Greetings to all.

I use Linux Mint Cinnamon 20.

Two days ago, the power went out for a second. After that, only the Tor browser and the Telegram Desktop application can access the internet. The rest of the programs I normally use (Libre Wolf browser, a password manager, a VPN client, and the Linux Mint Update manager cannot access the internet.

This has happened to me a few times now, during the last year, and eventually it resolved itself without me doing anything. Simply one time I turn on the computer and everything can connect to the internet again.

I tried unplugging and plugging back both the router and the computer, to no avail.

I would appreciate any feedback.

When the browsers can't reach a web site. Can you get to them by IP? (DNS issue)
Proxy issue?

Hello teckk,

Thanks for your reply. You wrote:

"When the browsers can't reach a web site. Can you get to them by IP? (DNS issue)
Code:

ping -c1 google.com
ping -c1 142.250.190.78"

The first ping you write gave the result: "name or service unknown".
The second one seemed to work normally, it sent and receive a package immediately.

Regarding proxy, I do not know about it.


Cordially,

Ok, what does that tell you? When you can ping an IP address, but not a domain name?

Your DNS is not working or is misconfigured.

In your web browser, this will work too.

Good afternoon, thanks for your reply.

Very well then, I do not know about DNS. How do I fix that?

I've seen (numerous) Threads where resolv.conf 'broke'. (but I'm not expert) Try this:
