Your modem has a sticker with useful information, such as your Wi-Fi name and password, your modem serial number and MAC address. Our customer service may ask for some of these details if you contact us.
You can usually find this sticker on the bottom or back of your modem. The serial number is usually shown as S/N. The MAC address of your modem is usually shown as HFC MAC. You can also find your MAC address on My BASE under Your home network > Modem.
