Building a wireless router

Would one wireless card in it be enough?

If I wanted, could I use two without any interference?

(Hm, now that I think further, I'd probably use a non-wireless NIC for connection to the modem, just one wireless card then, right?)

yes and yes

Unless you have needs a normal wireless Cable/DSL router is cheaper, easier, smaller and uses less power.

Thanks.

That's no fun though ;)  And I already have a computer running 24/7.

Okay, back from vacation.

I've scooped out a cheap wireless card I can use.  I have a question, how many bytes per second can a 333 MHz processor handle?  I read (in the Linux kernel documentation, IIRC) that 10 Mbit/s is enough to swamp a 100 MHz processor.

I will be using FreeBSD.

If I somehow set things up to pass data directly between the NICs, how much data can PCI handle?  133 MB/s according to Wikipedia.  That'll do, as I have no better options, and my cards use 802.11g which runs at a theoretical maximum of 54 MBit/s.  My Internet connection runs at around 10 MBit/s as well, and I don't transfer large files over my LAN very often.

Many; depends; what do you want to do with them?

Can't do that

133 MB/s according to Wikipedia.
33.333 MHz and a 32 bit bus, but that's the raw speed; you aren't getting that in real conditions, but you can get pretty close... if your network card supports it.
