Great guide with clear pictures!

Question: Does the Wii U operate correctly without WiFi and without Bluetooth modules? Of course, no connection can be established thru these modules when they were removed, but, does all the other stuff work correctly and you can play your games as usual?

Bert Zweistein -

I am thinking you wouldn't be able to use any controllers if you did so because of their reliance on the Bluetooth module, no? I am not sure if the Gamepad controller uses only 5GHz wifi only or Bluetooth too

So after wasting quite a bit of my life looking for these parts. Here are the part numbers that you should type into the good ole Google machine or Ebay if you are looking to purchase these parts.

GamePad module (5GHz) : 2878D-MIC-B2

WiFi module (2.4GHz) Part number is: 2878D-WIN-A2

Bluetooth module Part number is: 2878D-WIN-B2

Just some dude -

How in the world am I expected to get these 2 cables off of the bluetooth adapter? I do not want to break them off but I do not think they twist off either

Shawn Berry -

Great instructions! Can anyone recommend site to purchase? Cheers & Thanks! Paul

Paul Edwards -
