Thanks for the reply. I am a home user at home. I did the tests at GRC.com and my system did fine, but I don't know how aggressive or imaginative their attack was.

Re the WEP, can you recommend specific settings, ie 128 bit encryption and some of the other choices they offer?

I'm not sure if I can afford the $300 box at this point. I would peg my paranoia level at 3 or 4 on a scale of 1-10.

I'd like to take reasonable measures without spending a bundle.
