Standing by (and watching the networking threads go by...).
I am quite convinced they need to change the syllabus at kindy. Rather than teaching read'n, 'rite'n and 'rithmetic it needs to be web surfing, networks and hardware fault tracing...
It is simple people (ok, its simple for me, but not everybody has had my experience, I grant you that
From the top:
1. control panel -> system -> hardware tab -> device manager
2. open network adaptors. You should see each piece of network hardware you system has (I am talking internal hardware here). As a minium you should see the Realtek Ethernet NIC. That is the std port out the back of the laptop. If you have wireless, Bluetooth, USB Ethernet adaptors or PCMCIA Ethernet cards installed they should also show up here. If the device is active it should be showing GREEN. If the device is disabled (like the BT module for example) it will have a RED X across it. If your device is not even there you have a driver missing. In this case you may have a YELLOW ? somewhere else in the hardware manager list.
3. Assuming we have a GREEN device listed in the hardware manager list, exit the hardware manager window and double click on "Network Connections"
I will assume we are doing a cable connection and not a wireless setup.
4. Look at entries under LAN or High-Speed Internet. Is there an entry in the 4th column "Device Name" that lists "Realtek..."?
5. If an entry exists for the Realtek hardware device check the 3rd column "Status".
6. If the status is disbled, double click on the name of the device (I called my link "officelan"). It will bring up a window showing the Connection. Check that the connection speed matches your external hardware (say 100.0 Mbps). If it doesn't then you have either an auto negotiation problem or your external hw does not support auto-neg.
7. Click on properties. In the new window click on the Advanced tab. Click on Link Speed/Duplex mode. This will show you the current setting and allow you to manually change the connection type if required. Close that window.
8. Click properties again (the previous properties window gets auto closed).
9. In the General tab window, scroll down to the entry labelled "Internet Protocol (TCP/IP)".
10. Either double click on it or click on "Properties".
11. For an internal network of a few computers I would recommend you use fixed IP addresses. The standard (RFC1918
) for internal network addresses (sometimes called Private Address Space) is either 10.x.x.x (class A), 172.16.x.x (class B) or 192.168.x.x (class C). If you stick to these any stray packets that leak out of your computer onto the Internet at large are not going to cause any harm. My recommendation is to use the 192.168.x.x network address range. So lets say you pick 192.168.0.1 for your Sager and 192.168.0.2 for your second PC.
12. Select "Use the following IP address" and enter your IP address. In the subnet mask you should have 255.255.255.0 (for a class C network anyway - I won't go into what class C means here). I also assume you have not been messing with the Advanced settings either (DNS should be clear btw).
13. Close that window.
14. On your other PC do the same thing. Roughly the same setup is present from Win98 onwards. Obviously your hw will show up differently but the procedure is the same.
15. Although not strictly required for XP, I would reboot all your systems. Win98 requires it.
16. For XP/NT systems, open a command line prompt (ie. a DOS window) and type: ipconfig /all
First check your hostname - you did set your hostname didn't you???
Next look for your Realtek adaptor. It should show its physical (Ethernet address (this is NOT your IP address). DHCP should be OFF and the IP address should match the IP address you entered in step 12. The subnet mask should be also as in step 12. Default Gateway should be clear. Close the DOS window.
17. For Win98 systems click start -> run and enter "winipcfg".
This will bring up a GUI. Select the hardware device from the drop down menu and then click "Details". Check the IP addres and subnet mask are as entered for the second PC.
18. If all is well go back to control panel -> network connections, select the realtek device and check the link. Status should be "Connected".
19. Open a DOS window again, and type: ping <IPaddress>
where <IPaddress> is the address of the other system. So if you selected 192.168.0.2 you would type: ping 192.168.0.2
This should return with stats on the link.
If you still don't get anything you may have to get a copy of Ethereal
to do some serious network debugging.
20. For those of you that don't have a network connection showing up in the "network connections" window click on "Network Setup Wizard" and follow the prompts. Ignore the New connection wizard - it will only drop you into the Setup wizard anyway.
Let me know how you get on.
For anyone reading this post if you have any other questions about networking just post away and I will see what I can do to provide some answers.
