Hello!
I have a problem with connecting of my wireless adapter to wifi network.
Please help.
I have access to Internet by WiFi-router only. (Distance for router is 1 meter.)
I can not change settings in this router.
I have wifi adapter TL-WN781ND.
Due of this table
http://linux-wless.passys.nl/query_hostif.php
driver is in kernel tree (find by "wn781nd").
I am using Fedora-24. When I connected the adapter to motherboard (PCI-E)
and booted the system, kernel created network interface (wlp4s0) itself.

As you can see I have short message "FAIL" without any hints about reasons of this.
It is clearly that my adapter "sees" the wifi network.
But he can not to connect to it.
I tried to change different parameters in my config file, but unlucky.
Please give me a hint, what I am doing wrong?
Why the command "wpa_cli" is failed when trying to connect?
I think it is not the bug into "wpa_cli".
I thinK I do something wrong. I am reading different forums during two weeks, but
I can not find the solution of my problem.
Please, help.
Thanks.
