Had written to the group previously about this problem, then used
another system for awhile on my laptop instead of FreeBSD in order
to get some work done. Now am running FreeBSD again, version 4.4
& everything is working fine except am still getting dismal speeds on
my cable Internet connection. When I had IPv6 enabled in the kernel &
in rc.conf, I would get the message "DAD detected duplicate IPv6 address
fe80:0004::02e0:98ff:fe8a:a1fc: NS in/out=3D1/1 NA in =3D0". I had read =
where
someone else had similar problems & that's when I commented IPv6 out
in rc.conf, took it out of the kernel & recompiled it. The 1st time =
after reboot,
I got great speeds for awhile. Then later it was back to about ISDN =
rates &
often much lower. On Ted Mittelstaedt's advice from message back from
several months ago, I've ordered a 3com 3c589c nic, because he said
that's the 1st thing anyone would ask me, if I had the same the problem =
with
any other cards, but while I'm waiting on it, I'd still like to get to =
the bottom of
this if I could. Below are copies of the current ifconfig & dmesg output =
along
with pccard_ether & the kernel config info. Please advise if there's =
anything
else I can post to help.=20
The pcmcia nic info is:
LinkSys Fast Ethernet 10/100 PC Card - Model NP100
Thanks to all for any & all help.
