If you are running DHCP on everything plugged into the switch, then my guess is its the Archer A7 router is also on the 192.168.0.1 address that is likely being used by the Omada router.

Try removing the archer and see if that does it, if so re-ip it static to 1982.168.0.200 or something else..

@xmtr34  One of the options. Assign addresses to all your devices manually from 2 to 50 for example. And DHCP will allow a range of 51 and above. The sequence is just that.

Thank you both. Ill look into the Archer A7 side first as thinking about it, I do seem to be running into the confliction issues when this is connected. Otherwise, it is like you say I guess and manually configure all devices statically on the network.

Thanks again.
