constant disconnection/reconnection between Netgear MA401 AP and SMC2632W V.2 client

	I'm deeply sorry for the second message, but I felt I left out some
important information. When the SMC client disconnects from the Linux
WAP (using the netgear MA401 with hostap driver), the driver displays
the following data...

wlan0: 00:04:e2:46:c0:07 auth (alg=0 trans#=1 stat=0 len=6fc=00b0) ==> 0
wlan0: 00:04:e2:46:c0:07 reassoc (len=23 prev_ap=00:30:ab:09:4f:9e) =>
0(0) (OK, old AID)
wlan0: 00:04:e2:46:c0:07 auth (alg=0 trans#=1 stat=0 len=6fc=00b0) ==> 0

Apparently, every time the client disconnects/reconnects, a coresponding
"reassoc" is issued. I thought perhaps this debug info would be useful.
