Description Miroslav Pragl 2012-01-30 13:01:31 UTC
Description of problem:
Broadcom WiFi driver included with kernel (brcmsmac/bcma) is broken. It is unable to accept long WPA/WPA2 key (some 45 characters including spaces etc). Broadcom's driver (wl.ko) works like charm.

Version-Release number of selected component (if applicable):
3.2.2-1.fc16.x86_64

How reproducible:
Easily

Steps to Reproduce:
1. use NetworkManager to connecto to my WLAN
2. enter WPA/WPA2 key
3. NetworkManager keeps asking forkey like it was entered incorrectly. 
  
Actual results:
No association/connection to WLAN 

Expected results:
Connection

Additional info:
If I pre-save the configuration and switch to wl.ko driver I get connected(NetworkManager) within few seconds. After switching back to kernel-supplied driver I cannot connect.Same behaviour in GNOME and KDE. It happens only with LOOONG WPA/WPA2 key - I can connect to networks with shorter key, public networks, enterprise networks

Meanwhile I tried "broadcom-wl/kmod-wl" package from rpmfusion and it works as well. So only the kernel supplied driver is broken.

Arend, this kernel is using compat-wireless-3.3-rc1...

Comment 3 Arend van Spriel 2012-01-30 17:09:57 UTC
brcmsmac has no notion of encryption whatsoever as it does not provide encryption offloading to mac80211. wl.ko is not a mac80211 driver.

Comment 4 Miroslav Pragl 2012-02-09 10:24:13 UTC
It sounds legit but doesn't help me at all.
How can you help you to help me? wl.ko uses lib80211 and lib80211_crypt_tkip

I guess you want to help me, right?

Exactly how long is the WPA/WPA2 key you are using?

Comment 6 Miroslav Pragl 2012-02-09 11:21:08 UTC
Sorry, should have been "How can  Ihelp you to help me". Freezeing here, both brain and hands are malfunctioning :)


It's 44 chars long passphrase, includes UPPER and lower case letters, spaces, numbers and common sentence interpunction such as comma (,) and dot (.)


TIA
