Ok. I don't know what I did wrong last time but now it works. The funny
part is that for the last week I have ifdown/ifup eth1 each times
manually.
I did some digging concerning making things smarter starting from
Jean Tourrilhes pages [1].
I believe what I am looking for is a script around 'iwlist eth1 scan'.
Apparently the airport driver doesn't support that.
I have also read [2] concerning the Airport driver that:
"The second version of the driver was also done by Benjamin
Herrenschmidt and is just a wrapper on top of the driver of David Gibson
(see section 3), and was integrated in version 0.05 (kernel 2.4.5). This
is a much cleaner solution, because both driver share the same source,
so the feature set is identical and all improvements and bug fixes of
the Orinoco driver are automatically in the Airport driver and
vice-versa."
I found a patch [3] to add the scan feature to the Orinoco driver version 11b (which seems to
be the one in 2.4.20ben8).
Is there a chance that it will add the scan feature to the airport
driver?
