You appear to be experiencing the classic symptoms for the issue described here:http://www.intel.com/support/motherboards/desktop/sb/CS-034326.htm. Please follow the instructions in that document.
The NUC Does have the thermal pad that's over the SSD. It also seems to run cooler than my older NUC. I'll try increasing the fan speed this evening, but I'm planning to use it as a HTPC/music streamer so not sure a louder fan is a good solution.
Also, the SSD seems to be running fine and I haven't had any boot issues.
OK, I put the fan on manual at 100% and still have the problem. Unless there is anything else to try, looks like I'm doing a return.
I purchased 20 D54250WYKs all with 6235AN WiFi cards. Every single one of them drops WiFi within a few minutes. On top of that I get BSODs, freezing and weird system issues. I take out the 6235AN and all these issues go away. I ended up buying a 5300 WiFi card and it works great. I no longer have the connection drops or other problems.
I am sure some combination of drivers, firmware and BIOS will resolve the problem.
It's 100% not heat related because it dies within minutes of moderate use.
Intel dropped the ball here in a big way.
Sylvia, it looks like there is some conflict with the D54250WYKs and the 6235AN. JMAN replied to my post and has the same issue with multiple units. He resolved it by getting a different WiFi adapter. It doesn't seem to be the overheating issue. If that is so, it should be easy to set up and confirm. This is one of the packages the Intel EEP store is selling, so there probably will be more with the issue.
JeffT, we know that there some network adapters with this kind of issues (connection drops) Intel� Wi-Fi Products — TechNote: Sporadic wireless disconnects caused by data reordering issue
I’m going to report this behavior to the engineers since this adapter is in the list of tested peripherals.
Are there any news about the fix for 6235? Mine still drops connection, even after installing 16.7.0 software (Windows 8 Pro), and it's unfortunately pretty useless without Wi-Fi connectivity
Hello Slava Kolbaev, I will have to inform you that we are still working on it.
I just bought a new NUC 54250 with the 6235an card. I am having identical problems and unfortunately, the NUC is useless to me as well without WIFI. Any hope here?
same problem here
Hi all, I have a the same problem with wifi card.
My configuration is as follows:
- Intel NUC D54250WYK
- Kingston SSD NOW 120 GB
- 2x 4GB DDR3 1600MHz (Kingston)
- Intel ® Centrino ® Wireless-N 2230
- MS Windows 8.1 x64
Random happens to me that my wifi adapter is disconnected from the wifi network and can not connect again. All of the available networks are visible, but can not connect. Most often it happened to me when I played such games through internet. To reconnect to an existing wifi network I had to restart the PC, but it does not always help. I have installed all updates and drivers, but the problem persists. Finally, I also found that after disconnecting from wifi network I stopped working and the front USB ports.
I too have the same problem with the n-6235 card. The NUC is the D54250WYKH variant. All the components are on the tested peripherals list. I have the latest drivers.
Please take one day vacation and read this thread:
The thread was started 13. 8. 2012 and has now 1066 posts. Result : no solution! It's the longest unsuccessful thread I ever read. Intel is not able to fix the windows driver, but linux drivers working well!!
For windows user, the only solution is to throw the 6235 adapter into the trash can and buy another !
I have the same set as you and so has my friend too. I have replaced the wifi-card with a new centrino 6235 card and had still connection problems. I got fed-up with Intel not being able to solve the problems with the centrino 6235 wifi card so I replaced it with a Broadcom BCM943228HMB. I haven't had any problems since. Since Intel is unable to solve this annoying problem just return the wifi card and by one that is working.
Shame on you Intel!
