Network connected, but no internet
by rocketfuel from LinuxQuestions.org on (#5C8GX)
Hi all,
I'm beyond frustrated, and haven't been able to solve this problem with the help of Google.
I have no idea why, but after shutting down my machine and booting it back up, my network interfaces (both wired and wireless) are completely borked. Both wired and wireless connections will connect to my router (and Ubuntu will even see the printer on my network), but I can not connect to the internet. I've tried digging around in ip link, and the only thing odd that I can find is that the mode is set to "DORMANT" instead of "DEFAULT." Changing the mode does nothing.
My /etc/resolv.conf file reads: Code:nameserver 127.0.0.53
options edns0 trust-adI can ping 127.0.0.53, but all other pings (8.8.8.8, yahoo.com, etc.) fail with 100% packet loss.
One more odd thing: the system tray in the top right always shows a wired connection, and no longer shows my wireless connection.
I'm at my wits end. Any help would be appreciated.
EDIT: When booted into the LiveCD, networking works fine. All other machines on my network are working as expected.
I'm running Ubuntu 20.04, with the kernel updated to the latest version.
