WiFi Password Issue

cn flag

Any idea why my Ubuntu 20.04 has recently started asking for my WiFi password in the middle of online sessions, usually resulting in disconnection? This occurs repeatedly on some days and not at all on others, with no pattern that I can detect. It's a private password-protected home network with only a laptop and printer and there are no other operating systems installed. It's set to WPA and WPA2 Personal security and won't let me change that setting. IPv6 is disabled.

I don't know if this is something you can test... but if you connect to some other WiFi, like at a café, does this problem still happen? Also, WPA2 is pretty standard. I'm a bit surprised you can't change it, but it's a fine default. I use Kubuntu 21.10 with WPA2 Personal, so it should work just fine.

*"set to WPA and WPA2 Personal security and won't let me change that setting"* - What do you need to change it to? What kind of authentication is needed from your home network?

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

I didn't think WPA and WPA2 Personal security was the problem, because it worked fine until recently. I just wanted to see if changing it would make a difference. What should I be looking for in the Logs? Another question: Would Network Manager detecting other networks in the neighborhood trigger an authentication request?

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.
