Wifi doesn't work Ubuntu 20.04

us flag

Im very new to Ubuntu, wanted to get into it because I want to learn web development and so I'm also new to all this coding stuff. I only installed it yesterday and I'm having trouble with wifi. It either won't connect at all, or won't stay connected for long. I've had some stretches where it worked for 20-30 minutes at a time but then disconnected again and refused to get back on. My wifi card is intel 3165.

Intel WiFi card are generally a delight to work with, they just do, no user actions required. The problem is likely to be in your access point. Make sure you have the recommended settings WPA2-AES only, no mixed mode, no TKIP.

Welcome to Ubuntu, I'm sure you will enjoy it. It can be a drag to run into issues right at the start. However, have you already looked for solutions to your issue, and tried solutions that other people have found? For instance, if I search on "intel 3165 linux" I get [How can I install Intel Dual Band Wireless-AC 3165 drivers?](https://askubuntu.com/questions/672700/how-can-i-install-intel-dual-band-wireless-ac-3165-drivers)

I've tried to change my router settings, it seems to have helped a bit, but it didn't solve the issue. The answers in that link haven't helped either, I'm still getting disconnected from wifi very often.

Look at the logs! `sudo journalctl -b 0 -u NetworkManager`. Read `man journalctl`.

Well, what I managed to find out is that the fault has to be in my router, as I can connect to my mobile hotspot with no problems. I've tried playing around with settings a bit but nothing has helped so far.

Does it work if you install [Ubuntu 20.04](http://old-releases.ubuntu.com/releases/20.04.0/) version? Not the 20.04.1 or newer. I have the same Wi-Fi card and it broke after a kernel update which I had to roll-back.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
