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?
