I was wondering if anyone has had the same problem: I upgraded from LTS 18.04 to LTS 20.04 with no problems. Once I restarted this morning, I no longer had access to the internet. It shows that I'm connected wirelessly, but if I try to open any web page, I get that the Server could not be found. I've had this problem before when I installed LTS 18.04, due to the booting process, but now it seems to be something different. Can anyone assist?

Update: Here are the results of the commands requested by chili555:

  • Please edit your question to show the result of the terminal commands: ping -c3 8.8.8.8 and also: ls -al /etc/resolv.conf

  • Hello. Thank you for your help. It appears that I know have access to the internet, but it is painfully slow and some websites don't even load. Could this be associated to the problem we were trying to resolve, or a new one? Feb 19 at 18:58
  • I think it's a new question. No access is solved and it isn't the same as slow access. Please start a new question, leave the link here and I'll be happy to assist. Please include the results of the wireless script: askubuntu.com/questions/425155/…

  • After trying a few more fixes, I updated and upgraded the software via the Terminal and lost internet again. Feb 19 at 21:56
  • In addition to my comment above, now when I try to ping, I get that the Network is unreachable. Feb 19 at 22:15
