One device rejected, requests wrong WPA group cipher

Fri Nov 22, 2024 12:48 pm

Hello,
I have a wifi compatible xmas light which can be controlled with a mobile app and that is rarely reachable. I found this strange error in the logs, but I didn't find any useful solution on this forum or Google.. I assuem the ciphers are correct in the security profile, but I might be wrong.. Should I set "aes ccm" as Group Encryption?
Setup: Capsman router is a RB4011 with vlan filtering. 2 cap devices are hap ac2-s, ROS: 7.16 stable

I would at least start only supporting wpa2-psk (with aes). Just out of security perspective.

Thank you for your replies!
I added tkip encryption, and removed WPA PSK, not the error message changed..

D8:1F:12:9D:EF:46@cap3 rejected, does not provide suitable security method

Most probably it requires WPA with tkip... I will try that out too.
