Do you know how the group cipher is configured? Is there any special
configuration for it or is it supposed to be TKIP for everything?

What firmwate version are you using?

Could you please send the configuration file you are using?

Hmm.. That group cipher 1 would be WPA_CIPHER_NONE which is not
allowed.. Odd that wpa_supplicant allowed the negotiation to go this
far. Own WPA IE above uses TKIP as the group cipher.. I will need to go
through the code to understand how this could happen.
Which version of wpa_supplicant are you using?
