Today I made a fresh installation of Ubuntu 16.04 on another computer. I have two issues related to wi-fi connection:
When I turn on (or restart) the computer it appears a message that confirm that I'm connected to the wi-fi connection. But it seems that the connection last about 30 seconds (I can start a google search but then I not able to access any other page or refresh the search page). In few words, it seems that I have wi-fi connection but no internet connection.
I have tried a solution that stated that restarting the network manager (e.g.
sudo service network-manager restart
) would work. When I try this, Ubuntu is not able to restablish the wi-fi connection at all.
The output for lspci -knn | grep Net -A2
is the following:
07:00.0 Network controller [0280]: Realtek Semiconductor Co., Ltd. RTL8192E/RTL8192SE Wireless LAN Controller [10ec:8192] (rev 01) Subsystem: Realtek Semiconductor Co., Ltd. RTL8192E/RTL8192SE Wireless LAN Controller [10ec:8182] Kernel driver in use: rtl819xE
Thanks in advance for any ideas to fix this. Have a good day.

When I tried to execute linux-image-extras-$(uname -r)
I got an error message:

@Lucas Czepaniki:
Hi, thanks for the reply.
I tried both commands (using ethernet as you suggested) and then rebooted, but it seems the issue is not fixed.
iwconfig
, and notice your device name,wlan0
for the following examplezgrep wlan0 /var/log/kern.log
. Have you installed thelinux-image-extras-$(uname -r)
package? Have you searched AskUbuntu forRTL8192E
