Over time one collects lots of WEP and WPA keys with mobile devices like nokia´s n800 or n810. Often you want to use these keys with other devices or need them after reinstalling the OS.

For maemo based devices like the n800 and the n810 it is quite easy to recover the previously stored wireless keys, since they are stored unencrypted in gconf. Just open an xterm and enter the following line:

gconftool-2 -R /system/osso/connectivity/IAP |egrep ‘(pass|name|wlan_wepkey)’

The output you get is a list containing all wireless keys and network names you stored on the device. Note that the output contains the key first and the network name is being displayed a line below the corresponding key.

Did you ever ask yourself how to make your internet tablet more powerful?

For a Linux based device like Nokias N810 this question is quite easy to answer.  You can easily increase overall performance and responsiveness by using a “better” kernel than the stock kernel on your internet tablet. A further advantage is that you can add features that are not available in the stock kernel. Below you will find instructions on how to build your own optimized preemptive kernel or how to install my prebuilt kernel.

In both cases the following features are covered:

1. preemtive kernel
2. high-speed sd-cards
3. screen rotation
4. more granular backlight sertting
5. easy-debian image
