Hi guys i am experimenting issues with b43 driver on my macbook pro running fedora 19
My wifi hardware is Broadcom Corporation BCM4331 802.11a/b/g/n (rev 02) Subsystem: Apple Inc. AirPort Extreme
I can associate any hotspot i want and the network is working good for some minutes. Then wireless card begins to discard packet and the network become unusable.
I did follow this link http://linuxwireless.org/en/users/Drivers/b43/#Fedora to get b43-fwcutter and i grabbed proprietary broadcom driver for newer kernel.
Unfortunately i have no log, since dmesg does not report something anormal but i can assure you the network does not work more than a few minutes.
Could you give me a hand to get my hardware working ? thanks you so much
