Hi, 

i'm using OPNsense on a NUC with a SG2008P and 3 EAP650. 

Since i use the EAP650 access points All Devices which use randomized macs have a long connection time because for the first 10 to 15 seconds there is no internet. 

My Android Devices warn "no Internet connection" and asks if i want to stay connected anyways. My iPhones Just drop the connection and use mobile data. 

Before i used the EAPs i had a wifi Access Point (Fritz) on an untagged Port and there were absolutely no Problems, so i'm afraid that Omada is the problem here. 

I think it's not a DHCP issue because the devices get an IP instanly. If i disconnect and reconnect with the same Mac address, internet is instantly there.

Are there any settings to prevent this behavior? Switching to static MACs is not an option. 

Edit:

I think it hast to something with Ipv6 and Router Advertisment, because in my guest VLAN with public cloudflare dns, the connection works instantly too. 

Is there something that delays the Router advertisment? 

Here is my wifi config:

Thank you very much :)
