Question

Voice handsets on a city council WLAN drop briefly during walks between APs. Controllers have 802.11k/v/r assists enabled, but several older laptops and phones lack those client features. What is the issue?

Accepted Answer

Feature incompatibility: clients without 802.11r/k/v support cannot benefit from those roaming assists the network expects. — Network-side k/v/r doesn’t help a handset that never implemented those IEs. That’s feature incompatibility on the roam path. Expect uneven roam quality until clients support the assists—or design for the lowest common capability.

Answer

Every 802.11 client automatically supports 802.11r/k/v as soon as the controller enables the checkboxes.

Answer

Missing client roam features always mean the fiber uplink to the core switch is down.

Answer

Disabling SSIDs on 2.4 GHz is the only remedy when clients lack fast-transition support.
