Wi-Fi connected but no internet access with Atheros in 16.04 on Acer Aspire E15
I am dual-booting 16.04 with Windows 10 on an Acer Aspire E15 E5-575G-76YK. The Wi-Fi worked fine (but on the slow side) after installation, but more recently it will lose the internet connection despite still being connected to the network. It started happening once every hour or two, but now it can hardly keep the internet connection for a couple minutes before it drops. The only way to regain internet access is to restart network-manager several times, and then it only lasts for minute or two before cutting out again.
The output of lspci -nnk | grep -iA2 net; dmesg | grep ath10k is:

And this isn't a duplicate question of [3] - I have the ath10k drivers installed. Plus, the wireless did work somewhat well at some point, and has degraded over the past week to where it is now.
For what it's worth, the wireless on this computer has never gotten faster than 5 Mb/s in either Windows or Ubuntu.
If it's helpful, output of iwconfig is:

I asked a similar question about a week ago. Idk but maybe this will helpRtl8723be WiFi incredibly weak
1I am having this problem as well, similar setup (dual boot Ubuntu 16.04 + Windows 10), with the QCA6174, but on a Blade laptop.
The suggested setup according to Killer Networking here is as follows:
wget
sudo dpkg -i linux-firmware*.deb
sudo modprobe -r ath10k_pci && sudo modprobe ath10k_pciI'm currently trying with this firmware to see if there is any improvement, no issues at the moment, but time will tell.
