Loss of i-service radio

X12 connected wired to BT hub. Has worked fine for couple of years but now internet connection is unavailable. I have tried re-entering IP address via auto-connect and manually and all the IP information is recognised in the Network Information but still no internet and no i-service. Receiva i-radio does not appear as an option in internet services. Any suggestions gratefully received - I have tried disconnecting and re-installing the network connection several times but problem remains? BT Hub working fine on other wired and wireless connections.
