I work in a company which develops WLAN Access Points.
We connected a Nokia N91 to our AP and everything went out OK until the N91 entered Power Save mode. After entering PS mode the phone rapidly connected and disconnected from our AP for a long period of time, until disconnecting completely.
I scanned the web a bit and found out that other users encountered this problem but I could not find a reasonable explanation for this phenomenon.
I would appreciate it very much if someone could suggest a good explanation.
Thanks in advance,
