For years, I had problems with the default route going away with a wi0
card. See, for example, http://mail-index.netbsd.org/netbsd-users/2003/12/17/0000.html
I now have a new laptop, with an ath0 wireless card, and I'm seeing the
same thing. It isn't a signal strength issue; I've seen it with the
laptop in the same room as the access point. I saw it 20 minutes ago;
wlanctl says there's a received signal strength of 53. Carrier didn't
drop, according to ifwatchd. I don't know how good 53 is on an
absolute scale, but with the AP about 1.5 meters away I see 53-64, so I
assume it's pretty good.
So -- does anyone have any idea what's going on?
