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?

hmelder commented 2 years ago

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?

turgu1 commented 2 years ago

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.
