All you can do is set the wireless to auto channel (give a few minutes to find a good channel), country to your country code and leave at that.
if your wireless disconnects, use wireless-schedule in the repo to start and stop the wireless when not needed or a custom script to monitor connection and restart if need be.
I would report this issue to the openwrt github repo, as its RC release there will be issue or mistakes from the dev team, im just a contributer nothing more.
Problem does not occur on TL-WPA8630Pv1 which is QCA-based running 21.02.0RC4, so the problem seems to be MT7xxx related.
Maybe it is due to the lack of igmp-snopping support in hardware of the MT7530-switch? See (1) and (2)]
The question remains: why is the discovery of Alexa devices now broken?
UPDATE:
The problem was related to a broken umdns-daemon in connection with seccomp.
I discovered the root cause when my dawn-daemon couldn't see other dawn-nodes on the same network.
Errormessage was: daemon.err dawn[x]: Failed to look up test object for umdns
cd /etc/seccomp
mv umdns.json umdns1.json
sync
/etc/init.d/umdns restart
After applying the fix to my Mi Router 4a Gigabit Edition and rebooting the router, my Echo-speakers were visible in Spotify again and the Sonos-app found the Sonos-speakers again.
You can downgrade from snapshot versions, but config will not be preserved and will get a warning when attempting to upgrade - you will need to force upgrade, but take a note of config you have, as you will need to manually change again.
is wireguard working fine for you on v19.07.8? For me it's not working - it cannot send back packets, handshake cannot complete. Previously it was fine...
Yes, just save your config System>Backup>Generate Archive and it will generate all of your configurations and use the config and upload it to your new firmware but I recommend to recreate a new config for the latest firmare like RC4
Downloaded this image and before upgrade it promped:
Device xiaomi,mir4ag not supported by this image Supported devices: xiaomi,mi-router-4a-gigabit - Image version mismatch: image 1.1, device 1.0. Please wipe config during upgrade (force required) or reinstall. Reason: Config cannot be migrated from swconfig to DSA Image check failed.
The uploaded image file does not contain a supported format. Make sure that you choose the generic image format for your platform.
Should I proceeed by choosing "force upgrade"? I'm on 19.07.8.
Hello,after Uprading my Mi router 4AGE from 19.07.8 to official 21.02 My PC can't access through internet even in 5G/AC WiFi network,after rebooting it the internet is back but if i reboot it again the internet access is gone again,what should I do?This never happens in 19.07.8
I have 2 4a gigabit as dumb APs on 21.02 working great with seamless handoff. Any way to provide custom DNS servers to clients in this mode? The ISP router acting as DHCP doesn't allow changes.
