Ethernet connection not recognised

Hi,

I have Technicolor TG582n modem which I have have had since signing up with plusnet several years back. Just got new TV which requires connect via ethernet connection to router but when I connect TV says no internet connection plugged in and the ethernet light on router doesn't light.

Connected laptop ( running Windows 10) to router via cable again nothing and running diagnostic in Windows it says a cable is unplugged ( or similar).

I have tried two cables type cm24awg verified to e1a/t1a-568b if that means anything.

With both cables to TV or laptop the ethernet light on router does not light at all.

Any advice appreciated

Re: Ethernet connection not recognised

Try in order (until something works):

  1. Restart router
  2. Factory reset router
  3. Replace router

Make a note of any router settings you have changed from their default values before carrying out step 2.

You need to use ethernet cable, such as a CAT5 or the ethernet droplead that Plusnet sent you with your router.

Re: Ethernet connection not recognised

Thanks for your help. Did a reset as suggested and Ethernet now working only trouble is can't connect any devices to internet.
All router lights on and showing ' signal strength good' but when I try to connect get message 'connected no internet'. I have tried Laptop, tablet and phone. Have deleted plusnet from WiFi connections on devices and tried reconnecting but same message. Once again HELP!!

Have you tried a cable connection?

Yep. Wi Fi was fine until I did the reset and as I say it's showing good signal and Ethernet connection now working but now I can't get any devices to connect.

Re: Ethernet connection not recognised

I'm not sure if your router will autoconfigure after the factory reset?. You may need to reenter your username/password into it again to make the internet connection
