Classic Controller
The Classic Controller is an extra controller that can be connected to the Wii Remote by a wire. It more closely resembles the shape of a conventional game controller, and has more buttons than the Wii Remote and Nunchuk combined. It has seven face buttons, four should buttons, a d-pad and two analog sticks. The Classic Controller was mostly intended for use with the Virtual Console, as Nintendo 64 games required more buttons that the Wii Remote and Nunchuk could provide. However, its popularity meant that several newer releases allowed for Classic Controller compatibility. It was sold separately from the Wii console.

The SNES Classic Controller was given Platinum members of the Japanese Club Nintendo in 2007. The shape of the controller is the exact same as the original SNES controller, meaning that it lacks the two analog sticks, two extra shoulder buttons and HOME button that the standard Classic Controller has, but is still used by connecting it to the Wii Remote by wire. It was never available outside of Japanese Club Nintendo.

The Classic Controller Pro is an ergonomically improved version of the Classic Controller. It's largely the same controller with the same features, but has two grips and the shoulder buttons are behind each other in pairs, rather than arranged across the top of the controller in a row. These changed makes the controller very similar to Sony's various PlayStation controllers. This controller is still connected to the Wii Remote by wire. It was sold separately starting from 2009; in time for "Monster Hunter Tri"'s release.

Referred to as the "Classic Kumi Controller" in the manual, this model of Classic Controller comes with the Partner CTR set of Nintendo 3DS dev kits, manufactured by Intelligent Systems. This controller model very similar to the Classic Controller Pro, but has a ferrite core towards the end of its cable, likely to reduce electromagnetic noise from the cables around it. This controller comes in a unique black and white colour scheme, similar to the colour scheme of the Nintendo DSi "Panda" dev kit.
LAN Adapter
The LAN Adapter allows the Wii to use a wired LAN connection, providing a faster and more stable Internet connection. The LAN Adapter is connected to the USB port on the back of the console. This was sold separately in December 2006, a little after the Wii's release. Nintendo continue to sell it today, as it is also compatible with later consoles, the Wii U and Switch.
