Connecting to the network

I have been connecting to my companies network utilizing
the D-Link DSB-650 for 2 plus year. Lately I have to do a
hard boot as many as 6 times before my laptop will
regonized that a network exist. I can be connected, and
shut down my computor, the right way, and without touching
a cable when I start my unit back up latter, it will not
connect to the network. Why? What can I do to fix.
