[Bug 402586] New: Ralink RT2500 close to unusuable with openSUSE 11.0
https://bugzilla.novell.com/show_bug.cgi?id=402586 Summary: Ralink RT2500 close to unusuable with openSUSE 11.0 Product: openSUSE 11.0 Version: Final Platform: Other OS/Version: Other Status: NEW Severity: Major Priority: P5 - None Component: Network AssignedTo: bnc-team-screening@forge.provo.novell.com ReportedBy: dieter.jurzitza@t-online.de QAContact: qa@suse.de Found By: --- Created an attachment (id=223618) --> (https://bugzilla.novell.com/attachment.cgi?id=223618) Output of iwconfig for a rt61 and a rt2500 residing in the same PC, attaching to the same access poinnt. I have 2 computers running 11.0 with Ralink RT2500 wireless cards here. One has a distance of about three meters to the access point (only air in between) the other one about 6 meters to the access point (a wooden door in between). Both worked ok with openSUSE 10.3. After installing openSUSE 11.0, the performance dropped down to about nothing. Card: Ralink rt2500 Module rt2500pci.ko Encryption: WPA-PSK The connection speed is about 1MBit/second (this is what iwconfig says). And the performance dropped to unbearable. A rt61pci works (after downloading the firmware from the internet) as expected: connection 54MBit. As the rt2500pci is part of the official kernel, it is hard to test more recent versions for me. The one shipped with 11.0 is inacceptable. The link-quality levels are inappropriate as changing the antennas does not show any influence on this. Obviously there is something wrong with either the module or other parts of the configuration. Please fix!

I can confirm that iwconfig <DEVICE> rate 11M makes things work acceptable. However, the command iwconfig <DEVICE> rate 54M does _not_ improve things. So, mileage might vary and the measures required to get this going might vary as well. Who would be interested in a "smooth" integration of the commands above might download the attached script and do a insserv setwlanspeed This is a plaster for now, however, I still hope that the folks from the rx200-development team will find and fix this bug so the plaster is not required any more. Thanks for looking into this - and again, let me know which logfiles you need from yast - I always configure cards with yast if possible.

Instead, I still see statements that rt2500pci has rate problems. I'm sorry I cannot fix that - it requires deep knowledge of both the hardware and the driver, both of which I lack. In fact, it seems it's not easy even if you have the knowledge - if it was, the upstream developers would fix that long time ago already. I'm afraid I cannot do anything at the moment. The only advice I have is to buy a card that is fully supported in Linux by its manufacturer next time, which obviously doesn't help you. Closing as WONTFIX, hopefully the situation will improve during time. -- 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.

However, this time I come up at boot with a speed like 1M and can set it to 54M later on, giving me a decent speed and performance (10kByte/s download speed vs. 1.35 MByte/s download speed). The question arises now, how the default configuration is done and whether there is a missing initialization causing the speed of the devices to be so low initially. It is hard for me to tell whether this is a driver issue or a openSUSE issue, but maybe it can be tracked down somehow. The phyiscal distance between card and AP is roughly 4m, no metal no door, no wall in between the antenna of the AP and the antenna of the card (i. e. practically no distance ...). This cannot be the root cause for the problem.

Assume you are logged in and call iwconfig wlan1 rate 54M several times (maybe once, maybe four times ...) I end up with a fast system (as I already wrote). Now, imagine you say iwconfig wlan1 rate 54M auto afterwards the speed of the interface will drop as time goes by, and, even worse, the signal strength that is announced through iwconfig does the same. Hence currently the only solution to get things going is to do a iwconfig wlan<WHATSOEVER> rate 54M and do that as often as neccessary to reach this speed. If you let the interface select the speed you're screwed. Thank you for looking into this, but I think I will post a comment regarding this issue in the developer's mailing list. Nobody can tell that 2.6.27 would be an old kernel ....

Ivo van Doorn is one of the main developers. So, there is hope in the future, but everyone using rt2xx today needs a patch somewhere forcing the card to a fixed rate! Doesn't actually help but rises knowledge :-((( Hi, <...snip...>
iwconfig wlan<INTERFACE> rate 54M auto
now, speed will remain up for a while, then starts to go down step by step until the initial poor and inacceptable condition is met again: 1MB/s and apparently no signal strength. Weird.
Known issue, the driver has to be forced to a fixed bitrate. Could you try 2.6.29-rc2? I made a fix in there which I am hoping is the answer to this problem (But I haven't heard any testresults about it yet).
P.S. I readily sent this email this monday, but apparently it ended up in a big black electronic hole :-)
Just like every other mail send to rt2400-devel over the last 4 months. :( The spam filter was overacting and was filtering all mail.

I'm afraid it can't be fixed for openSUSE 11.1 then. Let's hope that the mentioned fix really helps or, if not, that Ivo will manage to solve the problem soon enough to be present in 11.2. Unfortunately, even if the patch worked for you, it would be too risky to backport it to 11.1. Sorry that I cannot help more. Closing as UPSTREAM, as the upstream knows about the bug and tries to fix it. We'll hopefully get the fix from upstream for 11.2. -- 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.
