> 95% packets dropped with Atheros in FreeBSD 5.4

[Andrew L. Gould]

I'm having problems with an Atheros PCI card (D-Link G520) when running 
FreeBSD 5.4 i386:

1.  I've been testing the card with the computers placed within 4 feet 
of the wireless router.

2.  When I tested the card in a AMD64 socket 939 computer, it worked 
fine in Windows XP (rules out hardware issues).  When I boot to FreeBSD 
5.4 Release (i386 port, not amd64), executing ping results in over 95% 
packets lost.  The on-board, vge ethernet port works fine in either OS.

3.  When I use the card in a AMD Athlon XP computer running FreeBSD 5.4, 
executing ping results in over 95% packets lost.  I cvsup'd overnight 
and rebuilt the world and kernel this morning.  The results did not 
improve.  The on-board, realtek ethernet port works fine.

What should I do next to find the source of the problem?

Thanks,

Andrew Gould
