Thank you for joining the community.
Could you provide us the Intel® System Support Utility for Windows* report?
Please attach result in the tread.
What is the transfer speed if you try sending data from the NUC to a pc on your local connection?
The 40Mbps is your downstream speed?
Thank you for your response.
Could you download the Intel® Wireless Technology-Based Driver on the following link?
Can you try to completely delete the Wi-Fi/Bluetooth® Driver following the steps on the following link?
Once the driver is removed; reinstall de drivers version previously downloaded.
Please let me know the outcome.
We noticed that you're unable to get the performance you hoped for in your Intel® NUC using the Intel® Dual Band Wireless-AC 8260. I've moved your thread over to our Wireless Networking Support Community in order to better assist you.
First, let's make sure that you're using the latest drivers. Always install your Bluetooth® driver first, followed by your Wireless driver.
BT: Intel® Wireless Bluetooth® for Windows® 10 Version 20.30.0
WiFi: Intel® PROSet/Wireless Software and Drivers for Windows® 10 Version: 20.30.1
Once you've updated to this latest release, please run the following command:
1. Right click your start menu icon and select Command Prompt (Admin) from the list.
2. Enter: netsh wlan show interface
3. Using the Snipping Tool, take a screenshot of the result and attach it to your reply.
We would also like to know the brand and model of your wireless router or access point.
thanks again for getting back to me. I installed the updated driver and rebooted the NUC. but still, the download is very slow.
2.Mbps download and 7 Mbps upload
Would it make a difference the NUC is on its side to increase the range?
C:\Users\nuc>netsh wlan show interface
There is 1 interface on the system:

Thank you for this output.
This does not seem to be a range or reception issue, since your signal is already at 99%.
There's one more piece of the puzzle I would like to look into before providing suggestions.
- What is the brand and model of your wireless router or access point?
Based only on the output provided above, this seems to be an configuration issue with your wireless router.
The Intel® Dual Band Wireless-AC 8260 uses a 2x2 antenna configuration.
- When connecting to a Wireless-AC (802.11ac) capable wireless router, your receive/transmit rate should be 867 Mbps.
- If connecting to a Wireless-N (802.11n), you should see a receive/transmit rate of 433 Mbps.
At this time, we can see you're connecting to a Wireless-N network at 72 Mbps. This is a transmit rate expected for 1x1 legacy adapters, but may also be found if your router has a 1x1 antenna configuration and uses a 20 MHz channel width.
If the issue is your router, the low download speed could be caused by many factors, the most common being user congestion (too many devices connected to a legacy network).
