@Alam0786 I use WhatsApp all the time with a full Omada stack, with no issues. Are you using URL filtering? Which DNS servers are using?

At this point, I know you can configure APs in standalone mode with your phone APP. Is there going to be StandAlone Configurations through your phone with routing and switching? Or at least a Mobile...

@jbl-tom Could try the ARP list. Firewall> Anti Arp Spoofing> ARP List That may help.

@RobertMEF 10 seconds is my starting point. It's been a good number for me so far.

@SCBJr Have you confirm the LED is enabled in the controller? Or even maybe toggle it on/off?

@RobertMEF So here's my main question... Can you confirm you will be saturating 1G speeds while in production? Also, have you bypassed the Omada router and tested the ISP speed connected directly?...
