Description Ivo Sarak 2002-10-05 09:47:40 EDT

User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.0.1) Gecko/20020830

Description of problem:
3Com 3c509C-TX-M will give heavy packet loss (over 50%).

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1. Install RedHat 8.0 with 3Com 3C905C-TX-M;
2. Ping some LAN hosts


Actual Results:  Ping will report heavy packet loss (every time over 50%).

Expected Results:  No packet loss.

Additional info:

I changed the card to another 3Com 3C905C-TX-M and the results were the same,
but as soon I changed the card to 3Com 3C905B-TX-M, there were no packet loss at
all.

Comment 1 Arjan van de Ven 2002-10-07 08:07:43 EDT
have you ever tried this with previous linux versions ?
Comment 2 Ivo Sarak 2002-10-07 14:41:06 EDT
I haven't ran Linux on this machine, but this type of card does run with earlier
versions of RedHat Linux.
Comment 3 Tomasz Kepczynski 2002-10-28 13:24:38 EST
  I may have the same problem. I've spent last week trying to
find out the reason for very poor network performance and as the
last resort I grabbed today 3c90x-102.tar.gz from 3com and compiled.
Well, it worked for me like a breeze.
  I don't have heavy packet loses on ping (unless I start pinginig
with -f options and large packet sizes) but I do have very bad nfs
and ftp performance.
  I use RH 7.3 with the latest i686 kernel (kernel-2.4.18-17.7.x).
Comment 4 Ivo Sarak 2002-10-31 06:28:13 EST
3C905CX-TX-M is working OK, too.
Comment 5 Bogdan Costescu 2002-11-24 09:04:34 EST
Use 3Com's DOS-based tool to check media and duplex EEPROM settings of the card. They should 
both be set to "Auto" or "NWAY". Different cards even of the same type may behave differently 
because of these default settings.

Thanks for the bug report. However, Red Hat no longer maintains this version of
the product. Please upgrade to the latest version and open a new bug if the problem
persists.

The Fedora Legacy project (http://fedoralegacy.org/) maintains some older releases, 
and if you believe this bug is interesting to them, please report the problem in
the bug tracker at: http://bugzilla.fedora.us/
