Rather than asking a vague, open-ended question, which you'll only get yes or no responses to, if you have an issue then describe it, and include relevant information about your system.

Please post the output of inxi -Fxz from a terminal and enclose it in code tags [code]output.here[/code]. You'll see the code tags icon </> when you reply. Also, please read this link: how to get help, especially section 5. It will tell you what we need to be told so that we can assist you.

I have four computers all running Linux mint with all the newest updates. All of them are having the same problem. Brave, Firefox, or Chrome all time out when trying to reach any website. If I run my windows machines everything is fine. I can transfer files via LAN just fine between computers and I tested BitTorrent which seemed to work without any drops. The problem seems to happen after having inactivity. After trying various times I can finally get it to work. Then after inactivity I have the same problem again. I think this happened when I updated to the newest Kernel - 5.4.0-67.

It might be worth running an older kernel and seeing if it works then. A new kernel may have some subtle change which is affecting your machine. Or you could do what I have done run a 5.8 series kernel

See if power management is on:

Code: Select all

 iwconfig 

IF it is, turn it off with:

Code: Select all

 sudo sed -i 's/3/2/' /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf 

Reboot
