I have similar problem with MacBookPro8,1: firmware version 666.2 (2011-02-23 01:15:07) BCM4331 802.11a/b/g/n [14e4:4331] (rev 02)
There is a huge packet loss periodically that could be fixed by reloading b43 module: ifconfig wlan0 down; rmmod b43 ; modprobe b43 The problem could be repeated with: linux-image-3.5.0-18-generic linux-image-3.7.0-030700rc4-generic_3.7.0-030700rc4 I have tried to rollback to 3.2 kernel: linux-image-3.2.34-030234_3.2.34-030234.201211161335, but the problem persist, but at least with smaller probability. Steps to reproduce: 1) create a network load, like view video on youtube 2) browse normal web pages. Without downloading files or online video the probability to have high packet loss is low for me. The problem could be reproduced with different wifi access points: DDWRT on Dlink Dir-615 (G-only), ASUS RT-N12 with a stock firmware (N) TP-LINK TL-WR841ND (N) I think the same problem described here: http://permalink.gmane.org/gmane.linux.drivers.bcm54xx.devel/13499 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1058090 Title: [Macbook Pro 10,1] Extremely high packet loss with BCM4331 wireless To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1058090/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
