Network name (SSID)

 Set to a single, unique name (case-sensitive)

The Wi-Fi network name, or SSID (service set identifier), is the name your network uses to advertise its presence to other devices. It's also the name that nearby users see on their device's list of available networks.

Use a name that's unique to your network, and make sure that all routers on your network use the same name for every band they support. For example, don't use common names or default names such as linksys, netgear, dlink, wireless, or 2wire, and don't give your 2.4GHz and 5GHz bands different names.

If you don't follow this guidance, devices might not connect reliably to your network, to all routers on your network, or to all available bands of your routers. And devices that join your network are more likely to encounter other networks that have the same name, and then automatically try to connect to them.

Try tapping ‘other’ then entering your network name and password. If you can’t connect, go to settings>general>reset and reset your network settings.

If this doesn’t resolve the issue, you’ll need to book an appointment for hardware service.
