[solved] (how) can I use my laptop as a router for other computers?

First of all, I have to admit that I do not know too much about networking. Just enough to make the simple things work properly.

I have a laptop, which accesses the internet by wireless lan. The router is in my downstairs office. So far so, good, I have a media computer (both running Arch) in my room upstairs, intended to watch dvds or internet tv on the tv screen.

Connecting this computer to the downstairs-router by cable is not possible. Now I wondered, if I really needed to buy a wlan-card (any suggestions which one works well with linux?) or if there might be an (easy) solution using my laptop as (sort of) a router, connecting them by cable and establishing a lan connection between both of them.

Is it possible, to get internet access on the media computer that way, without to much effort? And what do I need to do to get it working?

They say if you reverse play a Windows CD you can hear satanic verses... But wanna know what's even worse? If you forward play it, it's gonna install Windows on your system!

For a wireless card, I used to use a card with an atheros chipset and those work very good in linux. But a lot of cards work (with ndiswrapper if necessary).

For the routing, see the wiki.

Thank you for the wiki-reference, I didn't quite know what to search for. Sounds simple and I'm going to give it a try within the next days.

Well, I tried to set it up to day, realizing that it is probably not as easy as it appears to be.

I did everything according to the wiki but from the laptop I can access either the internet OR the other computer, but not both at the same time. It seems to depend on which network profile I activate first.

If I first activate and configure the ethernet card, I can acces the other computer (I tried ping and ssh), but if I then start the wlan profile I cannot access the internet on the laptop. If I start the internet profile first and then configure the ethernet card, I cannot ping the media pc anymore.

I'm not sure what could be wrong, as I just did everything according to the wiki entry. Ideas?

Ok, I've got it working after configuring it with different IPs than before. I'm still not quite sure what was wrong as there should have been no ip-collisions anyway. However, with a couple of personal adjustments, the wiki-configuartion works just fine.
