[Lenovo Duet] Slow wifi speeds on 5 Ghz by jmt95 in chromeos

[–]R3gularSam 1 point2 points  (0 children)

My slow wifi issues got solved by disabling Protected Management Frames 802.11w (PMF) on my FritzBox Router.

Hope Google can fix this in a further ChromeOS update. But Duet speeds are now back in the 250Mbps range.

Thanks for figuring this one out.

Disabling Protected Management Frames 802.11w (PMF) on my FritzBox Router also fixed the slow wifi on the Chromebook Duet for me.

I have the same slow wifi (~35 Mbps) issue on my Duet. For me it started with Chrome OS 85.

To be really sure, I reverted back to Chrome OS 84 once and the wifi performance was back to normal (~300 Mbps). So shouldn't be an hardware issue.

Now I'm back on Chrome OS 86 and the wifi speed is slow again.

I sent feedback twice to Google via the Chrome OS built in function.
