I've got a really annoying problem with a Wireless card. For the first time ever I installed Fedora Core 12 Beta and my wireless card worked out of the box but it locks up the whole computer if i do big downloads. I'm getting lots of these messages from the kernel,
b43-phy0 ERROR: PHY transmission error
lspci -nn states i have this card
00:0b.0 Network controller : Broadcom Corporation BCM4306 802.11b/g Wireless LAN Controller [14e4:4320] (rev 03)
lsmod says i'm using the b43 driver.
I've tried downloading the drivers from here and replacing the /lib/firmware/b43 and legacy folders
and doing a modprobe -r b43, modprobe b43 then restarting the network to no avail I still get the transmission errors.
It worked fine with Fedora Core 11 and I don't really want to revert back because of other reasons.
I see lots of stuff on the net about this but I still haven't found an answer.
Thanks in advance for any help.
