Greetings,
I just installed Linux Mint (Cinnamon) onto an older computer. This is my very first experience with Linux and I have to say, that I am quite surprised how it was able to revive this old computer. It replaced Windows Vista. I installed a wireless NIC on it sometime ago and it worked just fine on Windows Vista. However, in Mint it randomly disconnects, sometimes fails to reconnect, and is quite annoying. It seems to occur more often when I am a little more demanding or have several tabs open. So far I have only used Mint to browse the web and watch videos. I want to install Microsoft Word onto it and do not wish to ask much else out of it.
Now it looks like this is a common issue. I see other people posting complex lines of text that I am assuming they are receiving from the Terminal. I am very comfortable using these types of systems, but have no experience with the Linux "Terminal". I am guessing it is very similar to a Windows Command Prompt where you can modify things and request information about your system. At least that is the way it looks. Anyway, I just wanted to make that clear before anyone tried to help me. Also I appreciate any help in advance. I am honestly pretty excited to have my old computer back up and running with an operating system I did not expect much from.
I would love help attempting to figure out my problem and look forward to becoming more familiar with Linux in general.

Re: Wi-Fi Randomly Disconnects
A couple of things that may/should help.
1) Disable wifi powersave feature.
Open a terminal window.
Enter
Enter your password - you don't get visual feedback as youu type it.
This command opens the /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf file in nano, a terminal based text editor with root privileges so you can edit it.
Change
Hit
Then enter
Turn your wifi off and then back on.
Enter
2) Disable IPv6
Open the Network Connections app from the menu.
Select your current connection to your SSID, click Edit. Select IPv6 Settings and change the Method to Ignore. Hit Save.

to wifi.powersave = 2
Hit
Ctrl X
and then Y to confirm you want to save the changes.Then enter
sudo systemctl restart NetworkManager
Turn your wifi off and then back on.
Enter
iwconfig
. This should confirm the Wifi Powersave is off....2) Disable IPv6

Re: Wi-Fi Randomly Disconnects
Thanks for the response. I am also noticing something else that might be worth mentioning. Whenever the Wi-Fi does get disconnected, either randomly while surfing the web or by me it keeps attempting to reconnect and fails. Then I am left with the two disconnected wires icon at the bottom right. Could this mean that when it disconnects it is attempting to connect via Ethernet which is not connected?
Because when I got to the step about disconnecting Wi-Fi and reconnecting I could not reconnect. I restarted to resolve the issue. Also I just confirmed that Power Management is off now. I have not been using it long enough to check for problems, but seems like mine might be something different. For instance, I am pretty sure that if I disconnected from the Wi-Fi right now I would not be able to reconnect. It does sometimes resolve without a restart, but that is the easiest fix.
I think I already mentioned it but the wired NIC is integrated into the motherboard and the wireless NIC is something I added.

Re: Wi-Fi Randomly Disconnects
Okay so I have been using the computer since yesterday and a little bit today and so far no problems whatsoever after turning off power save feature. Why is that even there in the first place? Is it for people that install Linux to a mobile device with a battery?smurphos wrote:A couple of things that may/should help.

Anyway, it looks like this resolved my issue. Thanks Smurphos I appreciate it.

It is there because of https://bugs.launchpad.net/ubuntu/+sour ... ug/1557026

Re: Wi-Fi Randomly Disconnects
Hi
I have followed the helpful post from smurphos and it worked ok for a time but the problem still persists for me
I keep having to enter sudo systemctl restart NetworkManager in the terminal
I would be grateful for any helpful suggestions. Thanks for reading
inxi -Fxz command gave :
Edit: after one month and no further responses this problem is still there for me. I have to restart the Network Manager at least once every single session - tedious
Suggestions still welcome. Thanks
Edit 2: Two days ago I found that I had installed the package wicd alongside the MATE standard wifi software. After uninstalling wicd there has been no random disconnection.
