When access point support shipped in v26.01, covering a whole building still meant pulling Ethernet to every AP and living with clients briefly dropping as they moved between them.
v26.06 closes both gaps. 802.11s mesh lets the APs form their own wireless backhaul, so only one node needs a cable. 802.11r/k/v roaming hands clients over in under 50 ms instead of a full re-authentication. Fast enough that a voice call doesn’t notice.
The part we’re most pleased with is the automated regression test behind it: three virtual nodes, a client, a forced roam, and traffic that has to recover. If a future change breaks roaming, we find out before you do.
We wrote up a complete three-node configuration with the reasoning behind every setting: https://www.kernelkit.org/posts/wifi-mesh-roaming/
Configurable over CLI, NETCONF, RESTCONF, or the new web interface, and it runs on hardware like the Banana Pi BPi-R3.
