There could be dozens of reasons:
* interference from another WLAN
* A wIPS incorrectly identifying your client connections as rogue APs
* misconfiguration of authentication/TTL strings
* WLAN set for backwards compatibility (scaling back to 80211b will cause faster connections to drop out)
* many more!...
If you could send through more information, we can make more accurate suggestions on a fix.
