Connecting to the AP fails repeatedly with the following error: "wifi:Group & Pairwise ciphers must be AES-CCM for PMF"

How is your wifi network configured for security? (WPA2, WPA3, RADIUS, PMF ? Other parameters beyond ssid and password?)

Is PMF disabled on your wifi access point?

I've checked the preferences of the AP and sure enough PMF was enabled. Thank you for the quick response :)

Which security protocol are-you using, is it a router, what model?

Answer 4 · 2022-02-20T15:07:48.000Z

It may be that the PMF on your AP is using an opmode different than AES-CMM (like AES-GCM, CNSA, SAE-AES or others). Please try to find which one it is using.

It works now. My router is a Vodafone EasyBox 804.
