SW2007 Network save question

I've made the move to 2007 on one desktop pc and one laptop for testing.
I've been working on a small self-contained project (no toolbox files, etc.)
located on the file server, as usual. From the desktop pc I'm connected via
wired ethernet and have had no major issues as of yet. From the laptop, I'm
connected via 802.11g wireless. Today from the laptop working on these
files I would be presented the "lost connection" dialog when I tried to
save. This of course would force the save-as dialog to pop up which I would
escape out of. At that point, a second attempt would save the files just
fine. Very sporadic but still fairly repeatable. I checked the connection
to the network each time and it was fine. The wireless router is located
literally 30 feet away in a conference room and never presents connectivity
issues. I'm wondering if something within the file handling of '07 has
changed to cause it to flake out over wireless. I can check this easily
enough by opening files at home over wireless but I thought I'd ask the
broad question first...

Has anyone else noticed any flakey network issues, in particular via
wireless while using '07? Just curious.
