dropped packets and multiple wireless Lan entries in rfkill

[sportsdude81]

I am getting really long latency (like 400-500 ms) and packets are dropping left and right. I have a Broadcom wireless card so I had to install there proprietary drivers which were working fine until the most recent update I got in 12.04. Now I have to wireless entries in rfkill:

[~]
$ rfkill list
0: brcmwl-0: Wireless LAN
	Soft blocked: no
	Hard blocked: no
1: hci0: Bluetooth
	Soft blocked: no
	Hard blocked: no
2: hp-wifi: Wireless LAN
	Soft blocked: no
	Hard blocked: no
3: hp-bluetooth: Bluetooth
	Soft blocked: no
	Hard blocked: no

the first brcmwl-0 is the broadcom one from the driver. I don't know where this hp-wifi one came from.

Does anybody have any insight on this?

Thanks in advance

Seem to fix this by adding this to my /etc/modeprobe.d/blacklist.conf:

blacklist bcma
blacklist brcm80211
blacklist brcmsmac
blacklist ssb
blacklist b43

got that gem from this arch linux wiki https://wiki.archlinux.org/index.php/HP_Folio_13
