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 tried to look up for the information that looks relevant.
if there is a more elegant way to send it (maybe there is a way to put files in the forum), tell me.
Or if you prefer I'll send all the information' so I'll do.

looks like you have realtek wireless card just like me.
and I have the same problem.
also it differs depending from what router or what the signal strenght is.
it has never happened to me at home, where the signal strenght is very good (I have a Linksys WRT54G with Openwrt)
but I now at least one place with the same router but original firmware where it happens all the time, also the signal is weaker there.
haven't had the time to look closer to that problem, but I figured that it's probably a driver problem.
wireless support gets better with every kernel upgrade. I would suggest upgrading your kernel, this has fixed many of my connection issues. You can review alienbobs wiki for help with that. It also really improved my bittorrent quality as well.
well in the place where I have those problems they don't seem to bee happening with vista.
hate to reboot to vista just to get wireless, but when I need it, I don't have the time to look closer to the problem.
gonna check about the channels. Could it be possible that the windows driver solves such problems better?
You can rule out a channel conflict since it's working fine under Windows.
Just "for the record": random disconnections do seem to be a common problem. A month ago I tested five distros (Mandriva, Slack, Fedora, Gentoo, Ubuntu) on my laptop (Toshiba with Atheros AR5005G) and all five suffered from constant, random wifi disconnects. Lease time isn't the case here, DHCP is set to renew lease every twenty-four hours. Signal strength isn't the case either. wpa_supplicant never reported any errors, same for dmesg. I know at least two people who are having the same issue.
And yes, there is a way to use your Windows drivers - google ndiswrapper.
