Is this a wireless LAN that's dropping, or is it a wired connection plugged into a LAN port on the router? Or, is it both?
One thing you can try right now is upgrade the firmware on router if newer firmware is available.
It matters not how straight the gate,
How charged with punishments the scroll,
I am the master of my fate;
I am the captain of my soul.
