loss of wireless after joyride-1496 update

[Ricardo Carrano]

Dan,

As you noted, "intermittent" is wireless nature.

The WPN824v2 is, to my best knowledge, a preN router. Have you updated its
firmware?

It would be extremely helpful if you post, at some point in the future (or
send me if you prefer),  information on your experiences with this router
(if possible, add firmware version). We are interested in collecting
compatibility info, particularly with APs that implement non standard
mechanisms.

Actually, there is a wiki page for this:
http://wiki.laptop.org/go/Wireless_Access_Point_Compatibility

Thank you!
