No Fast Roaming with EAP620/EAP615 and Omada Controller 5.1.7
This thread has been locked for further replies. You can start a new thread to share your ideas or ask questions.
I'm using two EAP620 and one EAP615 with the Omada-Controller on a Linux Machine. In the controller I've enabled Fast Roaming together with AI and Dual-Band Reporting in WPA-Personal mode.
However Fast-Roaming does not seem to work. Also when I capture the beacon frames with Wireshark there is no 802.11k or 802.11v information being sent:
Do you have any hint on how to make this work?
Dear @chbmuc,
The 802.11k and 802.11v protocol contain many function points, you may need to expand the collapsed frames to have a check.
For 802.11k, you may check whether there are function points such as Neighbor Report, Link Measurement.
For 802.11v, check whether there are function points like BSS Transition Management in Wireless Network Management (WNM).
If you see those function points above, it means the 802.11k and 802.11v information are being sent.
Kind note:
With 802.11k/V Fast Roaming enabled, we can use the 802.11k/V capable wireless client to capture the 802.11k/v packets via Wireshark.
To successfully capture the packets of 802.11k/v, please ensure the Wi-Fi is NOT configured with WPA3 encryption as its management frame is encrypted, we may fail to see the frame we need. WPA2 encryption is recommended.
Besides, the 802.11k Neighbor Reports packets can be captured when the SSID is associated each time. But 802.11v roaming packets are not easy to be captured since not each roaming contains 802.11v packets, that is, 802.11v doesn't happen when the client is actively roaming.
To view the 802.11k/V packets generated by the 802.11k/v capable clients and APs, you may filter the action packets via "wlan.fc.type_SubType == 0x000D".

@Fae Thank you for your profound response.
Link Measurement and Neighbor Report are enabled, so 802.11k should be fine. However I'm unable to find any Wireless Network Management (WNM) information. These are all the "Fixed parameters" that I have.
