Greetings to all who are hashing it out in tech support today! I've tried a few Google searches and Intel support searches with different verbiage, yet I still have not found a conclusive answer. Anyone with knowledge on this please chime in.
I'm about to deploy 20 machines that use an ITX motherboard containing an Intel Dual-Band Wireless AC-3160 (Model 3160HMW) mini-PCIe card.
Everything is fine on the MAIN channel (full strength ~150Mbps) unfortunately (at least to me at the moment) the AUX channel is lifeless if you disconnect the antenna from the MAIN channel.
My original understanding is that they worked in tandem, using antenna diversity. According to the Technical Documentation of the AC-3160, Diversity is supported. However, I must be wrong somewhere. I'm met with a red X and no networks available when I only have an antenna plugged into AUX.
If it matters, I am using Windows Embedded Standard 7 x64 with the latest drivers available from Intel for the AC-3160. AsRock IMB-150 ITX Motherboard and a Crucial 128gb MSATA drive.
On most WiFi Adapters, Diversity is an option that can be enabled or disabled in Windows' Advanced Device Properties pane. This is not the case in my situation, again, with the latest drivers installed.
TL;DR: What is the purpose of the AUX channel on the AC-3160?
Thanks for your insight in advance.
