Still not working? Access your router's settings and turn off the router's firewall*.

Typically you can disable your router's firewall to allow all traffic through. To locate this setting, consult the owner's manual for your router. Below are locations for the most popular routers:

    • D-Link: Found by selecting "Advanced," then "Firewall."

    • Netgear: Found by selecting "WAN Setup," then "SPI Firewall."

    • Linksys: Found in the "Security" settings.

*While Nintendo provides this information for our consumers' use, it is up to each consumer to determine what security needs they have for their own networks, and to decide how best to configure their network settings to meet those needs.

Still not working? Power cycle your modem and router.

    • Unplug both the modem and the router from the power outlet.

    • Wait a couple of minutes and plug the modem back in.

    • Wait a couple of minutes for the modem to initialize, then plug in the router.

    • Try again to download the update.
