Trouble with wireless n and smb shares

Question

I have a bit of a per-plexer here.
I have a personal mac that up until a little while ago, ran 1.5.8 flawlessly for six months since i had it.
This included a lot of mounting my windows 7 file server and watching movies or listening to music over wireless G. Every night in fact I would fall asleep to a movie, then wake up and play some music from my music folder on the same server.
The battery would die nightly of course. Morning, charge it up with some music on.
I picked up a copy of snow leopard upgrade for 30 bucks when it was released or there about and installed it. Went fine and I continued happily using the machine for about 2 months.
Then I bought a belkin wireless N gigabit router, to replace my wrt54g. It worked alright and I continued my daily/nightly routine, watch a movie, sleep, listen to music.
However the first morning, and every morning subsequently there after I have run in to a pain-in-the-butt problem.
I awoke to find, like always, my server shares still mounted (or at least they appeared to be). But opening any of them would present a blank finder window, like no files were available.
Unmounting and re-mounting the shares would fail, with a message saying unable to connect to the PC.
So, what do you do next? I reboot. My programs close, the dock, finder, my background turns to the blue solid.
System stops re-booting... it sits here, with a plain cursor and I am unable to do anything but hard-power it off.
After a hard-reboot,everything functions normally until it hibernates or sleeps with the samba shares.
I took the router back and got a dlink n/gigabit router instead, cussing out belkin on my way to the store. No change!
So I reinstalled (I didn't even archive, i just blew it away) - installed 10.5.8 again, upgraded to SL, and connected to my wireless. I can still reproduce the issue.
So, i'm bummed, i've tried a lot of things I wont bother listing here but one more important detail i wanted to add is:
I work at a company that has blanket wireless b/g coverage using multiple access points and a controller to do load balancing and access point switching.
Recently, we got a few N access points from the provider and I set them up around the office in a new, isolated SSID on the subnet i do my work on. Using WPA2 Psk, like at home.
So, now to be fair I've got a slightly-newer mac at the office, same unibody but late 2009 instead of early 2009 (sd slot instead of express slot). I threw SL on it, and connected to the new SSID i setup and finally connected to our netapp and left for the night.
Come in in the morning and I can reproduce the issue on the work mac.
So, two different macs, 2 very different N wireless networks and 2 different file server platforms. But same prob, **** thing chokes overnight.
I have been able to reproduce this issue with a slough of late 2009 macs at the office now, as I handed out the SSID key to those with SL as my unwitting test subjects. Everyone's coming up with the same problem.
Has anyone out there run in to this? It's such a huge issue i'm surprised i can't find anymore information about it!
Thanks,
Josh

I took a look at the logs and copy and pasted a lot, these are a few before and many from AFTER the hibernation last night.
