'Activation of network connection failed' error on Ubuntu 20.04 LTS

'Activation of network connection failed' error on Ubuntu 20.04 LTS


Hi all, Brand new linux user here. I installed Ubuntu 20.04 LTS 2 days ago on and old desktop that I haven’t used for years. I have not been able to get my WiFi connection working in the Ubuntu OS. Some notes that may be helpful: – I am receiving the error ‘Activation of network connection failed’ – I have tried connecting to a second WiFi connection with the same error – All other devices are able to connect to same WiFi router without issue (windows PC, Mac laptop and mobile devices) – Wired connection is working fine on the Ubuntu desktop – I don’t have any other OS installed on the machine so am not able to test the wireless connection from Windows – Wireless card I am using is a ‘Qualcomm Atheros’ I’ve been reading through the other related posts on this forum and have not been able to resolve the issue. I found this old link on this – https://ubuntuforums.org/showthread.php?t=370108, which is a very old link, but I could not see a new method I should be following. I went through the steps and I have attached the log file of my wireless info. Thanks in advance and appreciate any support you can provide. Attached Files wireless-info.tar.gz (17.5 KB)
