Re: [Madwifi-users] Problem associating to AP with Orinoco 8482

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 454-5900

Hi John,
glad I'm not the only person seeing something like this.  I haven't taken=
=20
the time to investigate, so I haven't said anything.  I have the Orinoco=20
a/b/g silver card, which gets the same frame errors when talking with a=20
Cisco 802.11b (sorry, don't remember model), a Linksys wap54g, and any=20
other AP it's attached...

I rebuild from CVS once or twice a month, and have been noticing this for=
=20
the last 2 months (by now, I've just assumed I damaged the card). =20

Similar stuff though, but sometimes it will be fine, no errors; but=20
sometimes it'll start spasming, and lose it's association, then associate=
=20
but far more errors than good packets.

I haven't been able to (read taken the time to) what could be wrong...

Cheers,
Paul
