Nokia and WPA2 PSK

Dear Nokia,

I really like your phones and I have been using them for about 10 years, but please understand that WPA2-PSK keys can be up to 64 hexdigits long, not 63.

Please fix this issue on the Nokia E51 phone and any other phones on which this might be the same.

Also, please, don't suggest that I should persuade all the admins that use 64 digits long keys to change them and change every client that already uses such a key, just to allow a phone to use the APs they admin.

P.S.: Could somebody confirm/inform that the same issue affects the Nokia E71?

Update: The bug was confirmed for E51, E65, E66, E71 devices. I sent a report to the support for Nokia about this.

After setting up wireless via WPA2-PSK with AES and realizing I really need the new firmware, I ended up using the latest wireless-2.6 kernel from branch 'everything'.

Now I am again browsing wireless-ly and I am wondering if the digital divide isn't already here:



Is there any reason why this discrimination is done? do they fear that they won't be able to sell the series?

wpa2-psk with aes on a broadcom wlan0 (2.6.24)

Update: I managed to find out why the wpa_action stuff was needed. Please ignore the lines written like this; they are there just for reference.

One more update: it seems that the firmware needs to be in sync. I ended up using the wireless-2.6 kernel from the everything branch.

I just managed to get my wlan from my laptop to work with WPA2-PSK with AES with the free Broadcom driver (now named b43, formerly bcm43xx).

0b:00.0 Network controller: Broadcom Corporation BCM94311MCG wlan mini-PCI (rev 01)

0b:00.0 0280: 14e4:4311 (rev 01)

In order to do this I needed linux 2.6.24-1 from unstable and the b43 driver.

bounty:/home/eddy# lsmod | grep b43
b43                   119976  0
rfkill                 12816  3 rfkill_input,b43

input_polldev           9872  1 b43
ssb                    39428  2 b43,b44

pcmcia_core            46500  2 b43,pcmcia
firmware_class         15232  2 b43,pcmcia

The final trick was to convince wpasupplicat to reload the config with:

bounty:/home/eddy# wpa_action wlan0 reload
wpa_action: reloading wpa_supplicant configuration file via HUP signal

This is the wpasupplicant.conf file that I used:

bounty:/home/eddy# cat /etc/wpa_supplicant/wpasupplicant.conf | grep -v '^\s*#' | sed 's/psk=.*/psk=aaabbb___ENCRIPTED_SEE_wpa_password___cccddd/'
ctrl_interface=/var/run/wpa_supplicant
ap_scan=1
network={
ssid="toblerone"
scan_ssid=1
proto=RSN
key_mgmt=WPA-PSK
pairwise=CCMP
group=CCMP
psk=aaabbb___ENCRIPTED_SEE_wpa_password___cccddd
}

and this is the relevant interfaces area:

auto wlan0
allow-hotplug wlan0
iface wlan0 inet dhcp
wpa-driver wext
wpa-conf /etc/wpa_supplicant/wpasupplicant.conf
wpa-ap-scan 2

This is what it looks like when is working:

bounty:/home/eddy# iwconfig wlan0

And here's the result of a scan (relevant section):

and here is proof it works:

Thanks to all people involved in b43 development and all the ones made this possible (Debian developers).

Update: You need the firmware blob, which can be extracted from a Windows driver with bcm43xx-fwcutter (now called b43-fwcutter); I already had it from my previous attempts to configure wlan with bcm43xx. I am not sure if I should use the new tool. You really need the firmware and driver to be in sync.

Update: it seems the b43 driver page (the entire linuxwireless.org site) went down sometime yesterday evening, since yesterday afternoon I was browsing through the site without any issues. (Note: I live in Europe, for reference)
