I have a WLC 4402 Wireless LAN Controller with multiple 1231 AP on LWAPP. WLAN has security setting on WPA+WPA2 with PSK share key. All computers in domain are fine, wireless connections are steady. I have a group of students use Netbook on Windows XP Home SP3 got connection and drop situation. Event ID on XP has continuous 4201 and 4202 cases, and on WLC log I have also continuous log as
*Apr 19 10:35:44.046: %DOT1X-3-MAX_EAPOL_KEY_RETRANS: 1x_ptsm.c:407 Max EAPOL-key M1 retransmissions exceeded for client 00:26:5e:eb:fd:0a
I understand XP Home has no certificate from Domain environment therefore I didn't setup any AAA server service. How can this problem be resolved? Keep trying on security combination, but no luck. Please Help. Thanks.
Attachment is WLC configuration file without encryption.
