Thanks for your response!
Well, I'm running Ubuntu 7.04 64-Bit version
- "uname -a" gives: Linux laptopandi 2.6.20-16-generic #2 SMP Thu Jun 7

I have to add that I am sitting just in front of the wireless router.
The distance between router and notebook is at max half a meter. I find
it also interesting, that iwlist and iwconfig show different quality
percentages.
Kind regards,
