposes the local restrictions on the wifi, power, channels and probably other 'max' settings.
I unchecked "allow legacy 802.11 rates"
I unchecked "Force 40MMhz mode" in adv settings
This immediately effect the TX/RX with my test machine
If I remember well, the slowdown occurs after 'some time' of usage.
but it is slow anyway (distance 1 meter)
Download 4.2Mbps (from internet) should be 40 to 54Mbps
Upload 10.0Mbps
I have just gotten a Mi Router 4C model: R4CM
It does not specify a firmware version but this is what is says on http://router.miwifi.com/cgi-bin/luci/diagnosis;
Version: MiWiFi Rom 3.0.16 Stable
I can't find my way to a URL with the stock value in the URL.
http://192.168.31.1/ redirect to http://192.168.31.1/cgi-bin/luci/web but no where a stock value to be found in the URL
Does anyone have a suggestion I could try?
PS. I can no longer login. it rejects my earlier set password. go figure. it's forcing me to isntall an app I don't trust 
EDIT: Can login now with password = admin and have gotten a stock value now.
Shall I just plow through or is this version a no go?
