Emachine keep saying ethernet cable unplug

It may be because of the Ethernet pin or with the plug. I would say try use with a new ethernet cable and see it works

You can try by resetting your router but make sure to back up all of your settings and then reconfigure.

• Unplug the power cord and the USB cable or Ethernet cable coming from the modem.
• Wait two minutes and then plug the power cord back in which will reset the modem.
• Take the straight through Ethernet cable and run it from the LAN port on the back of the PLAYSTATION®3 into the ethernet port on the modem (you may need to unplug the Ethernet cable already in there. Also, make sure a USB cord is not connected to the modem as this will cause your PLAYSTATION®3 not go online).

Turn on the PLAYSTATION®3 to log into the PLAYSTATION®Network (you may need to log in manually if your settings are not set to automatically login). When you are done with your online activity with the PLAYSTATION®3, turn off the PLAYSTATION®3 (refer to the Quick Reference manual) and then follow these directions:

• Remove the Ethernet cord going from the ethernet port on the modem to the LAN port on the PLAYSTATION®3 out.
• Reset your modem as you did before my unplugging the power cord for two minutes and then replug the Ethernet cable/USB cord coming from the PC to gain internet access onto your PC. (Please note that this step can be skipped if you do not want to have internet access on your PC at this particular time or do not have a PC at all.)
• When you would like to log back onto the PLAYSTATION®Network please follow the steps beginning at the top.

The modem setup should appear like this:

From there, please follow these instructions (from SCEA):

1. Select "Network Settings" under "Settings" in the home menu, and then press the "X" button.
2. Select "Internet Connection Settings", and then press the "X" button. When a message stating that the Internet connection will be terminated is displayed, select "Yes", and then press the "X" button.
3. Select "Wired Connection", and then press the "X" button.
4. Select "Easy" or "Custom" and adjust settings as necessary. Follow the on-screen instructions to adjust the required settings.

Note: You should always choose Easy before going onto to adjusting the Custom settings. In most cases, the Easy settings will work and are set automatically so you won't have to search for information that could have been gathered automatically.

If the local area connection icon specifies as network cable unplugged, then the computer has not sensed the connection between the computer to the cable modem / DSL modem, please reseat the cable behind the cable / dsl modem to the computer. If the icon still shows unplugged, then change the network cable between the two.

If the issue still persists, please revert with more details lik the kind of internet connection used and the reason for reinstalling.

When switching from USB to Ethernet (Or opposite) you have to unplug it, then hook up the Ethernet cable and plug it back in.

Assuming you have dsl, make sure your pppoe info are typed in correctly, if you are still using dial up,the cable wont plug into the rj45 ethernet port,

This can be done pretty much any time. You want to end up with the modem connected to the router, and router to computer.

Well what setup do you have, single computer? Make sure your network adapter works, is the key..run cat 5 cable from computer to modem and modem to wall outlet. If possible try your network adapter on another computer.

1. Restart your router
2. Restart your computer
3. Check your ethernet cable. Try another one if possible
4. Try to connect to another port on your router

10. Your port on your PC is dead(Heat by lightening)
11. Your router is bad
