As mentioned in a different thread, I finally got Ubuntu 15.10 installed on my E5 573G-71L9. At first, the wireless LAN was not working, but I managed to find and install the presumably correct drivers.
As wifi still didn't work, I also figured out that it was the Atheros card that needed a proper driver. I followed this method (I basically just copied-pasted all commands without understanding them completely): http://askubuntu.com/questions/708061/qualcomm-atheros-device-168c0042-rev-30-wi-fi-driver-installation\
This brought my wireless connection to live, but I got disconnected frequently, about every two minutes. According to the network manager, I am still connected, but I can't even ping the DNS server (I can ping localhost). Sometimes the connection gets restored after some time, other times I need to 'disconnect' and reconnect again.
In addition, I purged the r8168 driver that I downloaded from Acer and installed the r8168 from the Ubuntu Software Center - no difference. I also replaced the Atheros driver with the one mentioned here (which worked for the other person facing the same problems - the driver is https://codeload.github.com/ajaybhat...nux/zip/master). For me, it did not work.
My regdomain is set to Germany (where I live). I tried to disable hardware encryption (nohwcrypt=0) and various other parameters for iwlwifi that were suggested in several forums and on askubuntu, which I don't really remember anymore (nothing worked, so I removed them all from the /etc/modprobe.d/ files, so they should be 'clean' again.
The other person (Sal) got his wifi working with just installing the Atheros driver and leaving the Realtek r8169 driver untouched. Do I need to get back to the r8169 driver (if so: how? just purging the r8168 driver did not do the trick) or does someone have a more specific suggestion?
Could it be that I just 'screwed up' my driver configuration and that a clean install, followed by just installing the Atheros driver could do the trick? Before I spend another couple of evenings toying around, I would be very grateful for some specific directions. Thanks again for your help!
