If you're using a second hand or loaned device, it may be connecting automatically. In which case, follow the Not you or Changed Device? link on the Sky WiFi landing page to reset the device and register it to your account.
Or you can let us know the device MAC/WiFi address by emailing wifiuser@sky.uk and we'll make sure you can register it to your account.
If you can’t find the MAC/WiFi address then email us anyway and we’ll help you find it.
You should remove this from your account (see How do I add or remove devices? FAQ for information) because if this device is still linked to your account - even if you aren't in possession of it - you're responsible for any loss or damage caused by unauthorised use of, or attempts to access, the Wi-Fi Service.
A MAC address is a unique identifier which is permanently set on a network enabled device during manufacture to enable the relevant device to communicate and connect to networks, including Ethernet and Wi-Fi.
Upon registration to Sky WiFi, the MAC address of the device used to access the network is stored in your account so that when you return to a Sky WiFi Hotspot, the service automatically recognises and authenticates the device and allows you to connect to the Sky WiFi service.
You can register up to six devices to your account.
To manage this, go to http://service.thecloud.net and login with your registered email address and password.
Then select Settings>Manage Your Devices and you'll be able to add or remove any devices.
With Sky WiFi you can register up to six devices on your account.
Performing a factory reset of your device will not reset the MAC address on your device, so to ensure that subsequent users of a device which you no longer own cannot access the Sky WiFi service via that device and generate data records which will be linked to your account, you should remove the device from the list of devices that are linked to your account.
For more information on how to do this, open the FAQ titled How do I add or remove devices?
This tends to happen when the device has been registered by a previous owner/user.
Read the section above Why did my new device connect automatically without me needing to register? which explains how to reset the device.
