When I saw it, it was due to some older Intel NIC drivers.

The drivers were updated and we never saw it again.

The default setting (when getting two Michaels) is that the AP will shut down for a while, then come back up ... so a symptom is that everyone's connection bounces.

Good Luck

Hi Scott,

Thanks for your information, yes i heard it was due to driver as well. but i just curious, if user didnt update the driver will this interfere to other wireless users ? coz, AP keep receiving the error.. so, will it be influenced to the Wireless performance ?

your reply will be highly appreciated.

thanks.
