Setting Up Wireless Home Network on Linux System

I received email from Johns on setting up wireless home network.

I currently use Alcatel modem (Speed Touch 330) given to me from ISP and I simply can’t get to work with Gentoo Linux (2.6.9 Kernel). I decided to build a wireless home network, so I’m planning to buy a D-Link DSL-G604T wireless ADSL router.
My first question is: Is this hardware fully compatible with Linux or do I need to install any drivers as with the Alcatel modem?
I have notebook and wanted to connect it to the network through a wireless cardbus adapter. I want a card supported natively by a kernel modulem, something that could work straight out of the box. After some reading, I found that it should be a card with Prism 2/2.5/3 chipset, but I’m confused and don’t know how to find a manufacturer or vendor of a popular cheap card with that chipset. So my second is, can you suggest a good adaptor using Prism chipset?

The wireless router from D-Link will make the connection to your ISP over DSL circuit, so you will not need any PPPoE or PPPoA support on the Linux system.

You can connect straight into the router using Ethernet and DHCP against the router for an internal IP address. Essentially, everything will be offloaded on to the router, making you Linux system a plain old workstation, rather than a router.

As far as PCMCIA wireless adaptors are concerned, you can check out www.linux-wlan.org or www.prism54.org

You’ll find that Prism54 identifies devices supporting the 802.22g standard as well as 802.22b for faster connectivity. Prism2 and Prism54 cards are identified by Knoppix at boot time, and will enable you to access the internet easily without having to install a large number of supporting packages.
