After the last update I noticed that my download speed is very slow. Right now it's around 15MB/s and used to be around 100MB/s.
The problem is only with wifi.
There was a bug report somewhere in 2020 on Ubuntu's Launchpad with a similar bug that after updating the download speed on the machine was very slow, around 2MB/s.
How can I fix this and what info do you need to help?
