No internet (ish)
by Fitch from LinuxQuestions.org on (#6MJHK)
Having had a working Ubuntu Mate desktop for over a decade, dutifully updating and upgrading along the way (now on Jammy and Mate 1.26.0) I have had few problems.
Then 3 days ago, no internet.
I was even complaining to Vodafone (through the Vodafone fibre, with a telephone connected to the Vodafone router - wasn't thinking, just panicking).
Firefox, Chrome, Brave and Thunderbird mail all "No server" EXCEPT I could browse anything in my LAN, including the router and my NAS.
Trawling through the forums on a 20 year old laptop with fading screen, I found that "eth0" could disappear and be replaced by some weird label, in my case "enp63s0".
As advised on a forum, I changed /etc/network/interfaces to suit.
Shouldn't have bothered.
I then found somewhere else that I should alter /etc/default/grub and update/reboot.
Hey presto, I got eth0 back.
But no internet..
Out of desperation, I tried Telegram.
Lo and behold, it worked.
So I then tried my VPN, fired up my browser and everything came up as though nothing was wrong. Without the VPN it's back to "No server".
What's going on?
Can I just find my DVD and reload my network interface thingy, or is there another way?
