Mando.Coin - Welcome to TSF,
Let's verify that all the network cables and connections plugged in to the proper Ports. From the Modem, the network cable need to be plugged in to the Router's WAN or Internet Port. Your computer and Xbox needs to be wired to the LAN Ports of your router.
Power Cycle your devices if above is confirmed.
Also, try deleting all Wireless Profiles stored and then reconnect to your own SSID, make sure that you type in the correct network encryption.
Test your connection after and an update will be nice.
