Dell Latitude 3490: Problem with ath10k QCA6174 + Ubuntu 20.04

in flag

happy new year!

I own a Dell Latitude 3490 and since I've changed the OS from Windows 10 to Ubuntu 20.04 i've found some problems with WiFi connection. Connection drops, connections failing, slow internet speed (my link is up to 300Mb/s but on that Latitude only reach ~40Mb/s). I've followed some guides here on Askubuntu and over the internet but nothing changed this scenarios. Can someone bring me a light up, please?

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
