@SecretSquirrel You can set the same SSID between both devices... devices will roam between them. Fast Roaming will not work... but the devices will roam on their own.

@michalmit The TAG itself doesn't completely relay to the Windows Laptop unless the NIC configs have the tag set. You will need to trunk that port to VLAN 2 for your laptop to be completely on that...

@dognose Doesn't all that relay through Radius/NPS?

@dyo You would need to use Policy Based Routing: https://www.tp-link.com/us/support/faq/2134/

@jasonridesabike Have we also confirm the test device was connected to the 670 during the test also?

@jasonridesabike Just to circle back around... Have you confirm the signal strength of your test device AND the band it was testing on, during the test?
