#52 Unable to get full duplex mode
I know a similar bug has already been reported, but
since it hasn't still been solved I thought it could be
usefull to get informations about the same problem on
another config. I've got a rtl8139 chip based card. The
card is plugged to a 10 Mbit full duplex hub through a
category 5 rj-45 cable.
When I load the module I get this annoying message :
eth0: Setting half-duplex based on auto-negotiated
partner ability 0000.
and then the card is in half duplex mode. As a result
the transfers are very very slow between my two
computers, and the Hub (manufactured by Planet) is
signaling a huge amount of collisions.
To be sure the nic is ok I tested it under windows 2k,
and everything was ok, no collision anymore, and fast
transfers.
The dumps are given in attachment.
If you need more information, you can contact me at
chelmi@chelmi.eu.org or shellmi@netcourrier.com
I hope this will help traking the bug down
sincerely,
Sebastien Harnist.
