I am using
relayd similar to the instructions here: https://oldwiki.archive.openwrt.org/doc/recipes/relayclient
on a TP-Link TL-WR841N/ND v9 using openwrt-19.07 branch (git-21.044.30835-34e0d65)](https://github.com/openwrt/luci) / OpenWrt 19.07.7 r11306-c4a6851c72
In essence, at random moments of the day (0-4x/day, let's say), internet access for the wired devices behind the bridge becomes flaky and slow, to the point of being unusable until I restart the router. Access to the web interface as well as SSH remains largely intact (but is slowed down by DNS lookups failing).
The problem has existed since at least the official 18.x releases and exists despite nightly reboots, but I have recently noticed that
ifup stabridge fixes it immediately. Still, I get a bit tired of issuing this fix multiple times a day, and it's certainly disturbing in video conferences.
How can I proceed investigating this?
I have noticed that issuing
ifup stabridgerandomly does not seem to negatively impact any open connections, so might it help to run that in a cron job every (minute/hour/...)?
