Thank you for your answers.
The driver, I use, is madwifi-old. In fact, I think that the background scan
is only implemented in the "madwifi-ng" version. But my problem is that I
cannot compile the last version of madwifi-ng with my 2.4.21 kernel. The
compiler tells that the structure struct_netdev is undefined. After
research, this structure is only defined in 2.6.x kernels. So, is there a
version a madwifi-ng with background scanning, that I can compile with my
2.4.21 kernel, or is there a page or site, or forum where I can search for
this information?

Thank you.

Renaud.
