Ping 100% loss, 100% frame errors - help!

Post by J Alex Star » Sun, 13 Feb 2000 04:00:00



Hi,

I have searched around without success for a solution to the following
problem.  I have a network connection working on a laptop (3COM), and
tried using the same connection port on a desktop (NE2000 PCI,
Kingston KNE30BT).

I cannot get any data back at all.  All listed as frame errors.  No
network unreachable errors.

A simple ping results in all packets lost.

Any help would be greatly appreciated!
Thanks,
Alex Stark.

DETAILS.........

-----------------------------------------------------------------

Everything appeared fine with RedHat 6.0 from CD, detected painlessly,
etc.  No reason to doubt this side of things.

I once had a problem with MAC address filtering on this connection,
but hub has been set (probably).

MAC / hw address same as 3COM card on laptop.  (Same problems with
previous hw address, but ne2000-pci program was able to change it.)

Various configurations with route tried.  Laptop configuration matched
and failed.

NIC advertised as linux compat., and no reason to doubt from
diagnostics.

Link light on NIC shines with occasional flickers.  Acct light flashes
when pinging.

Twisted pair (10-BaseT/RJ45?) connection.  Cabling same as to laptop
dongle.

In following diagnostics, frame error rate is most significant.

You don't by any chance have a /dev/ttyS1 (Com2) or /dev/ttyS3 (Com4) port
on this machine, do you?  That might be interferring with irq 3.  I use a
Kingston card at work, although, it is Win95.  But I had a heck of a time
trying to disable Com2 on the motherboard because Windows kept finding it
even when disabled in CMOS until I disabled it in Windows and rebooted.
Try another irq if possible, irq 10 is commonly used by nics.  But it that
is used by your soundcard, you could try 5 or 7 (lp does not normally use
irq's in default polling mode).
