I'm using ubuntu 16.04 some times system wifi icon is turned into lan connected icon and if i restart the network manager that doesn't show any available wifi some times restart will solve this issue but i need a exact problem and proper solution for this issue.

Some analysis of the problem will be needed (otherwise we're left to guess). Wireless hardware (chipset and driver) details might be useful to start with. Open a terminal and do

Code:

/sbin/lspci -knn | grep -i net -A3

Also, you could monitor the NetworkManager logging, and capture the output when your wireless connection stops working. I'm not an Ubuntu user, but I think 16.04 is using systemd, so try monitoring in a terminal window like this

Code:

sudo journalctl -fu NetworkManager

Report back with the relevant output when your connection drops.

It may well be a power management issue.

Just in case this is relevant to your situation....

The best solution that worked for me (in Ubuntu 16.04LTS) is to change the value of wifi.powersave located in /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf from 3 (enabled) to 2 (disabled).

This effectively makes the effects of sudo iwconfig <interface> power off permanent.

are you talking only about the icons?
is everything working normally otherwise?
