Q. I've managed to enter the wrong user name in my iPad Sky Go app, and can't find a way to correct it, even if I delete the app from both the iPad and iTunes, and download and install it afresh. What can I do?

A. Your iPad, like all connectable mobile devices, has a Universally UNique IDentifier (UUID). I suspect that Sky's systems detected your iPad's sixteen digit UUID when you first used the Sky Go app, and linked the erroneous username to your iPad. They'd do this because the Sky Go services, whilst free, are available only to their subscribers. You need to call their help line - with your subscription details to hand - and ask them to remove the link, allowing you to sign in with the correct username.

Q. Sky have given me a wireless connector to allow my Sky+ HD box to connect to my wireless router, however it doesn't work. Sky blame the BT Home Hub 3 router, BT says that it should work. Which is right?

A. Checking the specifications for both boxes, BT are right: the router and the Sky box should work together. Your problem may be as simple as the signal from the router not reaching the Sky box, or being too weak where the it is. Try connecting a mobile telephone, laptop or tablet to your wireless network and then go and stand next to the Sky box. If there is no signal, or a very weak one - say, one bar - then you need to move the two boxes closer together. If the signal looks strong enough, use WPS to try to make the two devices connect. (WPS is an industry standard.) Press the Wireless WPS button on the BT Home Hub, then within two minutes press the WPS button on the Sky connector. The two devices should negotiate a connection, though this may take several minutes. If that doesn't solve things, with the connector connected to the Sky box, use the Sky remote controller to access the settings page - look for a spanner at the top of the screen - and then select the Network screen. This should show you a list of nearby wireless networks. Select yours and enter the password using the remote.

Q. Is it possible to copy television programmes from my Sky+ box to my computer, or a portable hard disk?

A. If you are running out of space on your Sky box, or you want to store programmes over the long term, the recommended way of dealing with this is to copy programmes from the Sky box to DVD or VHS. The Sky manual tells you how to do this. Having said that, yes it is possible to copy programmes to a hard disk or computer because the Sky box's disk is a standard PC component, but opening up the box will invalidate the warranty provided by Sky. If you are technically minded, or know someone who is, open the box, take out the disk and fit it into a special case that you can buy at places like Maplin. (Search for "USB drive enclosure".) Then attach the drive to a computer and transfer the programmes. To make the transfer you will need to use free software like Copy+ - go to http://www.skycopyplus.co.uk/ to download it. N.B. You will be able to transfer and watch only free-to-air programmes: encrypted programmes from, for instance, film channels will not work.
