Hold on there: WPA3 connections fail after 11 hours

"My conclusion: this entire ecosystem is deeply cursed."

iwd is slick as hell. I use it with systemd-networkd and it's so smooth.

There's fantastic support for all the weird ways to connect: wifi-p2p/direct, ad-hoc, Device Provisioning Protocol (DPP/Easy Connect), Shared Code Device Provisioning (Pkex). Good debug tools like initiating roam to.

It's nice that iwd does less; it just gets wireless connected. NetworkManager does so much, and somehow it's never sparked joy. I've spent time on connman and that was fine enough. I've managed my own wpa-supplicant configs, which worked but was clunky. Iwd has really been a joy to work with for me, so clear & direct, with easy config files & a very pleasant little tui/cli.

Systemd-networkd has also been quite simple & direct for me, very configurable. But that's another story.

I discovered it on arch. It's a perfect companion to bluetoothctl, and far better than what I had seen on Linux before

I can get some decent speeds with the standard wifi card in the Framework 13 (Intel) and the new U7 Pro AP.

Intel(R) Wi-Fi 6 AX210 160MHz

6GHz channel (mandatory WPA3). Intel iwd instead of wpa_supplicant (though it worked okay).

There is a followup post saying that the module is disconnecting from the network after 11hrs, the cause seems a bit murky (I'd say probably a firmware issue but haven't looked in to it at all)

On my home network I have WPA3 disabled because so many devices seem to do really badly at fast roaming between APs with it, so it's WPA2 everywhere for me. Someday?

This is literally the only report I've seen of someone who got 802.11r Fast BSS Transition working with WPA3. https://forum.openwrt.org/t/802-11r-wpa3-does-it-work/135041...

I've seen tons of reports declaring that it just doesn't work & isn't expected to. It was a shock seeing a report that it does work!

Interesting. Hope that means it's within the power of the AP vendors to fix it.

In the meantime, WPA3 is required for 6 GHz -- so I guess we just sit that band out.

Not so fast:

iwd doesn't even work properly with wpa and wpa2:
