We told them the link status was constantly "no carrier" (FreeBSD) and "cable disconnected" (windows) when the card was connected directly to some specific equipment (no switch nor hub in between). We did not have the pb when using an other NIC (100Mbps or 1Gbps) instead of the realtek one, the status was ok. We finaly sent to realtek this specific equipment that is a satellite modem integrating a 10/100Mbps NIC. Realtek investigated and discovered it is was that device that was not generating a correct signaling. Realtek sent to us an updated windows driver and we do not have anymore the problem under windows. :-( Below is realtek's technical conclusions: -- Regarding the problem for MS-7065 Gigabit and Linkstar Viasat (include xpc 855tzp80d4 add intel lxt971alc A4 (PHY) compliant issue), After testing, this problem was the Link down power saving mode of Linkstar INTEL PHY didn˙t meet the standard spec. (No matter if it is under link down mode, TX needs to send signals to link partners, but it seems part of INTEL chip TX didn˙t send out signals, and only used RX for link partner detection. As for the INTEL PHY determination, it is not able to detect.) In this case, when we enable the link down power saving mode, the INTEL PHY can˙t recognize the signal of our LAN chip and failed to link. When we disable the link down power saving mode, it will work normally. We also tested Broadcom / INTEL NIC, both of them worked fine because the power down saving mode was disable in default settings or maybe it does not even support link down power saving mode. The setting of Marvell chip is the same, so it also failed to link. Please check with Linkstar or your customer to see if it is possible to adjust INTEL PHY setting and disable the LDPS mode to solve this problem, thank you. -- Best regards, Emmanuel -- On Mon, 2006-01-30 at 11:39 +0100, Julien Gabel wrote: > >> I filled one a year ago, for the very same problem (encountered for two > >> years now).
