I recently purchased this avtech avc761 from Ebay.  Quite good for my needs and you can connect remotely with their ap s/w.  However, when I want to connect to the box using the browser instead of their ap s/w, I get the following error: 
  
"The requested URL was not found on this server" 
  
Is there anyone here who can point me to a link where I could download the f/w? 
  
Thanks in advance!
