GA-K8NF-9 rev.1 and Gigabit LAN problems
First of all, hi to everyone! :-)
Yesterday I've bought the router Netgear DGN3500 with gigalan, but LAN on motherboard works olny until 100Mb/s. I Cannot in any way to make it run at 1 Gb/s. In the advanced settings of the ethernet adapter the selectrd speed is on "autonegotiation" but the speed of 1000 Mb/s doesn't appear among the options. Cable is a Cat.5 cable, compatible with Gigalan, included in the package of the router. Drivers (SO in my PC is Windows 7 32 bit) are the last release available for nForce4 which works with Vista/Win7 32 bit (Driver Ethernet v67.89 "WHQL"). LAN drivers 6.66 available on GIGABYTE web site are for WinXp and doesn't work at all with Windows 7. Do you have a suggestion for me before I buy a PCI ethernet card? Many thanks in avance for your answers. ;-) |

Many thanks in avance for your answers. ;-) The RJ-45 has 8 pins on the connector. When operating at 10/100BT Ethernet rates, only four of the pins are used (pins 1,2,3,6). When operating at 1000BT rate, all eight pins are used. Check that the cable being used, has a total of 8 wires. A very old cable may only have four wires and be thinner looking. If the cable has four wires, the autonegotiation process will be limited to 10/100BT rates. Also, check the Ethernet connector for contamination. On my P4 based motherboard from Asus, the Ethernet connector was dirty from the factory. By plugging and unplugging the Ethernet cable five times, that scraped the debris off the gold plated contacts in the RJ-45 connector housing. And then, my Ethernet worked at 1000BT. The motherboards are washed after soldering them, and sometimes residue from the wash water, contaminates the connectors. ******* When I needed a gigabit Ethernet card, I bought a PCI card with a RealTek RTL8169SC on it. I could get about 70MB/sec from it, in my first tests. Some of my other PCs, with GbE interfaces, can run 117MB/sec usable transfer rate, in similar tests (out of the cable transfer rate maximum of 125MB/sec). After a lot more experiments, I determined the card needs a powerful processor, to operate at full rate. If the motherboard had a 4GHz Core2 processor, it could probably reach 117MB/sec like the other Ethernet interfaces. When I checked, it generated four times as many interrupt requests, as the other Ethernet chips I tested. So if you shop for a PCI Ethernet card, I would not recommend one based on RTL8169SC. There are probably some cards with Intel Ethernet chips on them, or even a Marvell Ethernet chip would work better than that. HTH, Paul |

As I wrote in the previous message, the cable is provided by Netgear for that router, and I'm sure that it does support gigabit because a lot of people hadn't any problem with it. Also, check the Ethernet connector for contamination. Many thanks for the suggestion, but if I will decide to open the PC I will take this opportunity to put inside the new ethernet card... ;-) So if you shop for a PCI Ethernet card, I would not recommend one based on RTL8169SC. There are probably some cards with Intel Ethernet chips on them, or even a Marvell Ethernet chip would work better than that. I thought I would buy the D-LINK DGE-528T but I've just discovery that the chipset of this card is the RTL8169SC. So I will check for another adapter... |

GA-K8NF-9 rev.1 and Gigabit LAN problems
As they suggested in the nVidia forum, I've disinstalled and deleting
the nVidia driver form the system. Then I've detected hardware changes, so that the default driver of Windows was installed, and "et voilat", now the gigalan works. ;-) |
