* Degradation on b43 14e4:4315 ? @ 2011-06-16 8:16 Oncaphillis 2011-06-16 9:22 ` Rafał Miłecki 0 siblings, 1 reply; 5+ messages in thread From: Oncaphillis @ 2011-06-16 8:16 UTC (permalink / raw) To: b43-dev Hi, I'm using my b43 14e4:4315 on my acer notebook for quite a while now. I've started to use a wireless git-kernel and helped a bit in debugging initial problems with this device. Since the early Fedora 14 it seemed to work out of the box, but now when Fedora 14 moved to 2.6.35.12+ kernels I loose connections on heavy transfer. It doesn't seem to be related to DMA since for testing purposes I've disabled DMA. Where there developments during the 2.6.35.x developments which could explain such behaviour ?

Do you mean 2.6.35 was working fine and 2.6.35.12 already contains regression? Were you using clean 2.6.35 earlier with success?

Were you using clean 2.6.35 earlier with success? I started up with the wireless git-repo and somewhere since the early Fedora 14 it worked for me with the fedora standard kernel. Throughput could have been better, but I never got such disconnections ever since.

And it's wpa_supplicant that does it all wrong ? Please, try using DMA and provide us dmesg | grep b43 after seeing problems. I believe DMA has more advanced debugging implemented. >>> Where there developments during the 2.6.35.x developments which could >>> explain such behaviour ? >> >> Do you mean 2.6.35 was working fine and 2.6.35.12 already contains >> regression?

Throughput could > have been better, but I never got such disconnections ever since. Actually I > don't know if Fedora 14 started up with kernel 2.6.35 or even earlier. http://distrowatch.com/table.php?distribution=fedora says kernel 2.6.35.6 is default in Fedora. I didn't check for kernel history log yet, but I don't believe anything could change between 2.6.35.6 and 2.6.35.12 that is important for b43. After testing "DMA" and providing dmesg | grep b43, I'd like you to try switching back to older firmware. How to install older firmware: 1) Move newer firmware to other dir: mv /lib/firmware/b43 /lib/firmware/b43-478.104 2) Download older firmware and install it: wget http://mirror2.openwrt.org/sources/broadcom-wl-4.150.10.5.tar.bz2 tar xjf broadcom-wl-4.150.10.5.tar.bz2 sudo b43-fwcutter -w /lib/firmware broadcom-wl-4.150.10.5/driver/wl_apsta_mimo.o -- Rafa? ^ permalink raw reply [flat|nested] 5+ messages in thread
