PCs lose access to WD Sharespace shares at random intervals

I have two network-based laptops, one with Windows XP, the other with Windows 7, on which I have installed WD Anywhere and which are backing up for the first time to my newly purchased 4 TB WD Sharespace.

After a random interval, the shares go offline.  Disconnecting and reconnecting them with “net ue” fails.  When this happens, one can’t use the  web GUI to read the CIFS log.  If one is connected with ssh, trying to look at smbd.log under /var/log/smbd also hangs.  The unit no longer appears to respond to the power button and trying to use the web GUI to shutdown or restart the box also fails.  Until I learned how to use ssh, the only way I could “fix” this was to disconnect and reconnect the power. 

However, with ssh, I can see a bunch of smbd processes when the box exhibits this behavior:

I’m not sure what’s up, but stopping and starting smbd seems to fix it, for a while.

Has anyone else seen this?  Is there anything that can be done?

I managed to “solve” this on my own.  The onboard wireless adapter in my wife’s new HP G60-63OUS Windows 7 machine appears to be the cause of the issue.  She’s been having intermittent connectivity issues.  When I disabled the onboard wireless adapter and hooked it up to a Netgear  wg602 v4 access point then the problem went away.  The access point had been originally purchased for an “internet savy” DVD player, good thing I had it laying around. 

Anyway, I haven’t had to restart samba since I hooked this puppy up and both laptops are sending files to be backed up.
