Network questions
piratePenguin:
We're getting (wireless) broadband in a few days/weeks (at long last), so one computer (probably my brother's Windows computer) is going to be connected to the internet, and it'll be sharing the internet connection with at least my GNU/Linux computer and a few Windows laptops.
I've been thinking of getting a wireless access point, but I have a few questions first:
Is it possible (I think it is. Just making sure.) to have one computer connected to the net, with a wireless card, and sharing the connection, while the access point is connected another computer?
What wireless access point should I go for (must be G. If it works with B too, that's a bonus)?
If I need a wireless card for my GNU/Linux box, which should I go for?
I'm kinda tempted to go this route. Is that a bad idea?
Cheers!
PS: I'm too lazy to google this stuff. I usually would (google it I mean), but I don't have much time (exams all week) and I wanna get any stuff I needa buy sorted ASAP.

Not that I know of...but why would you want it like that, anyway? It'd be really messy. An access point isn't connected to a computer per se - you plug your modem...oh wait, you don't have one. In this case, you don't need an AP at all -just two wireless cards in the computer recieving the connection. Windows can share the internet from one card to the other via the network.

Don't get one - it wouldn't work. You need two separate wireless connections to do what you want, which an AP doesn't have.

The gold standards for Linux wireless are Orinoco and Aironet-based 11b cards. The drivers come with any distro. If you need something USB, Linksys WUSB11 works with the wlan-ng driver (this is what I have set up).

You can, but it's quite a lot of work. In your situation, you can use a Linux box with two wireless cards and iptables to achieve a similar effect, though it won't be an official access point. That's probably the best way for you to go.
See http://linux-wless.passys.nl/ for all compatible (and non-compatible) Linux wireless cards.

We want a wireless LAN, so we can share files and that, and share the internet connection.
I don't see how two wireless cards in one computer can do any of this. Do they not need an access point to send stuff to?
There's two laptops in the house atm, and both have wireless G support. Don't I need an access point to get them networking wirelessly?

Would one wireless card not do the job?

Thanks. Was looking for a list like that.

No. I don't have an AP and my network is fine. You have to set the cards in "ad-hoc" mode (easy), and it works.

No...a wireless card works exactly like ethernet without the wire. You can't have one ethernet card connecting to a modem and a network at the same time, can you? ;) You need to have one picking up the connection, and another that sends it to your home network.

I think I can do that on the Windows laptop, but I don't have a clue how to do it on the Apple powerbook with Airport..
Can it be done with one Windows laptop and an Apple one?

Yea I suppose. But I dunno what way this wireless broadband works. It could (I think) plug into the computer via ethernet, and send it to the wireless network through one wireless card. That's the way I was thinking it'd work. Or it could (I think) use a wireless PCI card or USB device, and then send it one to the wireless network via another wireless card.
