I'm planning on building a linux wifi router. I would like to support both 2.5Hz 'b' and 5Hz 'n' devices. I have so far assumed that this will require 2 wifi cards, Is this correct?
Or are all/some (mini PCIe) wifi cards capable of allowing both g and n devices to connect at the same time?

Bullet Dodger,

Some cards do b/g/n but I can't think of one just now.

They don't actually do all three standards at the same time, its only one transmitter/receiver. Instead, they time division multiplex between the standards as required by the the associated devices.

If you want to maximise available bandwidth, you want two cards, one for g and one for n, however, they will need to be on separate subnets.
Start with one card and see if it works well enough for you.

Ok, Thanks.

I have seen cards advertised as b/g/n, but I thought they only operated as 1 or the other. I didn't thnik they multiplexed as required, but thinking about it now, it seems obvious that they would.

It is only a home router and some homes might get away with just 1 wifi card, but as I have 5 wifi enabled devices in my house I think 2 wifi cards is the way to go.

Also part of the reason for wanting an 'n' router is the 2.5GHz bandwidth seems to be getting crowded around here. Or rather I can see a lot of wifi devices that I have assumed are on 2.5GHz. Is there any way to find out what is on 5GHz and what is on 2.5GHz, using just a mac book or a b/g/n wifi enabled gentoo?

So far the plan is to use a zotac nm10-a-e mini itx motherboard.
This gives me 2 mini PCIe slots.
The PCIe x1 will be unusable as I am planning on using this case M350.

The motherboard comes with a AzureWave mini-PCIe wireless card. I'll try to setup this card, then buy a 2nd 1. Possibly intel as they have support in the kernel.

I am also wanting to make this into a 2TB time capsule.
There aren't many 2TB slim 2.5" HDD's about, but they do exist.
HITACHI HD SERIAL 2TB

Cheers

I'm pretty sure that Kismet will do most of the scanning that you want.
Apparently it has OSX support (as well as Linux).
