** UPDATE 12/03/2016: I still have not solved this issue. Is anyone able to help? ***
I've been having trouble with my Wifi ever since I installed Ubuntu 16.04 two months ago. There are several posts similar to this one on the forums, however I've not found any that work for me. Here are some similar questions which did not help me:
How do I get a Realtek RTL8723BE wireless card to work?
wifi connection keeps dropping in Ubuntu 15.10 - RTL8821AE
Let's get into it.
I can load about 1-2 webpages before my wifi disconnects. When my wireless disconnects, the Network Manager icon does not change its appearance, i.e. showing that I'm still connected. It will not reconnect on its own. I then remove/reinsert my driver using:
sudo modprobe rtl8821ae -r sudo modprobe rtl8821ae
I never have internet that lasts long enough to load an entire YouTube video or upload a 3.5 MB file to Dropbox. Yikes.
