I have a WLAN using the Linksys WAP54G access point implemented with the WPA-AES security mode. The group renewal key is set for 3600 seconds. I have the following wireless adaptors attached to the access point.
Linksys WPC54G Netgear WG-111 DELL 1350 Mini-PCI D-Link DWL-G122
I've tried using TKIP but the D-LINK adaptor would drop off the WLAN during the rekeying periods. No matter what time limit I set. The access point and adaptors are running with the latest and greatest drivers and firmware.
