It seems that the wireless network was disabled by something external to Linux (although I'm still not sure what that could be). Wireless support is back on my laptop : to get this I rebooted and went to the BIOS, then restore default parameters. Somehow this seems to have solved the problem. At the moment, the list of possible networks does appear, but communication seems very slow. If this behaviour continues I'll open a specific bug.
