@rainbow6 Normally, the WAN IP is assigned by ISP directly, maybe you could check with ISP whether they are able to provide a fixed WAN IP address for you, a public one would be perfect. It is also...

@Omaryasser Hi, you could try to change the DNS server under Advanced>network>internet>WAN interface, such as 8.8.8.8/8.8.4.4

@Tazcom Have you ever checked whether there is a power saving mode on the Archer VR600V? maybe it could be disabled.

@chinkung Just out of curiosity, if you unplug Deco M3W, will the connected numbers display again on the APP?

@Ansonli0005 Deco does not support separate SSIDs but you could set the main network to work on 2.4ghz only, then the guest network on 5ghz only.

@InderDhindsa Hi, No it is not acceptable and the backhaul only works when Deco units are under the same Mesh network.
