No internet at all works when ethernet is plugged in?

[Nihaal]

My laptop has been having internet issues lately. Wifi is working perfectly fine when I am close to the router, but the second that I plug in an ethernet cable, after a few seconds, I lose internet connection. This happens even if I am still connected to wifi; the ethernet cable stops any and all connection after about 10 seconds. This started happening seemingly randomly a few days ago, and ethernet has happened to work once or twice since then but every other time it doesn't. I've tried many things such as different ethernet cables but I can't seem to work things out. Help please?
This is only happens to my laptop. All other computers have ethernet working properly
All drivers are also up to date

Sounds like you may not have the router / modem / computer connect right. Make sure you have house cable line going into modem, then line from modem into the right port in the router, then a line from the router to the computer.

Try updating you ethernet controller driver from the support Page of your laptop manufacture.
