In ubuntu 14.04, why does my internet connection keep disconnecting?

Question

what could be causing repeated internet connection dropping on a wireless network (the wireless does not disconnect), which can be momentarily fixed by disconnecting and reconnecting in 14.04? Here is the wireless info list http://pastebin.com/ZgGxQ9qE

I am using a USB TP-Link TL-WN821N wireless adapter (Realtek rtl8192cu).

Please [edit] your question and add output of `lspci -knn | grep Net -A2` terminal command. — Pilot6, Aug 19 '15 at 16:14

@Pilot6 - hi, I tried that command but it prints nothing on the terminal, if I type just `lspci -knn` there is a long list. — maou, Aug 19 '15 at 16:24
@Pilot6 - yes, it is a TP-Link TL-WN821N. But the wireless connection does not disconnect, I can ping the router at its ip address. — maou, Aug 19 '15 at 16:30

@Pilot6 - hi, I'm doing as you suggested, but my internet speed isn't slow, it disconnects completely, even though the computer is still connected to the wireless network. When I disconnect and reconnect the internet is back and the speed is as fast as ever. — maou, Aug 19 '15 at 16:35
It does not matter. There may be various symptoms with the default driver. — Pilot6, Aug 19 '15 at 16:37

Install the driver by running in terminal:

sudo add-apt-repository ppa:hanipouspilot/rtlwifi
sudo apt-get update
sudo apt-get install rtl8192cu-dkms linux-firmware

Then reboot.
