802.11r Fast Transition

Installing and Using OpenWrt Network and Wireless Configuration
1

Hello,

I have a pair of OpenWRT devices configured as AP in my house. Both have 19.07.2 image running and want to try to configure roaming.

Both APs are connected in the same switch. Once I activate the "802.11r Fast Transition" in the wireless section, I get this options:

867×850

Some have experience with this? I use WPA2-PSK with same key in both APs.

I will really appreciate your help.

Best regards.

Make sure they both have the same entry for mobility domain. Otherwise you can leave everything as it is and it should be working.

Follow this short guide on how to configure 802.11r.

Update 02.09.2020: use Luci-app-dawn instead and enable 802.11r, v and k using the CLI:

uci set wireless.default_radio0.ieee80211v=1; uci set wireless.default_radio0.ieee80211k=1; uci set wireless.default_radio0.bss_transition=1; uci commit

See Finally got 802.11v working (FULLY) - Few pointers

Dawn requires a Release newer than 19.07. eg snapshot-branch.

That guide is out of date.

Well it is more or less still correct. Remove wpad-basic and install the full wpad (wpad or wpad-full), then enable 802.11r, configure the nas id similar on all devices and set the "Generate PMK locally"-option and you're ready to go.

@zorrua After you click the checkbox next to 802.11r (like you already did) - 802.11r just works right out of the box. Enjoy!

No need to do anything further with any of those additional options. Those advanced options are for advanced configuration and don’t apply for most people after these commits:

Thanks!

I have installed this wpad packages:

# opkg list-installed | grep wpa
wpad-basic - 2019-08-08-ca8c2bd2-3

Is it correct? Or need I install one of this?

# opkg list | grep wpad

Should work. Test it out by roaming between your APs, checking logs, and seeing what you think. :sunglasses:
