Computer help needed

**cycfan** · 11-15-2011, 10:25 AM

I had a new power supply put in my computer yesterday. My wife's computer is connected to the router with those things you plug into an electrical outlet. Since I got the new power supply installed, my wife's computer won't recognize the network and won't connect to the internet. If I turn off my computer, the wife's computer connects fine. As soon as I turn on my computer, my wife's internet connection is lost and it says "unidentified network". Any ideas what is going on?

Have you had issues connecting 2 computers at the same time before? I know when my wife has her work computer home and is using it, my computer gives me a message saying another computer is using the IP but I can still use my computer.

If you are having IP conflicts, there is something wrong with your DHCP on your router. You may want to turn it off and back on again. You can also in most cases go into the web interface and delete the entries for you machines under the DHCP lease...might be a bit complex if you arent tech savvy though. Start with a reboot of the router. You dont happen to have the two machines named the same do you?

No, everything worked fine for a couple of years until yesterday when I had the new power supply put in my computer. Actually, I have had 3 computers connected, my computer, my work laptop that sits about 6ft away and my wife's computer in an upstairs bedroom. I have tried things 4 times now. With my computer shut down, start my wife's computer and it connects to internet fine and works fine. Then I start my computer and every time it says "unrecognized network". Then I shut my computer off and the wife's works fine again. Also during all of this, my work laptop is unaffected.

I tried unplugging and resetting the router last night. I went to the network section from control panel and it showed the IP address and says "address type: assigned by DHCP". I don't know what the DHCP is.

Go to start>Run Type in cmd and hit enter. You should get a command prompt. In this prompt, type ipconfig and hit enter. Let me know what it says for IP.

It says:

How about on the conflicting machine?

This is why I love CF.

This is dumb, but the other computer uses Windows 7 and I'm not familiar with it. I don't know where to go to get the "run" command. The start menu brings up control panel, computer etc. but no "run" command.

You can type it into the search programs and files space when you click the start button. Works the same.

Click the windows circle at the bottom left. In the search box, type cmd, it should pop up as the first result in the list above.

Yeah 169.254.199.251 is not a good sign. Is this when its up and running with the other machine off? Or with both on?

One thing you can try is to run a repair on the network adapter. You can get to that by going back to the search box and typing Network Connections in it and hitting enter. It should display your adapters. Right click on the live adapter and choose Diagnose.

This is with both computers running. If I turn mine off, the other one works fine. This is only occurring when mine is on. I'll try to repair the network adapter.
