Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I have a desktop machine at home, running linux, and I have Verizon DSL. Verizon gave me their standard DSL modem, which includes a wireless antenae.
A couple weeks ago, a relative gave me two old laptops: a Dell and a Roadster with 64MB ram. The Dell still has windows, but I have installed Debian Etch on the Roadster. I did the netinstall through the wired connection. So far so good.
Then I went to buy a wireless card for my two laptops. I did my homework and made sure to get an atheros chipset so that I could use madwifi. When I scan for access points (APs), I see my network and my neighboor's. Now here is the funny part:
Using the Dell (windows laptop), I can DHCP into my modem without any trouble. Using the Roadster (Etch), I can only DHCP into my neighboor's modem. I can surf the web and everything, but obviously I don't want to be stealing his bandwidth. When I iwconfig to my network, DHCP refuses to connect...
Location: Somewhere inside 9.9 million sq. km. Canada
Distribution: Slackware 14.1, 14.2
It sounds like both you and your neighbor have not put any security in place. ie, you have not set an SSID, you are not using wep.
Routers come pre-configured to work out of the box, without any config. The problem is anyone can connect.
If I were you, go into your routers config for wireless and set a SSID and set up wep. Keep in mind you will have to set up the same options on windoze and linux laptops.
That should stop outside intruders, after all, if you can connect to his, the reverse is likely true also. BTW, if you like your neighbor, suggest to him to set up some security...
Once you set up the security, linux may not connect to anyone, until we figure out why not. Just a guess, but your neighbors router may respond to the DHCP request faster than your router, and on open networks, it will connect to the first one answering. Once you have set up some security, that issue should go away.
I can see my neighbors router also, but we both have some security in place.
Another thought, what channel is your wireless router set to? and are you trying to connect on the same channel on linux?
