My Notebook reconnects to wireless network every 1-5 minutes.
It really hard so surf web, but it also impossible to use skype, watch youtube, listen internet radio, since every 5 minutes I get disconnected.
Here is part of kernel log:

Update: I tried sitting next to router (Linksys WRT54GL v1.1), and I had not this problems any more. (I usually work on other part of apartment which is 6-7 far away from router).
BUT, I must state that even when I was on my usually place, the signal was very good and I had no problems with wireless before. And I use Windows sometimes, and I also have no problems with wireless.
Since the signal is very good on both places and I had no problems when using Windows, I had maybe a clue what could cause these problems:
Around me there is ca. 16 Wireless networks, and 10 of them are near to router and other 6 near to my usually position. I haven't checked, but I guess that notebook usually does not see all of these 10 network, and router does not see all of this 6, and this is somehow related to the CSMA and possible bug in driver. I am NOT wireless expert, nor my clue could be right, but this was my first thought, since everything is working fine in windows.
