I have the same problem with a fresh install of Ubuntu 20.04 LTS release on a Dell Latitude E5440 with Intel Wireless 7260.
Also, the wifi connection is quite unstable and would sometimes freeze altogether, until I disconnect and connect again.
With Ubuntu 18.04 on the same machine I have never had any problems before.
