@omada_user23901 Try enable the band steering and fast roaming. You can also try to set separate 2.4G SSID and 5G SSID for specific clients.

@mhoam I thought this may be a browser issue, not a router issue.

@arrmo Hi, from my knowledge, although the DDNS configuration on the router is set to the wan interface of the route, it will still end up pointing to the public IP and does not need to be specified...

@NickInOz Hi, you can consider the EAP245 V3, it supports the Mesh in standalone mode, which means you can manage them only via the Omada APP on the phone.

@vvventsi05 Yes, CPE210 is a single band 2.4G device, and it can handle 100M speed, it is definitely OK.

@Jcbolive Hi, it seems like a hardware issue, suggest contacting the support from here and applying for a replacement.
