Thanks to Nokias generosity I now have N800 to test the built-in UPnP features. But the first disappointment came soon when I tried to connect it to my wireless network. First I thought it doesn't even support WPA2. After digging through all the configuration dialogues I found a checkbox saying "WPA2 only". First problem was solved, WPA means WPA and WPA2. The second problem was to enter my 64 character Hex-Key since the input box for the key only takes 63 characters. After looking into the specs I learned that this 63 charater limit is to show the difference between ASCII-key input and Hex-Key input. But the Nokia people missed to make Hex-Key input available as well. So I looked for the gconf file that stores the keys for automatic login. You will find them in the directory /etc/osso-af-init/gconf-dir/system/osso/connectivity/IAP with a single file for every network you have set up. Please make sure you find and change the right config files. If you change the wrong ones, your device might behave strange afterwards. Do this at your own risk!

In this file you'll find the key in two formats: the ASCII one and the calculated Hex one. Unfortunately the Hex one is stored byte by byte and so the given Hex key has to be converted into a decimal number byte by byte. I was too lazy to do that and wrote a little PHP script to run from the command line.

#!/usr/bin/php
<?php
if($argc < 2)
{
die("Gimme a key!\n");
}
if(strlen($argv[1]) != 64)
{
die("Not a valid Hex-Key!\n");
}

$hexkey = $argv[1];

$values = array();
for($i = 0; $i < 32; $i++)
{
$values[] = substr($hexkey, 2*$i, 2);
}
foreach($values as $value)
{
echo('        <li type="int" value="'.hexdec($value)."\">\n </li>\n");
}
?>


This takes the given Hex-Key, splits it into bytes, converts them into a decimal number and prints the needed gconf XML. This can be copied to replace the stuff written to the file by the configuration dialogue.

Now you can set up your network with any key, store the configuration and modify it afterwards using the script above. Of course you shouldn't change the key in the configuration dialogue since this would overwrite the config file and leave your Hex-Key invalid again.

Please remember that you're directly changing the configuration of your device without error checking of any nice dialog window. SO DOING THIS IS COMPLETELY AT YOUR OWN RISK!!!
