pcmcia nic problems with freebsd 4.3 stable

Posted on 2001-07-15
Last Modified: 2010-04-22
On my Toshiba PII 266 laptop with a Linksys 10/100 Fast
Ethernet NIC, can access Internet & email & local area
network including ssh/scp but my download speeds on the
Internet are really slow, considering I have a cable
connection.  Originally, when I installed freebsd on the
laptop, it had my Linksys 10/100 pccard running on ed1.
I was told that was wrong, so I went into the kernel
config & changed to ed0 under PCI Ethernet NICs and
recompiled the kernel.Since making the change to ed0,
all of the above ability to access is still the same.
Unfortunately, the bad speed is still the same too.
Below are portions of my dmesg output &  ifconfig ed0
ed0 at port 0x300-0x31f irq 3 slot 0 on pccard0
ed0: address 00:e0:98:8a:a1:fc, type Linksys (16 bit)
ed0: DAD detected duplicate IPv6 address
NS, 0 NA
ed0: DAD complete for fe80:000a::02e0:98ff:fe8a:a1fc - duplicate
ed0: manual intervention required
mtu 1500  inet6 fe80::2e0:98ff:fe8a:a1fc%ed0 prefixlen 64 duplicated
scopeid 0xa
 inet netmask 0xffffff00 broadcast
 ether 00:e0:98:8a:a1:fc
From the looks of it, it looks like 2 things on the
system are trying to use the same resources. All 3 of
my computers are going to a Netgear hub, on to a Linksys
router/firewall box, & then to the cable modem. Neither
the windows machine or the slackware linux box have any
Internet speed problems. Can someone help me decypher the
above messages & maybe point me in the right direction as
to what to read to solve this problem? The part about
manual intervention is a problem. I don't know what the
system wants me to about it, unless it's something I have
to change in the kernel config & recompile. Was wondering
if the duplex was wrong on the pccard, that is maybe only
running at half-duplex, but then I read in one of the
news groups that if you're running through a hub, that's
the way it has to be anyway. Also, I've been told to
"sh MAKEDEV ed0" but the system refuses to do it. And
then, on the other hand, I've read where that's one
device you don't make, that it's handled directly from
the kernel. So, any light shed on this will be greatly
appreciated. If any other info is needed, please advise
& I'll try to dig it up.

It seems like you have configured the same IPv6 address somwhere else ...

Please provide  ifconfig -a output if possible...

Regrading Simplex operation:
I had similar situation with 3com card.
The problem has been solved using proprietary
3com configuration utility and setting card to
autosense mode instead of hard configured for duplex mode.

Here's the output of ifconfig -a

faith0: flags=8000<MULTICAST> mtu 1500
gif0: flags=8010<POINTOPOINT,MULTICAST> mtu 1280
gif1: flags=8010<POINTOPOINT,MULTICAST> mtu 1280

gif3: flags=8010<POINTOPOINT,MULTICAST> mtu 1280

Looks like you already have configured ed1
using the same IPv4 and IPv6 addresses.
Try to look through you /etc/rc.conf
in order to ensure only one device using these addresses.

If you want it to be ed0 - ensure that only ed0 is configured in rc.conf.
