Connection to Access point periodically lost

I have recently gone through the process of setting up a wireless network in my home and I found that a lot of routers and access points 9especially in the wireless N and MIMO categories) have that same problem. Are you trying to go with wireless N? If so then you must be careful what you buy because cross brand connections are not always compatible and also most N routers on the market today do things like drop the connection for no reason. I would recommend the apple airport if you are looking for a good router in the N category. I know they are expensive, but after trying out 5 different routers including all the top brands, I came across the airport and haven't had a problem since. This issue you are having is likely a problem with the router itself.
