Wireless Connection problem (Ubuntu 21.04)

I have a peculiar issue with my wi-fi connection. The title says that it's 21.04, but it happened on 20.04, so I think it's some sort of local issue, which I cannot pinpoint.

I have another machine that runs Ubuntu 20.04, a Windows machine and several Android phones that can successfully connect and get internet access, however this particular machine can only connect, but does not have internet access and can't even reach the default gateway.

Please help me pinpoint the issue, because everything seems to be in order, based on what I've read on other threads and as I tried to troubleshoot, but I don't understand all these low level details, and obviously the issue is local.

Try `sudo sed -i 's/wifi.powersave = 3/wifi.powersave = 2/' /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf` then reboot, it might work with power management disabled

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.
