to /etc/config/wireless's wifi-iface, but it made no difference.
Also, I'm having another issue where an Android TV gets disconnected after a few minutes after it goes in standby mode, which didn't happen before switcing to OpenWRT from the stock router firmware. Again, I have to manually go into the TV's settings and click "connect to WiFi" before it goes back online.
It seems there are lots of problems reported on this forum with such devices.
I take it that you have set the country code and tried experimenting with different channel widths?
You could also try latest snapshot to see if that helps.
The RT3200 is WiFi 6 and only £80 on Amazon now. Its WiFi is 100% stable for me (and many other users), it supports 160Mhz width on 5Ghz, has fast processor and lots of ram. Just thought I'd point that out! It was also ultra stress tested with many client devices and it survived that. I will try to find the post on that.
Hey everyone! Thanks for all the helpful messages.
@Lynx thanks for the suggestion, but that router costs 3x the Archer C6 that I have and atm I do not need to upgrade. I will totally consider that make in the future however, if it has good compatibility with OpenWRT . Even though, before buying this router, I specifically searched for it on OpenWRT's website/forum and didn't found particular issues. Guess I was a bit unlucky.
Anyway, @OldNavyGuy , I did what you said and it actually works! I created another 2.4GHz-only network and both the tablet and the Android TV do not lose connection anymore. And now the question is - do we know why this happens? This is a good workaround; isn't it possible to fix the main issue since we know where to look?
Also, yes; I tried experimenting with different channels, channel widths, country codes (both my country's, the default and the global ones)... Without any difference. The only thing that made a difference was a separate network.
Thanks again! This does not feel definitive, but at least it works
