Good Morning. The network wifi on my Mac Mini stopped working suddenly and began to interfere with the keyboard and bluetooth trackpad. You can not find any network and disconnect the trackpad or keyboard when connected. I've tried everything but to no avail. Any suggestion? All USB 3.0 devices were disconnected and performed a reset SMC.

This system uses a combo AirPort card which has both 802.11 WiFi and Bluetooth services. Review this IFIXIT guide: Mac Mini Late 2012 AirPort/Bluetooth Board Replacement. Jump down to Steps 20 through 23 as you can see this one part handles both. Most likely you have a bad board, I would start there.
The part you'll need is: AirPort Extreme/Bluetooth Card - Apple P/N 661-6040

It's the same board of the Mac Mini Mid 2011? I found the Late 2012 plate with Part Number 661 7030.
Which do you have the '11 or the '12 model? The parts are different. The Bluetooth antenna is located in a different locations between them.
Mac Mini (Late 2012), 2.5GHz Intel Core i5
My mistake ;-{
You are correct you need the 661-7030 part I must have clicked on the wrong link.
Thank you Dan.
