On now 2 different access point i have begun to make a pattern of this - for many kernel releases if have had problems with my wifi performance. The more devices that wifi in the room, the worse it gets. However, i noticed, that it is not bad all the time, but sometimes the controller gets mad, and sets speed to 1(one)mb With the latest kernel i get the message in the titel in /var/log/messages every time the performance dips to 1mb Of course there are a lot reasons driver has to dynamically adjust its bit rate. Theoretically radio needs to measure how the media is. Bad traffic, contention and so forth...
(this is of course driving me crazy, and i plug a lan cable - if i am "alone in the room there is no problem) (i have of course tried to turn off everything, and the worst enemy of my wifi card seems to be the PC of my wife - which also has an Intel wifi. - Funny enough if she is booted under windows, then she does not have a poblem. If we are both linux (she is Opensuse 12.2)) we both have problems. Hmm..it is worth thinking. And it is obviously Linux has worse performance. But compare Linux with Windows is unfair. :)

I set the prio as a guess, since i have no customer case
And one more question, what do you do by the WLAN ? Download huge files ? Or just serf internet ? I would like to take your use case to observe the performance issue. :) -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Here some comments to your questions. Since i have a lousy ADSL performance, i am not used to filetransfers youtube etc (well i have free.fr in france, and they are not at good terms with google, so youtube is hosed anyway :-) So i normally see this error a lot when just browsing or reading mails, but it is for sure most present, in the evening, when all my neighbors are firing up their PCs as well. To give you an idea about the traffic, i have about 25 access points in sight, and they all choose the same channels :-/ in the meantime i am now on: uname -a Linux linux.site 3.8.2-1-desktop #1 SMP

Really good to hear of the result you nave. The WLAN driver is always developing in every moment. So there is no solid guarantee which version is working perfectly stable. Always try the latest kernel or compat-driver is suggested to verify the issue. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

a pragmatic Question - What is the mechanism to adopt compat-drivers in OpenSuSE - to better understand when to expect to see "my" problem resolved in the code on the opensuse repo's?
I am not quite sure how Open SUSE apply the compat-driver (compat-wireless) to the distro. Like what I say, the WLAN driver has been developing, each kernel would have lot patches, even though the mac80211 anc cfg80211 is still developing. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
