Seems to work ok here!

Updated yesterday and I've experienced no issues so far.

Updated my two deco devices and no issues.

Good to see no issues so far but I might hold off a bit longer. My last upgrade went a bit awry.

Where should I set DNS now? In ipv4 or DHCP settings, or both?

Trend AV is blocking UDP Port Scan from the router 192.168.4.1 on several devices since update..

Still no ability to manually change the WiFi channel.......

The update failed for my Deco and now the whole thing not working. Don't know what to do!!!

Upgrade reset my LAN IP to 172.16.0.1. Previously was away 192.168.0.1. A minor annoyance to reset and reboot (twice) to get it back to normal. That, and needing to power cycle a few devices that didn't appreciate it. Luckily. My reserved ip addresses followed the network switch so I didn't have to rebuild those again.

Still problem with display of app speed of the connected devices on the guest network which do not show in the devices list. (No problem If connected on the main network)
