Ethernet: Current Operation Rate

Hello we have problems with Current Operation Rate detection on our 3Com ethernet card.
(devID=9055, driver devn-el900.so) QNX6.3.0.
Although ethernet card is connected to LAN , Current Operation Rate is “Unknown”.
(second card 3Com on another computer detect 100mbit/half duplex).
Both cards detect some collisions.

When I tryed to set duplex=1 , speed=100 parametres to driver, computer did’t connect
to LAN.
What can cause these problems ?

Thanks
David

I have seen incompatibilities between certain ethernet adapters and ethernet switches, which could be causing your problem. Have you tried connecting to another hub/switch?

Yes, problems are with hitech switch EdgeIron. With some cheap switch everythink is OK.
Problem persist even ethernet card was changed.
How can be solved this problem when customer want use this switch. ?
