But as soon as they are plugged into the switch the radios on AP's are turned off which is a default behavior when they can't reach internet.

Not sure if I understand it correctly, do you mean that the AP250s still broadcast WiFi signals but just clients connected without Internet access? If yes, what IP addresses do the clients obtain from the AP250s WiFi (either 2.4GHz or 5GHz)?

From the screenshots you provided, it seems that one AP250 is connected to Port2 of the switch, how about the other AP250?

Could you please also provide the LAN->Profile config for checking?

I think the switch is stripping tags from VLAN1 traffic as the AP's use tagged VLAN1.

Yes, it will remove the tag from VLAN1 traffic as VLAN1 is the default VLAN on the switch and it's untagged.

Any workaround so that the switch leaves tagged VLAN1 traffic as it is instead of treating all traffic on VLAN 1 as untagged.

If the AP250 can only get Internet access from tagged VLAN1, the easier way is to manage the switch in Standalone mode (without the Omada Controller) and configure the VLAN1 by selecting the Ports (connected to the AP and ISP Router) as Tagged Ports.

But if you have to use the Omada Controller to manage the switch, you may create a new LAN instead.

Here I give you an example for reference.

1. Go to Wired Networks -> LAN -> Networks, click "Create New LAN". Here we name the new LAN as "VLAN2" and set VLAN as 2:

2. Go to Wired Networks -> LAN -> Profile, click "Create New Port Profile". Here we name it as "tag VLAN1", select the VLAN2 (the new LAN created above) as Native Network and select LAN (the VLAN1) as Tagged Network.

3. Go to Wired Networks -> LAN -> Switch Settings, assign the port profile accordingly.

For the Ports connected to the AP250 and ISP Router, change the profile to "tag VLAN1"(the new port profile created above) .
