I have a Lenovo ThinkPad T440s which is having issues connecting to the wifi. The wifi on the laptop is picking up wireless networks, but will not connect. It will go through the process of Configuring interface. After it attempts to connect a pop up appears that the connection has been deactivated. System has a Realtek Network Controller in it (RTL819EE). Any help, would be appreciated! Thanks!

It could be a buggy driver. It could be a lot of things. There is a script on the Ubuntu Forums. You can see it here. It will create a text file called wireless-info.txt. You are then asked to post it on pastebin. There instructions are easy and listed toward the bottom of this link. It will also have info in the file that people can use to help you here in this forum. I would also recommend seeking help in Ubuntu forums as this issue is probably not Kubuntu/distro dependent.

Good Luck!In 2012 I wrote a wireless script for gathering information to help diagnose wireless issues. It is now hosted on the Ubuntu Forums Council github account and today it is used in many forums. It is also posted on Ask Ubuntu here and has helped thousands of people get their wireless issues fixed over the years. I still help test it and maintain it though I have a friend by the name of krytarik that is the person that writes all the code for the script these days. -
We need to know a little more about the wifi card in that machine.
please go to a terminal and type these commands, one at a time, and post the results back here.
(just copy and paste into terminal and hit enter.)Code:lspci | egrep -i --color 'network|ethernet|wireless|wi-fi'
I also recommend you install inxiCode:ifconfig
once installed go to a terminal and enter this code.Code:sudo apt install inxi
post results.Code:inxi -Nn

Isn't your driver rtl8192ee? I couldn't find any reference on the web to rtl819ee

Thanks everyone, so after I posted this, I decided to go back to Ubuntu, which was working with out issues. I reinstalled that hoping to upgrade to Kubuntu Desktop. I had the exact same issues with connecting to wifi. Network would show up and get a similar issue when connecting. I decide this afternoon to install windows on it and see if I had any luck with it. Same issue, it will show the wifi network, but not allow me to connect. It's very odd. I'm going to trouble shoot some more and will keep you posted.

You could also compile your own proprietary standalone driver instead of using the kernel driver:

You will need to have compile time dependencies installed like build-essential. There may be others. I would also recommend using the DKMS instructions so that the module rebuilds if the kernel gets updated.
If you are on windows, are you using a proprietary driver or is windows just using its own driver? You might try using a proprietary driver instead.
Either way, good luck!Comment
