Hello Maarten, I'm sorry for the inconvenience that you have faced with your NUC.
In regards to the warranty replacement of your unit, it will be necessary to replace the whole NUC, since we don't have spare parts.

I recently bought Intel NUC box D54250WYKH1 and few accessories such as Intel Dual Band Wireless-AC 7260 802.11ac Wi-Fi Plus Bluetooth adapter from amazon.com. When trying to install my Intel Wireless card I was having trouble removing the plastic covers from the IPEX connectors. During the removal of the plastic connector the tiny gold "pigtail / ipex connector" from one of the WiFi wires in broke off from the cable. I enquired with local technician to solder but did not get much help. Many people on intel communities have experienced this problem and you have replied suggesting replacement of whole NUC. In fact person who made step by step installation video on youtube did break that connector exact same way. What should I do know? Any help would be greatly appreciated. I am not technical person but if I get correct replacement antenna and instructions I will try my best to install.
I live in Australia.
My NUC product details:
product code: BOXD54250WYKH1
PGDownunder, as I mentioned before it will be necessary to replace the whole device.
Just in case I erased the markings of the NUC for security reasons, since all this information is public.
