I recently got a new Acer Aspire ES 14 with Windows 10. Then I installed Ubuntu 16.04 LTS and everything went smooth - but I can see my neighbors WiFi on Ch 11 2462 MHz but not my own WiFi on Ch13 2472 MHz which even has a much stronger signal using my smartphone WiFiAnalyzer app.

jnl@jnl-Aspire-ES1-433:~$ lspci -knn | grep Net -A3; rfkill list

I tried (without success): sudo apt-get update sudo apt-get install git git clone https://github.com/kvalo/ath10k-firmware.git sudo mkdir /lib/firmware/ath10k/QCA9377 sudo mkdir /lib/firmware/ath10k/QCA9377/hw1.0 cd ath10k-firmware/QCA9377/hw1.0 sudo cp * /lib/firmware/ath10k/QCA9377/hw1.0 cd /lib/firmware/ath10k/QCA9377/hw1.0 sudo mv firmware-5.bin_WLAN.TF.1.0-00267-1 firmware-5.bin

OK - I am not in the US, I am in Europe :-) Date and time says Copenhagen - that is correct

Aahh, now I see what you mean - I could potentially solve the problem by switching the wireless access point to Ch1
