This bug provokes udp connection “disconnect” like for example i’m getting constant hangs (like about for 3 sec each 6-10 min?) while using google meet and bc of this i can’t really use this router and have to fallback gl-mifi with last openwrt instead. So i guess i’ll need to try other dhcp client with flint or some new version of udhcpc? In the thread (url above) you could find link to github issue (udhcpc: no MSG_DONTROUTE when sending packet by adiov · Pull Request #1017 · openwrt/openwrt · GitHub) which supposedly solves the problem.
