after installing Ubuntu 16.04 my new Laptop (Asus P2520LA) I can't solve a problem I have a with my wlan/internet, so I would be very thankful if you could help me.
The problem is, that after successfully connecting to my wlan, after some hours the internet drops out suddenly while I am just surfing on a website or something. The wlan connection to my router seems to stay intact but the internet is gone. (The "connected"-icon in the upper bar does not change but a ping is not possible).
After this, a wlan reconnect is not possible (via the icon) and the only possiblity I found to reconnect is rebooting or removing and adding my driver module:
sudo modprobe -r rtl8821ae && sudo modprobe rtl8821ae
In this thread a script was posted that collects relevant information for wlan problems, so here is the output of the script exectuted just after the internet connection has dropped:

########## wireless info END ############
There is another odd thing I noticed that might be relevant: After the internet has dropped out, I can disconnect from the wlan via the icon but I can't reconnect. But after executing the analysis-script, the reconnections works just fine.
I would be very happy if you could help me with this problem. If you need any other information, tell me and I will post it.
Thanks!
EDIT:
After some more searching, I found some posts/articles that describe exactly the same problem as I have:
Wireless disconnect issues Ubuntu 16.04 with RTL8821ae

Unfortunately, in some posts the problem stays unsolved and in some others, where solutions are posted, the solutions don't work for me, so I really count on your help.

So I think I fixed the problem now. If the dropout does not occur within the next days, I'll mark this thread as solved.
I tried multiple strategies that have been posted on different sites. Maybe it would just be enough to install new drivers ( -> paragraph 5), but I'll list up everything in did, just in case there might be dependencies:
1. Ignore IPv6
(No direct success)
source: https://ubuntuforums.org/showthread.php?t=2288456
Click on Network Manager -> Click 'Edit' -> Edit the wireless connection -> Click the IPv6 tab -> Set IPv6 to ignore -> click OK -> Reboot.
2. Edit wifi-resume.service
(No direct success)
source: wifi still sleeping when resume
Add the following:
close the text editor.
Now do:
reboot
3. Configurate Driver
(No direct success)
source: 16.04 LTS wifi connection lost randomly every 5 minutes
4. Install other drivers
(No direct success)

Check, if your card is one of the following models: rtl8192ce, rtl8192se, rtl8192de, rtl8188ee, rtl8192ee, rtl8723ae, rtl8723be, and rtl8821ae
Then:
Reboot.
5. Again, install different drivers
(Success!?)
