What does this "system - error" mean?

Question

It goes something like this...

"There is an IP conflict with another PC on this network"

I have a wireless network with good security protection.
My firewall is on and its a good one. Norton Internet Security.
I live alone and this is the only PC in the place.
If I log off and then log on again it goes away. Sometimes it comes back sometimes it doesnt.

Thanks for the help.

Answer 1

Sounds to me that there is another computer on your network with the same IP address. Check your security settings to make sure no one is accessing your network unannounced.

Answer 2

It appears that someone nearby has accessed your Wi-Fi and is using it. This could be in a nearby apartment, house, or someone in a vehicle nearby.

Having a Firewall does not give you good Wi-Fi security. You need to have your Wi-Fi password protected and use WPA or WPA2 encryption.

This is generalized, but should help you in properly securing your Wi-Fi:

Most wireless routers are configured through your Internet browser. So you must connect your wireless router to a computer.

Type your router's IP address into your browser's address bar. You can find the IP address in your router's manual. You'll be prompted for a user name and password. These will also be listed in your manual.

You want to use WPA2 (Wi-Fi Protected Access) encryption to protect your network. You'll typically see this setting as WPA-PSK (pre-shared key). You'll be prompted to enter a password of eight to 63 characters--letters, numbers and symbols. The router will use the password to build an encryption key.

WPA2 is the latest and safest version of WPA. The only weak point of WPA2 is your password. So make it as strong as possible. Here is a tip that will help.

Your router may use WPA, the forerunner to WPA2. If so, be sure your password has at least 21 characters.

The earliest security standard is WEP (Wired Equivalent Privacy). Don't use that; it is easily broken. Check the router manufacturer's site for updates. If there aren't any, don't use the router to go online.

Now you must update your computers. Click Start>>Control Panel. Double-click Network Connections. Right-click Wireless Network Connection. Select Properties from the pop-up menu and select the Wireless Networks tab. You should see your network listed under "Preferred networks." Select it and click Properties. If it's not listed, click the Add button. In the box labeled "Network name (SSID)," enter your network's name.

Under Network Authentication, select WPA-PSK. Select AES under "Data encryption." Under "Network key," enter the same password you used for your router. You must enter it twice to confirm it. Make sure "The key is provided for me automatically" is not checked. Click OK>>OK.

Answer 3

Are you on a college campus? It sounds like the wireless router is messing up and issuing the same IP to different computers.

Next time, try clicking Start > Run > cmd
Enter.

Then type in ipconfig /release
then type in ipconfig /renew

and see if that fixes the problem without rebooting.

Answer 4

sounds like someone is using your wireless connection... thats about the only reason you would be seeing that error... unless you have a VOIP device (like Vonage or the one from the cable company) installed in your house... then that may be your problem.. I would check the security settings on your wireless network... if you need help contact the company the makes your router and ask them to make sure its setup securely

Answer 5

Umm just disconnect your network and plug it back in if that comes up there's probably someone trying to get on to your network not your computer.

Answer 6

just check your network connections
