[SOLVED] Home Networking Issue

Cleffer · 01-17-2008, 12:43 PM

God I hate networking, especially when I run into problems that don't make any darn sense to me, like this one.

I have a small network in my house. I have a central router and a hub. Here's what it looks like:

Router
1. Computer
2. Line to hub
3. Xbox

Hub
1. Computer
2. A "workstation" where I have one network line that I plug in the computer I am working on at the time.

The rest of the ports are open.

Everything was working FINE until yesterday. Suddenly, none of my workstation computers work. I currently have two computers there and between them have three functional network cards.

Here's what I've done and has failed.
- Tried "repairing the connection" option.
- Restarted the computer.
- Tried the line in all network cards in all computers, restarting the computers when I plugged the line in.
- Moved to a different port on the hub.
- Used network line on computer on hub port 1. It worked.
- Used network line from computer in hub port 1 on all the workstation computers and it did not work. (Plug both lines back in to their respective computers and everything is fine.)
- Tried to manually configure IP address and gateway without DNS name to access and ping local computers. It shows a 10MB connection (All are 10/100 cards) but get nothing on the web and no local ping responses either.
- Tried renew command.

More information:
- The IP address for the main workstation computer shows something I've never seen before. It's an outside address that is not local. All my computers usually have 192.168.15.xx addies for the router.
- The subnet it automatically assigned is 255.255.0.0, which is the wrong network class, obviously. My other computers 255.255.255.0
- All IP and DNS addresses are configured for automatic assignment in network connection properties.
- The network connection are assigned by DHCP.

I know I suck at networking. But I can hardly believe that I have 3 bad network cards between two computers... Something is going on here that I am missing or do not understand.

Thanks for your time and help.

Nevermind. I got it. I had to reboot the router and then the hub.

My router caught the sniffles. :)
