This seems to be more of a problem with the youview box or ethernet cable you are using.
Sorry to hear you're experiencing issues connecting to the internet. If you'd like to private message me your phone number or account number would be happy to see if I can help.
Hopefully the new hub will resolve any issue, but am happy to discuss any problems you have.
you are plugging it into a yellow ethernet port on the hub and NOT the red port on the hub
