Vista internet drop after some time (need help!)

My machine keeps dropping the internet after an hour or so of us
online. It normally requires me to restart the laptop to get th
internet to function again. What is strange is that it still sees m
network name but does not allow me to reconnect to it when the interne
drops. I went to device manager and disabled and re-enabled the wireles
and it brought it back to life.
What could be causing this, and is there a fix for it? My dads lapto
with vista doesnt have this problem. I have already tried turning of
the power save feature on the wireless and also unchecked Qos, ipv6, an
both link-layer topology in the wireless network connection properties.
Also, I just did a fresh install of Vista to see if it helps and n
dice. Also updated all the windows updates, even to SP1 and still n
dice

I have an Alienware aurora m9700 duo core 2.0 ghz, 1 gig ram, 80 gi
HD, Realtek 8185 Extensible 802.11b/g Wireless Device, Vista Hom
Premium. Any help from you guys is greatly appreciated

below is a copy of my ipconfig after the internet drop if this can hel
you guys diagnose my problem
