Problem with 5040

I appear to be having a problem with sending / recieving shows with my 5040. I accept a show, or send a show.. and some time later (between 1 week and 36 hours) all Network activity on the RTV stops. At this point DVArchive can not see the RTV, and the RTV can not see DVArchive. I can not ping the RTV from my computer either. I end up rebooting the RTV and everything comes back to normal... (Except the last time I did this, I lost the show I was transferring...it just disappeared).


This all started about the time I upgraded to a 200GB disk. Which I had to download a new RTV Image to get to work, and re-configure all of the network settings on the RTV. The RTV itself has a static IP (just like before), and nothing on my router has changed.


Anyone have any idea's why this is happening?


Thanks!
