I updated yesterday, and when I started my computer today the internet was not working. It's working on both my phone and my work laptop, so I know it's not a problem with the network itself.

When trying to connect to my wifi the access box where I type my password is gone within a second so that's no help.

I tried changing the kernel in grub when I restarted but it did not help.

uname -r : 5.15.0-52-generic | 5.15.0-53-generic (after restart, did not change default kernel)

lspci | egrep -o --color 'network|ethernet':
06:00.0 Network controller: MEDIATEK Corp. MT7921 802.11ax PCI Express Wireless Network Adapter
07:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8125 2.5GbE Controller (rev 05)

Ubuntu 22.04.1 LTS

Edit: I tried changing managed=false to true under [ifupdown] in the network manager.

Edit #2: I tried removing wireguard which said it was connected when typing nmcli

Both my wired and wireless connections are still failing.

I "fixed" it with a workaround. I connected to my wireless network as a hidden network. My wired connection is still broken but at least I have a connection.

You are probably using NetworkManager. Take a look at `/etc/NetworkManager/NetworkManager.conf`. Does it say 'managed=false' somewhere? Then change it to "true" and restart NetworkManager. It happens (rarely but annoyingly) that an update changes that to false.

I tried doing that (it did say managed=false under [ifupdown] and I changed it to true, then I restarted my computer and it still does not work.

The reason I restarted my computer was because I ran: sudo service network-manager restart Failed to restart network-manager.service: Unit network-manager.service not found. (Was not allowed to edit my comment)

In 22.04 that should be `sudo systemctl restart NetworkManager`.

This did not work either

If someone has any ideas I'd be more than willing to try them.

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.
