Answer : cannot enable network

I have just returned to the site where network installation is ongoing,and have discovered that there is a nasty kink/bend in the cable leading into the modem from the Virgininlet in house,Virgin are sending a cable install team out to renew,if this works which I think will .i will be a happy bunny,and learned sometinh today. thank you, for your advice I did check what was said,but all appeared ok,
