[SOLVED]Wireless problem broadcom bcm4312 [14e4:4315]

I'm having a problem with my wireless. I have Broadcom Corporation BCM4312 802.11b/g LP-PHY [14e4:4315] and if I use STA driver I got kernel panic, I tried with activating PIO mod on the regular B43 driver and I have internet but with very slow speed never more than 128kbps. One friend of mine use ubuntu and he instaled some b43-lpphy or something like that and he have good connection. Is there any fix for this?

b43 should work for that chip.  You installed b43-fwcutter, right?

You could also try wl - which I generally wouldn't advise, but I've seen it work well with that chip.

Dou you have b43-firmware from AUR installed? It's the simplest way of Broadcom firmware in Arch.

Yes I installed b43-fwcutter and b43-firmware also, but still nothing.
I was using wl before but few weeks ago it start to show me kernel panic on every 5-10 minutes, and now I\m searching for a solution.

I get kernel panics with BCM43228 and kernel 3.8.*. Unfortunately b43 doesn't work with the card
so I have to stick to 3.7 kernel which gets more and more troubling. I'm waiting for wl driver update
because nothing else seems to work for for me.
Have you seen user notes at Arch wiki? This one:

I had to install it (wl) in the initramfs image, along with lib80211 and lib80211_crypt_tkip to avoid a recurring kernel panic.

or this:

The kernel panic can also be solved by blacklisting the brcmsmac, b43 and wl drivers. In rc.local you can modprobe wl without problems.

The second advice works in my case as long as machine is not suspended so not very useful for laptop.

broadcom-wl works the best for me. b43 is too slow to connect on mine. Just install it and it does the job by creating the blacklist rules and loading the appropriate modules.

keep your b43-firmware from AUR and don't upgrade your kernel past 3.7.9.1 if need be downgrade your kernel. Up until kernel 3.8.6.1 b43 does not work (except for wep security only  - wpa security networks not detected), enable "IgnorePkg   =linux linux-headers" in pacman.conf

have not tried kernel 3.8.7.1 yet

I have a macbook pro and had this same problem yesterday upon a system update to 3.8.*, and I fixed it by replacing my b43-firmware, which used to work fine, with b43-firmware-legacy package from the AUR... you may want to try this before trying downgrading the kernel,  you could always switch it back if you need to.... goodluck!
