Ethernet Cable Connected But No Internet Access (Troubleshooting Ethernet Connection)

Ok, so the thing is that even after so much advancement in making as much effort as possible to go wireless, it turns out that cable still works better. But that won’t stop your Ethernet cable connection from going haywire every now and then.

If even after connecting your Ethernet cable, you have no access to the internet, allow us to show you the best ways to sort this issue out.

Ethernet Cable Connected but No Internet Access

Let’s Go with the Basics First

  • Check, if the power’s out or something. See, if the cables are connected properly with everything they need to be connected with. Are the lights on the router/modem blinking? Try using the other port for ethernet. Everything cool? Ok, then.

So, now that the basic solutions are no help to us, let’s delve deeper and see if any of the following solutions are working. Hopefully, you won’t need to buy a new cable or call your ISP people or something. 

  • Check Ethernet Situation (Turn Off Your Wi-Fi)

Ok, know that this step is NOT going to help you in a direct way. It is only going to tell you where the problem lies. See, if you have both – Ethernet cable connected and Wi-Fi turned on. Your device will automatically give priority to the cabled one.

Turn Wi-Fi off and see if there is still connectivity showing. This will tell you whether there is a fault in the cable or in your connection. 

Then, we can take appropriate measures.

  • Try Restarting Your Computer (And Your Router)

Ok, so do this

  • Turn off the device first
  • Then, turn off the router and the modem, and remove them entirely away from the power source
  • Cool, now leave them be like that for a few minutes
  • Reconnect all of them back to the power source and turn them back on
  • See if you now have internet access
  • Broken Cables!

It seems pretty simple but hang on, let’s just try this – check if the cable is broken. Change the primary cable with another one, and see if that one is working. You might not have a spare one on hand, but if you do, then absolutely try that first.

Try having those special routers installed – those with special switches just for the purpose of checking on faulty cables.

  • Bad Router, Bad, Very Bad Router!

Ok, so here’s a very weird situation – some routers just disconnect the access to the internet to wired connections randomly Restart yours, and see if your internet is back. Consider buying a better router if this one doesn’t work.

  • Right-click on whatever network connection you are using (Ethernet or Wi-Fi) and select Properties

If Neither the Ethernet nor the Wi-Fi Gives You Internet Access!

Yep, that happens sometimes, let’s see what causes this and how to fix that in the easiest terms –

  • The most common reason could be a botched internet configuration. To fix it, you must have the router’s interface or its app and the ISP-provided username and password. Go to the Quick Router Setup (or something similar). Here you’ll be able to re-run the initial configuration wizard, using proper info. Once you finish the process, you may gain access to the internet.
  • If there is a problem inside your modem, then you can’t do much besides restarting the modem. If you think this needs more than that, contact your ISP for support.
  • Your machine could be added to the blocklist of your router. Don’t sweat upon it, it could happen for weird reasons. Just access the interface of the router, select the device that is blocked from the list and select Remove device from Blocklist
  • There is a Parental Control enabled! Access the router app, and then either disable the scheduled internet access or remove your device from the list.
