Thanks jgdoherty - I thought my husband was going to have my head on a spike when he got home from work and found our download speeds were on occasion worse than before. Now I can tell him to hold the divorce papers for a while.

The wi-fi is holding up beautifully. We use a lot of wi-fi devices, sometimes as many as ten at a time, and have always suffered drop-outs between them and the router. At the moment, wifi connection is speedy and stable.
