Hello, I have the problem on a DELL D620 (0c:00.0 Network controller: Broadcom Corporation BCM94311MCG wlan mini-PCI (rev 01)). I don't know if it kernel related, I tried modprobe'ing with b43's parameters without success : modinfo b43 parm: pio:enable(1) / disable(0) PIO mode (int) parm: bad_frames_preempt:enable(1) / disable(0) Bad Frames Preemption (int) parm: fwpostfix:Postfix for the .fw files to load. (string) parm: hwpctl:Enable hardware-side power control (default off) (int) parm: nohwcrypt:Disable hardware encryption. (int)
When I'm relatively close to the AP (like <5 meters), it works well (can get 1MByte/Sec). But when I go far the AP (like >10 meters), speed decrease drastically (<40kbytes/Sec) and something like "disconnection" occurs: no packets are received from AP for 10 seconds and sometimes more... I tried modifying iwconfig parameters (txpower, rate, ...) nothing helps... -- [Hardy] B43 Performance very slow https://bugs.launchpad.net/bugs/201103 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
