Show HN: Undocumented Qualcomm mesh topology 802.11 frames

https://david.weekly.org/blog/2026-04-09-orbi-mesh-beacon-topology/
2•dweekly•6h ago
Netgear Orbi WiFi 7 nodes broadcast a Qualcomm vendor IE (8C:FD:F0) in every beacon that contains the parent node's MAC address. I caught a live star-to-daisy-chain reroute and confirmed it against three APIs. Undocumented, not in Wireshark, field map and open questions in the post.

Pretty neat: you can see the whole layout without even being associated to any of the APs!
