2. Is it possible to use the 6GHz band as another 5GHz band? I can't find that option in Deco App or web admin page. This feature is important since 6GHz is not allowed in some of the areas.

Deco BE85 supports MLO Link and it has two options: 2.4+5+6 Ghz, or 5+6Ghz.

I think you can enable the MLO network with 5+6Ghz. In this way, for the device that don't support 6GHz, it will only use 5Ghz when connecting to the MLO network.

 

R: Does that mean if the device does not support 6Ghz but supports dual 5G Band MLO, when the device connects to he MLO network with 5+6Ghz, it will downgrade to 5G+5G automatically?

 

 

1. For the IPV6 internet,

Do you mean the android phones or tablets couldn't get IPV6 addresses from Deco BE85?

Can I have some screenshots of your IPV6 configurations?

I saw some users mentioned before that Android does not support DHCPv6. It is suggested to use SLAAC + RDNSS.

Have you tried this Assigned Type?

 

R: My deco is running under Access Point Mode, so there is no option to change the ipv6 settings. I have other old Wifi5/Wifi6 wireless routers (2 of them are also TP-Link products but not the Deco series) and none of them have such issues under Access Point Mode.
