Comment (by Olivier Mehani <[EMAIL PROTECTED]>):
Additionally, the device seems to "flicker": only running iwconfig at a
few seconds interval, not doing anything else, the ath device disappear
and reappears, or is stated not to have any wireless extension:
Below is the output of 4 {{{iwconfig}}} commands run with a (manual)
period of a few seconds.
Not here at all:
{{{
[EMAIL PROTECTED]:~# iwconfig
lo no wireless extensions.
eth0 no wireless extensions.
ip6tnl0 no wireless extensions.
wifi0 no wireless extensions.
}}}
Present:
{{{

eth0 no wireless extensions.
ip6tnl0 no wireless extensions.
wifi0 no wireless extensions.
