  • 家园 Help: Home Network Problem

    Network connection problem:

    I have two computers: one laptop and one desktop. I installed the

    DSL modem from laptop. Laptop is connected to port 1 on router.

    Desktop is connected to port 2 on router. Port 2 is tested on laptop

    and works well. THe "Local Area Connection" icon on the system tray

    shows everything fine except that the Received is 0 packets.

    The problem is that desktop can only send packets out, but receive no

    single packet.

    There are four components installed in "Local Area Connection Properties"

    1. Client for Microsoft Networks

    2. QoS Packet Scheduler

    3. File and Printer Sharing ofr Microsoft Networks

    4. Internet Protocol (TCP/IP)

    The DNS is 192.168.1.1. I tried these two methods to assign IP for desktop.

    1. Dynamically assigned or 2. Static assigned.

    Both don't work.

    Desktop Configuration:

    OS: Win2000 Professional SP2 build 2195

    CPU: PII 400 MHz

    Ethernet Card: RealTek RTL8139(A)-based PCI Fast Ethernet Adapter

    ISP: Verizon DSL

    DSL modem and Router: Westell 327W

    DHCP is enabled in Desktop and laptop.

    Any opinion will be highly appreciated.

      家园 Finally fixed

      Thanks all your guys, wildpig, mecho, melon,电子狼, highway, 魔法胖子,for your good opinions.

      It seems the NIC picks the PCI slot. The mainboard has five PCI slots. The first slot is for video card, the second one is for CMOS backup, the third one is for sound card. At the beginning, the NIC is at fifth slot. Then I moved it to fourth slot, no luck, then I moved it to third slot, Bingo, it works. The last step is put sound card to fourth slot.

      Thanks you all for great help again.

      • 复 Finally fixed
        家园 glad you got it worked out

        I guess there is some conflict between the IRQ's assigned to those PCI slots... Oh well, as long as it works...

      家园 Try to ping the router, and postthe result here please

      If the laptop is working but desktop isn't, the most probable problem is DNS server, as you said.

      So first try to ping the router (or gateway, normally 192.168.0.1); If there's reply, try to ping 66.102.9.147(www.google.com) or 68.142.226.35(www.yahoo.com) , and if there's reply again, there's definitely something wrong with DNS.

      Run ipconfig/all under command line mode on the laptop and see what the DNS server is. Copy these into the desktop and try again. Make sure the default gateway, subnet mask are the same, and using different IPs on them.

      Good luck!

      家园 try turn off fireway if any first

      1. turn off firewall for both machine.

      2. choose obtain IP address automatically

      3. choose obtain DNS server address automatically

      4. run command ipconfig/all figure out the IP address for both machine and your gateway address

      5. try ping each other

      6. check router configuration

      usally in IE type your gateway IP address like:

      http://192.168.1.1/ set up the router.

      • 复 try turn off fireway if any first
        家园 Could try ipconfig/release, ipconfig/renew and ipconfig/flushdns

        first /release then /renew, finally /flushdns, if obtaining IP address automatically

        (you can ignore the /release step, but I'd prefer doing it)

        • 复 Could try ipconfig/release, ipconfig/renew and ipconfig/flushdns
          家园 ipconfig error

          First try ipconfig /release,

          passed.

          Second try ipconfig /renew,

          error "DHCP server unreachable"

          The DHCP is 192.168.1.1

          DNS server is 192.168.1.1

          Default gateway is 192.168.1.1

          Subnet mask is 255.255.255.0

          IP address is dynamically assigned on laptop.

          I have copied configuration from laptop to desktop, and change the IP address to 192.168.1.25. But doesn't work.

          • 复 ipconfig error
            家园 会不会是你Destop的端口没打开？

            用netstat -a 比较一下laptop 和 Destop的区别？就比较本机port的端口，特别是不是数字的项目。

            你说的“DHCP server unreachable”当我的linux没设好的时候看见过。Windows 下没碰到问题，不知道会不会是同样原因。

    • 复 Help: Home Network Problem
      家园 What's about Default Gateway?

      try ipconfig/all at your laptop computer first, then do the same thing at another machine. Compare two results and hope you can figure the problem out.

      家园 How about Your router? In network, that is first thing

        家园 Router works well

        Router is part of modem. There are four ports. I tested all of them. No problem is found.

        When I tried to open a webpage from IE, it seemed to give an DNS error. So I assume it can not found the DNS server.

        I have tried to change these values in Local Area Connection Properties, but no success.

        • 复 Router works well
          家园 How is your router configured?

          I think what 电子狼 meant to ask is how your router is configured, especially the DHCP server part.
