Home wifi connects, other networks do not
by JPru from LinuxQuestions.org on (#5P5S3)
Hi LQ:
I have been running Ubuntu 18.04/20.04 for just over a year without any noticeable problems. I work in a busy environment that hasn't allowed me time to learn anything more than the most basic aspects of Ubuntu, and I have just found an issue that requires help to resolve.
My problem:
Wifi works fine from my home, but when I try to connect to a different network, either private or public, the wifi area of the notification bar says it is connected but I can't connect to any sites. I get a variety of error messages in the browser. The most frequent message is that the host connection cannot be resolved.
What I've tried:
1. A coworker who uses Ubuntu suggested upgrading from 18.04 to 20.04. I did this, but the problem was not resolved.
2. The same coworker suggested that I test my wifi by creating a bootable USB via Unetbootin. I did this, booted into a clean install of Ubuntu 20.04, and found that the problem is resolved. While this shows that my current installation has problems, my work environment can't be interrupted to rebuild my OS.
I need to find a way to resolve this networking issue without the need to perform a full replacement of the OS.
Thanks for the help!
