I have never used ndiswrapper so this advice may not be fruitful but it
would seem to me that commands such as...

ifdown wlan0
ifup wlan0

might be useful

also - similar but different...

/sbin/service network restart

would likely obviate the need to reboot.

Anyway, assuming that the signal strength is good enough to maintain the
connection, having it drop off the network is a drag and not indicative
of reliability.
