Connecting two wired networks wirelessly?

[Joe]

My house, although much less colorful:

[Internet]
    |
[Brother's Box]
    |
[Wireless Router] } }    { { [Mom's Laptop]
    |
[My Switch]-[My Laptop]
    |
[My Box]
    
    

[Mac 1]
    |
[Mac Switch]
    |
[Mac 2]

Basically, I want to connect both of the above networks, but using wires is simply not an option. Is this possible? What hardware will be needed?

Obtain a second wireless router and replace the Mac Switch with it. You will then put that second wireless router into bridge mode, connecting it to the original wireless router. There's a lot more specifics, but that's just the basic idea.

Mmk. That's what I was thinking but I wasn't sure.

Or if you could turn one of the macs into a router and put a wireless card into it, that works too.  I don't know what macs are like as routers. 

Or, you could get a wireless card for both macs and throw the switch in the trash..

[Joe]

That'd ruin the point, though! . And apparently Macs are alright at routing, at least to other Macs. I don't know how Airport cooperates with standard wifi.

I do not understand your diagram.  Are the macs not connected to the internet?

It doesn't look like they are.  It seems to me that he wants to connect them to the internet via his network.

iago is correct.
