If you have an old Wii connected to watch Netflix, you will need to find an alternative as Netflix is ending support on January 31, 2019.

Netflix is already sending out emails to its customers with a relevant announcement, warning them that Nintendo will "suspend" Netflix and other streaming video services for the Wii after January 31, 2019. The termination will come in parallel with the closure of the Wii Shop channel, and essentially the console dating back to 2006 will be useless except for playing games offline.
Netflix doesn't offer any alternative, other than for users to purchase newer hardware. Specifically, it says: "We hope you'll soon enjoy an even better Netflix experience on a supported device.".
