| 385818 | 2005-09-03 21:20:00 | I have a P4 3.2GHz system with a Gigabyte 81915P Duo Pro motherboard, which has dual Broadcom Gigabit network interfaces. I have connected my other PC to one of the interfaces, using a crossover patch cable. The other interface connects to a Billion 7100 router for connection to my broadband Internet account. I have set up the connections with fixed IP addresses (192.168.1.2 and 192.168.1.3) and my other PC's Gigabit interface as 192.168.1.1, and the router is configured to work with the fixed IP address of its connection. The problem I have is that if I have the LAN connection working to share files with my other PC, then the Internet connection stops working. :waughh: If I disable the second Ethernet interface (so that I no longer connect to the second PC), then the Internet connection works perfectly. Any assistance getting this sorted out would be much appreciated! Steve H |

| 385819 | 2005-09-03 22:00:00 | Have you flashed to the latest BIOS?? According to the latest BIOS as of 2/1/05 I think it is, it says support Broadcom 5789 onboard lan . I think this is for your mobo . Whatever this means . Maybe the original BIOS didnt support both interfaces?? . gigabyte . com . tw/Motherboard/Support/BIOS/BIOS_GA-8I915P%20Duo%20Pro . htm" target="_blank">www . gigabyte . com . tw If u havent got the latest BIOS update, make sure u have the Duo Pro, before u flash the BIOS . And NOT the Duo Pro A . They're 2 different mobos . |

| 385820 | 2005-09-04 02:27:00 | Don't bother with the BIOS . ;) The normal rule applies: you don't "flash a BIOS" unless you know the new version fixes a problem you have . "Whatever that means" is not a good reason . Connect the other PC to the router . That is more likely to work . Your PC is only a single host, so it can only "be" one IP address at any one time, even though it has two Ethernet interfaces . Linux allows multihosting, but that's a real multiuser system . |

| 385821 | 2005-09-04 02:32:00 | Well, if u didnt NOTICE, the update is for onboard LAN . So, it must have something to do with one of them . IF u BOTHERED reading IT . |

| 385822 | 2005-09-04 02:59:00 | I read it. "... it must have something to do with one of them ..." is still not a good reason for a BIOS change. I read the question, too. Both interfaces work. But Windows doesn't want to be two hosts. So the easiest way to make this work as desired will be to connect the PCs through the router. That's what routers do. Different processes will be able to work through a single interface. |

| 385824 | 2005-09-04 04:38:00 | Possibly hes trying to use a gigabit crossover and fast ethernet to router? | HadO (796) | ||
| 385825 | 2005-09-04 09:18:00 | If you're using WinXP, rightclick one of the network connections and select 'Bridge'. That will allow you to 'connect' the two interfaces and leave you with only one IP for the machine. You should then have seamless connectivity. :) | wuppo (41) | ||
| 385826 | 2005-09-04 09:48:00 | It seems more sensible that if you have a 4 port router and two computers, add each computer to the router via its own straight through cable. Flashing the BIOS to me is a last-resort thing (i.e. you do it as a last resort) |

| 385827 | 2005-09-04 09:49:00 | I've got something similar to what you are trying to achieve working already. I've not had much luck with the bridging method mentioned above but I have had resonable success with Internet Connection Sharing (sad but true). Heres what I did; For your NIC thats connected to your router, open its Properties window in Network Connections and go to the Advanced tab. Tick the box to enable ICS and select the NIC that you want to use to connect to the other PC in the "Home network connection:" box. That should set your second NIC as 192.168.0.1. On the other PC, set its NIC to run on DCHP (obtain an IP address automatically). This works for me - admittedly I'm doing it with different hardware (wireless) but ICS is an easy way to set up this kind of thing. Hope that helps. |
