Description Dumindu 2016-10-22 18:43:10 UTC
Description of problem:
-----------------------
I am using a TP-Link TL-WN822N 300Mbps wireless USB adapter. Every 1-3 minutes network is getting disconnected and after some time network indicator on the top menu is changing to question mark icon.


Version-Release number of selected component (if applicable):
-------------------------------------------------------------
I noticed this on Fedora 23, 24 and 25 beta. I tried different tweaks like disabling IP6 and etc but none was worked. Recently saw Fedora 25 is going to support raspberry pi models as well, so please try to fix this issue in a proper way instead suggesting tweaks for some adapters.   


How reproducible:
-----------------
use a TP-Link (TL-WN822N 300Mbps) wireless USB adapter and try


Steps to Reproduce:
-------------------
1. Install Fedora 25 (or 23, 24) on a desktop pc and use a TP-Link (TL-WN822N 300Mbps) wireless USB adapter to connect to the internet. 

2. Navigate on random web pages and test 


Actual results:
---------------
Network is getting disconnected after 1-3 min. 

But when I was inactive, screen is getting off and locked. But in this case network is kept as connected in many cases.


Expected results:
-----------------
Network should not be disconnected.
