How about a mesh strainer?

of wok's being used, but can't find the linky ATM

Subject: Re: [TriLUG] Dual Network Question

I do have the wireless secured with a 128 bit WEP key, and my admin login
isn't "admin:admin", but it is true... now some of the services I am running
on my network are exposed to the wireless devices too. A few close friends
of mine have my WEP key, but it'd be nice to be able to provide something
like limited access if no WEP key is provided, or total access if the
correct one is - but I doubt I can do that with a $30 D-Link box. But since
they are so cheap, I guess there's nothing stopping me from buying another,
and setting it up with the main network as the "ISP", connecting through the
WAN port. 

Here's a project for summer: what would it take to be able to pick up my
wireless signal from about 5 to 6 blocks away, in a slightly crowded (trees
and houses) neighborhood? I'd be great to have access to my desktop from my
laptop while sitting at the pool. Would a pringles can on the roof pointed
at the pool take care of this?

Regards,
