Wireless connected but not opening webpages. Ubuntu 16.04

[ahears]

Ok, it could be that the "certificate" for authentication on your machine has expired but lets just put a pin in that for now. (Your cert is at '/home/federico/ca-bundle_uam.pem'.) Lets try to look at the logs for error messages. First I would like to know the Kernel Version:

cat /etc/lsb-release; uname -a

Then lets look at the logs for anything error related to the wireless driver "ath"

dmesg | grep ath

I am looking mainly for errors in the log files. so hopefully there will be something useful here.
Now lets backup the drivers to your "Downloads" folder for safe keeping:

cp -r /lib/firmware/ath10k ~/Downloads/

Only if the 'cp' command completed successfully, continue to remove any modified drivers:

sudo rm -r /lib/firmware/ath10k

Now lets re-install the firmware: (please see the note*)

sudo apt-get install --reinstall linux-firmware

Now lets disable the Power management in the configuration for the Wifi device:

sudo sed -i 's/wifi.powersave = 3/wifi.powersave = 2/' /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf

This will find and replace "wifi.powersave = 3" with "wifi.powersave = 2" in the file '/etc/NetworkManager/conf.d/default-wifi-powersave-on.conf' effectively turning off power management in the config for the network adapter. This should keep it from dropping connections. After you post the output from these six commands, please reboot.


*NOTE: Posts number 25, 26, 27, 30, and 31 all have a serious typographical errors! When you were working through the steps "Jeff666" posted some info and commands in numerous posts for you to try which may have helped, but both of you failed to notice that your wireless adapter device name is "wlp7s0" not "wlp3s7". Oops! Syntax is important. It seems like months of wasted time from February to March!

It also looks like your problem was already solved in another post 'https://ubuntuforums.org/showthread.php?t=2317452' (Ubuntu 14.04 not 16.04) but for the exact same wireless adapter. Have you tried that? Here are the compiled and edited results from that post:

sudo apt-get install git
git clone https://github.com/kvalo/ath10k-firmware.git
sudo cp -r ath10k-firmware/QCA6174 /lib/firmware/ath10k/
sudo mv /lib/firmware/ath10k/QCA6174/hw2.1/firmware-5.bin_SW_RM.1.1.1-00157-QCARMSWPZ-1 /lib/firmware/ath10k/QCA6174/hw2.1/firmware-5.bin
sudo shutdown -H now

On the "up side" of things, your hardware seems to be ok, there aren't any network collisions, dropped packets, jumbo frames, or network jabber that would normally be caused by a misconfigured/defective network adapter when connected to a network.
