Some commands and the output I receive from Ubuntu: I also saw it mentioned somewhere that it might help to completely shut down Windows and manually turn on the PC again, instead of rebooting from Windows and then booting into Ubuntu, but this also makes no difference for me. I did follow the following steps in Windows which I found somewhere, but this didn't fix the issue for me: Right click my computer and choose "Properties" I don't think it's a good idea for me to just blindly follow any such instructions from answers given to other people based on their output which may be different in my case, and rather just ask for my situation specifically here. I did find many other similar questions and answers, but most answers seem to be about specifically editing certain files or entering commands in the terminal based on output the specific user had. Then it'll work for a few seconds, which I can use to quickly browse to the page I wanted to go to. In can rather consistently fix this every time by manually breaking the connection (Ubuntu appears to think it is still connected, just Firefox can't actually find any pages), and re-connecting.

Most of the time, when I attempt to go to a new webpage for example, it fails. In Ubuntu, it appears like I can only actually have the connection work for a few seconds, up to maybe a minute.


The connection works perfectly fine in Windows. I have recently installed Ubuntu 16.04 for dual-booting on a desktop that already had Windows 10 installed, and I'm having network issues in Ubuntu.
