Check correct connections of WLAN antennas in NUC8i7HVK (Hades Canyon) after exchanging the WLAN M.2 card

[Polarspan]

Hi,

I changed built in WLAN card "AC8265" to a "AC9260".

Now I don't know if I inverted the two antennas.

How to check if i plugged in in the right order?

By the way another question: How to check if the antennas are connected properly in terms of good connection, is the NUC or WLAN card checking if one of the antennas is not connected right? How can I check this?

1. The antenna with white sleeve should be connected to the AUX marked connector. It serves both, WiFi 2.4GHz band and the BT.
2. The antenna with black cable should be connected to the MAIN marked connector. It serves 5GHz WiFi band.
3. See this video (from 4:32), to see the both cables connected. https://www.youtube.com/watch?v=-fiePyi6Xu0
4. Here you will find additional information: https://www.intel.com/content/www/us/en/support/articles/000031221/network-and-i-o/wireless-networki...
5. If one of the antennas (or both) are not connected (or the plug/receptacle was damaged), you will have bad WiFi/BT performance

Hi Lawksman, thanks for you very detailed answer! According your description I connected it well :-)

For 5.) how to "check" easily and proper? I don't have specific software which could measure the true "throughput"......

Is it enough to proof if

a.) the NUC connects wireless to Internet for WLAN functionality and

b.) the NUC is able to connect via BT to e.g. my iPhone or Flat-TV?

Thanks again,

Klaus.

Here's a couple of links to a couple of bluetooth programs, one has a bluetooth signal strength function

Hi Klaus

1. I'm not an expert in this field. You may measure the Internet speed with tools like this (and there are many others): https://www.speedtest.net/ . Check both bands.
2. About the BT, if it is working with your TV and phone I think it is OK. However I've never used a tool to measure the signal strength.
