Thanks woodchip, Both Ethernet and USB connected which may sound strange. Ethernet connection no longer works directly although can't see any reason why it should not. BT 'India' helpline talked me through various Ethernet checks which were based on switching cables around to prove cables not faulty and couldn't get it to work and then talked me through setting up USB connection. What's odd if I disconnect Ethernet then USB connection doesn't work. Think fault on Ethernet is internal in computer but nothing showing up in System Devices. Presumably I am losing connection speed through not having a working Ethernet connection. Any ideas please?
