You might take the newest OpenWrt 21.02 stable build.
You can see the list of newest ones in the first message.
And you need the factory image for flashing from the original OEM firmware, if you are still running that. ( If you are already running some OpenWrt image, use sysupgrade.)
@hnyman had to restart my wifi 5ghz (80Mhz channel 52 / fast roaming) twice now on the last two master builds: 18770 and 18792. Should I provide some logs (if so which one?) or is it a known issue?
edit: changed to channel 36 as I found out that channel 52 @ 80Mhz is a strange choice. Will report if it changes things
Is the 5GHz Wi-Fi not responsive or you see extremely high latency? I do see the same issue with my own custom build for my R7800. Am testing a fix suggested by @tohojo and so far after 3 days of uptime, I'm not facing a much issue as I used to, for recent builds. I'm on openwrt 21.02 tho. Will monitor it for a week and week how it goes. The suggested file link can be found here.
Edit: Provided the link to the suggested fix.
What I found is that if the 5GHz Wi-Fi is on congested channel (typically that would be 36 and 149) the issue will be more apparent. Unfortunately the others are DFS channels, so even if you configure the regulatory domains and set it to auto, many times the channels will go back to either 36 or 149.
I have not ran into trouble by myself, and as there are no special source code changed in my build regaring the basic wifi functionality, it better to discuss in the generic R7800 thread (or in a ath10k-ct thread).
If you set it too high you might run out of memory as this limit is per socket. But the R7800 has quite some RAM for this and usually you don't have a lot of sockets open on the router, since there are not many services running on the router that communicate with clients, unlike a webserver for example.
I've been using it for over a month now and it works fine. I did increase it step by step until it worked for me. For some doubling 524288 might also work, but it really depends on the amount of traffic that goes through your router.

The build should be equivalent to the 21.02.2 release that was tagged today. The release will likely happen during the next few days, once the buildbot build has completed the build, the release docs have been finalised, etc...
@hnyman not sure if you're aware but i think your feeds.conf.default patch doesn't apply any more, the master file was changed in late December to use src-git-full.
@hnyman was thinking of implementing some type of module or status to display the presence of pstore directly in luci.
Would be an interesting feature to add...
Something like
Give user notification if a pstore is present (aka system has crashed here is the log)
Advise to publish it and provide a download button
What do you think? Do you have suggestion / opinion on this feature?
