A wifi-connected laptop as a home server May 29, 2008

As probably many people nowadays, I only have laptops at home. Actually one for me and one for my girlfriend (luckily babies don’t need laptops yet:) ). As we made the move to laptops a long time ago, you end with older – perfectly fine – laptops. Similarly, I stopped making holes in the walls a long time ago and went wireless.

Laptop and wifi do not sound like a winning server combination, but for me they are. Happily, nowadays wifi is as easy in Linux as in Windows or MacOsX. But do you really want you laptop to use a graphical semi-interactive process to get it’s – often random – IP address? What if the machine will run without an X server?

wpasupplicant and the old manual network configuration come to the rescue. I use this configuration for my graphical over-sized living room divx/mpeg/flac/ogg/mp3-player laptop connected to my tv and stereo and non graphical print server (an old trusty amd 350mhz cpu with 160 mb ram and 4 gb disk) in the home office (far from the living room where we often work).

EDIT May 27th 2008: FIXED how to make the changes permanent.
EDIT June 4th 2008: Don’t forget to install as well
linux-ubuntu-modules (in this case linux-ubuntu-modules-2.6.22-14-generic) when upgrading your kernel.
EDIT Oct 16th 2008: The restricted driver included in Ubuntu has been FIXED and the card works out of the box when enabling it through System-Administration-Hardware Drivers. Thanks, Ubuntu!

It’s probably a regression: on this laptop the broadcom wifi worked fine on the previous Ubuntu releases (although limited to 24mbit/s) and now I see the speed is stuck to an unacceptable 1mbit/s. I guess that’s the price you pay for hardware from companies that are not open source friendly. (more…)
