[Novalug] pauses in wireless connection

Jon,

What you're dealing with is likely a TCP timeout.  After some period of
inactivity, it's closing the connection.  For SSH, there is a keepalive
setting you can change client side that will, well, keep the session alive.
To fix this for all applications, you'd need to look for a setting within
the router's admin panel itself.

Good luck -- I know nothing about the ActionTec itself as to whether this
setting is user-serviceable.
