Wireless Connection drops after a few moments

Question

Hello everbody!
Background: I have a cheap laptop with a windows only ACPI module, so I have to set acpi=off at all times anyway. I tried Ubuntu, which has the wireless problem too, but instead of repairing something bloated like Ubuntu, I now found my way to Arch to make it right from the beginning.
If the wireless problem gets solved, I want to go on installing the nvdia driver, maybe configure xmonad. (I want to try KDE4 for fun too though, eyecandy you know ) Simple working desktop without getting my laptop heated up like windows does.
The problem: I set up my wireless connection like the wiki says:
-The original SSID was "FRITZ!Box Fon WLAN 7270 Annex A" which I tried to escape with \ and using 'ssid'. This wouldn't work at all, if you have any explanation for that I'd love to know it. I changed the SSID to something without spaces and special characters and the connection would work. But it would be nice to change it back to the original.
-So it works now. Fine, I thought. But the connection drops after a few moments and I have to "killall wpa_supplicant dhcpcd" and start them again to make it work again. For a few moments only. So I went through the logfiles and found error messages which Google wouldn't help me solve on my own. Now I'm asking the Arch specialists here
Note: Using the partedmagic livecd, the wireless connection works out of the box and absolutely stable. I believe even a bit faster than under windows. So it has to work perfectly, I just don't know how to make it in Arch yet.

because the wiki says the driver is in the kernel, I also looked at the kernel log which has weird errors:

Thanks in advance to anyone helping me! I really really want to get Arch going. It's ideal for this laptop, no wasting of disk space, ressource friendly, the temperature doesn't go up as much with less cpu usage I guess..
I've written quite a bit, but hopefully this makes it easier for you to help me! I've included all I thought which could be useful.
Greetings from Germany,

Answer 1

The easiest solution might be to setup NetCfg somehow with your wifi card and access point.  Have you tried that?  Can you find your card's chipset on the wiki?(chances are that your particular chipset will need a firmware put into /lib/firmware.  Again that's found on the wiki on the NetCfg or Wifi page, I forget which sorry.)  Those are two places where I'd look for good information.
By the way, your rc.conf is way out of date.  You should look at updating it by using the recent rc.conf.pacnew file that you'll find in the /etc directory.
