Help & troubleshooting for network issues, including connecting your device to your home Wi-Fi network, connecting to public networks, troubleshooting wireless issues & ethernet connections, and optimizing streaming performance.
As for setting up your Wi-Fi, that's usually done in your router, not your ISP. If you've never logged into it, it is probably already broadcasting Wi-Fi, and the default SSID and passphrase may be printed on the device. If not, you can log in and check them or set them. There is a good chance that the default login credentials to your router are "admin" and "password" (seriously.)
