Hello Morse Micro Community,

We are working with **two HaLowLink 2 APs** , each using the **Morse Micro MM8108-B2 802.11ah (S1G) radio**.

Our objective is to perform **client roaming between these two HaLow APs**. Both APs are configured with the same SSID, and the APs are connected through an **802.11s mesh backhaul**.

I would like to confirm whether **802.11k/v/r enabled roaming** is supported on the following **HaLowLink 2** configuration:

- **Device:** Morse Micro HaLowLink 2
- **Firmware:** 2.11.13
- **OpenWrt:** 23.05.6
- **Linux Kernel:** 5.15.189
- **Wireless:** S1G / IEEE 802.11ah
- **AP Configuration:** Two HaLowLink 2 APs with the same SSID
- **Backhaul:** 802.11s mesh
- **Security:** WPA3-SAE

Could you please clarify:

1. Is KVR-enabled roaming fully supported on this hardware/firmware?
2. If supported, are there any prerequisites or additional components/configurations required?
3. Is automatic neighbor synchronization between the APs supported, or does the 802.11k neighbor database need to be configured separately?
4. Does 802.11v BSS Transition support providing a preferred candidate list / candidate preference for roaming?

Any guidance on the recommended configuration for achieving KVR-based soft roaming would be appreciated.

Hi @Chaitanya

Thanks for your patience here.  
Yes 802.11k/v/r is support. Configuration follows standard configuration as per wpa\_supplicant and hostap.

I don’t believe there is support for automatic neighbor synchronization so adding a neighbor to the database would need to be done manually. This can be done with the set\_neighbor command of hostapd\_cli\_s1g.

I’m still looking for clarity on the answer for 4 - with regards to providing a “list”. But it is possible to send a BSS TM Request manually and specify a neighbor as a preferred candidate.
