[ANSS-netops] reftek suddently stops streaming

When you upgraded the software in the refteks did you also upgrade the
PLD's on 2 of the boards inside the unit?  some of the function in software
will not work until those are either replaced or reprogrammed using files
from reftek.

Also one other note with the "dsl" routers  I have had issues with the
linksys (cisco) small routers not forwarding UDP packets.  They work for a
while and then just stop.  when they are rebooted the start working again.
I have converted to the netgear wireless routers that are using open source
firmware and turning the wireless off.  It seems to have stopped the issues
we were having with UDP packets on the Q330's   The model number of the one
I am using is:  wgr614 and it is about 50.00 at CDWG
