FATAL: Error inserting iwlagn (/lib/modules/2.6.39.4-11/kernel/drivers/net/wireless/iwlwifi/iwlagn.ko): Unknown symbol in module, or unknown parameter (see dmesg)

iwlagn: Unknown symbol ieee80211_get_tkip_key (err 0)

Any idea how to fix this?

Thanks

Hi,

I have not tried this on the B3, but I had some issues with it on a laptop.
Did you install the firmware? It is not on the B3 by default...

1. The module to load for 6205 Wifi-card is 'iwlwifi' (here the info from my Wheezy desktop):

Code: Select all

$ lsmod | grep iwl
iwlwifi               166761  0 
mac80211              192806  1 iwlwifi
cfg80211              137243  2 mac80211,iwlwifi
2. The necessary firmware file (kernel ≤ 3.2) is

Code: Select all

version 17.168.5.3	(iwlwifi-6000g2a-5.ucode)
It has to be placed in /lib/firmware.

One remark in case you want to set-up an access point:
This Intel-card works great in infrastucture mode. In AP-mode it is crippled and only allows channels 1 - 11 in the 2.4GHz band, nothing on 5GHz. Unfortunately Intel has placed the channel-table not in an EEPROM, but in an OTP-ROM. Thus it is possible to patch/overwrite the table to enable channels 12+13 and also 5GHz, and this survives a reboot, but on every power loss the patch is lost and the card reverts to the original state.
