Re: 2 Laptops, only 1 can be on WAP at a time

I haven't tried to follow the whole thread, but 12 machines shouldn't even
touch a good cable modem connection. Ours is 5mbit and we have at least 7-9
concurrent machines and we don't even notice it. Let's face it, you're
sharing the bandwidth all your neighbors anyway.

My first step would be to get ONE working environment and then figure out
where to go from there.
