I have more than 60 wifi clients online and working fine, including Samsung tablets and phones. I have two Samsung smart monitors, an M80B from 2023, and a brand new Odyssey G7 (G70D) that I just purchased and attempted to set up this week.

Neither of these Smart monitors are able to connect to WiFi, both seem unable to get DHCP, both can see my SSID and show it recognized as 5Ghz. The M80B was previously connected to the WiFi on the same Omada gear a while ago, but I don't know how long ago as I haven't used the smart tv aspect of it in a while, just the computer monitor. The G70D has an ethernet port so I was able to connect and update to latest firmware that way, but it made no difference. The M80B is wifi only so I cannot check for updates. I can stand next to either, open SmartThings app on my Samsung phone with full wifi signal, start the setup process for the TV, and it fails in the same way as if I try and add the WiFi directly from either smart monitor.

I've tried to get packet captures on the closest access points but don't see anything for either monitor's MAC address sending or receiving.

I have a flat network with single default VLAN 1 with DHCP enabled (via ER707-M2). There's nothing logged for either mac address either.
