Hello
i've installed Kali linux yesterday, i didn't have an active connection during installation so i could not download the required drivers (as far as i remmeber it was b43-fwcutter or something

the wireless connection is working, but after few minutes it stops (doesn't show as disconnection or anything but no page will open, youtube stops etc...) until i reset connection

i've installed b43 module and firmware-b43-lpphy-installer

still same problem, not sure if module isn't loaded or i have to black list something?

lspci shows:

Network controller: Broadcom Corporation BCM4312 802.11b/g LP-PHY (rev 01)

lspci -k shows:
Network controller: Broadcom Corporation BCM4312 802.11b/g LP-PHY (rev 01)
Subsystem: Dell Wireless 1397 WLAN Mini-Card
Kernel driver in use: b43-pci-bridge

any help is highly appreciated,
thanks
