I have been using Ubuntu (18, 19 and 20) for the last two years. Everything work fine except for the wifi, which randomly stops working. Sometimes I can just turn off and on the wifi and it comes to work until next random crash. However, other times, when it happens, I cannot turn off wifi, it seems like the system breaks, I have to hard shutdown the laptop and after boot it works again.
