Yep - using wireless.  Tried playing with ariels to no avail. 

I'm running the only wireless network I can detect in the area so no issue there either. 

The only thing that appears to make a repeatable difference is is the Slimserver software itself.  I've gone back to 6.1 and not had one dropout since.  I can only assume that the 6.2 code still has a few bugs that are doing something untoward to the server itself.  I believe that 6.2.1 will be out shortly, so I'll try that.  If this still has a drop out sort of issue on my system I'll investigate Slim Device's bugzilla and raise something if its not already been done.

Stuart.
