  • Tips, Tricks And Warnings

    • When reconnecting your equipment, you should always do this in sequence. So power up your cable modem first and wait for the lights to come on before powering up your router.
    • It can take a couple of minutes for your modem to sync to the network. The same goes for your router so be sure to give them some time when you're waiting to test your connection.
