[Dxbase] Internet Cluster Question

[Crownhaven]

I have recently started connecting to the DX Cluster via the Internet.  
I am finding that about every four to six hours, sometimes more, 
sometimes less, I seem to drop off my node.  I get a solid string of 
Keep Alive Feature Is Active but no spots.  If I close the window and 
open it again, I am connected and the spots start coming.  I switched to 
the Internet due to unreliable RF packet connections.  This isn't much 
better.  What am I doing wrong if anything?????  Or is this just the way 
it is??????
