I just got a D54250WYK -haswell I5 with 8Gb Crucial Mem, Intel 240Gb 530SSD, Centrino 6235AN wifi.
I put on Win7 enterprise and have loaded all the latest drivers for the NUC.
My sypmtom: I connect with my wifi and everything seems well at first. Then after 2 to 5 minutes, I lose the connection and it doesn't see anything to connect to. If I do anything to access the wifi such as try to disable, it just hangs there. I have to reboot and then go through the same process.
What I have tried:
Made sure I had the latest drivers and the latest BIOS.
Swapped for another 6235AN from another working 1st gen NUC. No difference.
I tried swapping the SSD from the other NUC, but it has Linux Mint on it and didn't like the video. I haven't yet tried updating the Mint.
I took out 1 stick of memory. Same issue. swapped with the other stick of mem. Same issue.
I put the SSD with Windows in the older NUC, along with the 6235an I originally swapped. This NUC runs just fine, no problems.
I can connect to the wired Lan with no issue. I haven't tried the Bluetooth.
So the issue seems to stay with the NUC unless its some driver difference between the two chipsets.
Suggestions?
