I have installed openwrt, on TP Link Archer C6 V3, my 2.4 GHz network is not working properly, although I get singnal on the phone, after a while, the singnal is disappearing. And 5 GHZ signal is very strong. I am using openwrt latest version. How to solve it?
Let's start with your configuration:
Please copy the output of the following commands and post it here using the "Preformatted text </> " button:

The above commands are to be run from your router after you ssh into it (if you're using Windows, most people use PuTTY; on Mac or Linux, just use a terminal). You'll ssh using user root, password is either blank by default or whatever you set.

run each command (each line) individually, then copy and paste it into this forum -- be sure to click the </> code block button in the formatting bar and paste the contents into place.
Meanwhile, what you PM'd me indicates you have 802.11r enabled... this doesn't work well with some devices. Turn it off and try again.

The networks here are wrong. Should be lan only, not lan wan.
Yes, I changed it, still 2.4g doesn't workPreformatted text
Can you elaborate on this... how far are you from the AP, what are the specific symptoms that make it clear the signal is 'disappearing'?
I can connect to 2.4G from very close to the router, which is about 25 square feet. 25 square feet are lost beyond signal feet. 5G signal is good up to 1200 square feet
Set your country code... that doesn't appear to be configured.
I did, sir. Not yet.
I understand need to revert to stock firmware.
The country code can be set in OpenWrt.
You may be best served by resetting your device to defaults, then setting only your basic wifi settings (country code + SSID + encryption type + password). Then test again.
Best option is to reset to defaults... make a backup, but don't restore your backup at this point.
settings basic wifi settings (country code + SSID + encryption type + password). Then test again but no improvements.
