Wifi card on ubuntu frequently keeps dropping connection/

Question

for a few weeks my wifi card keeps dropping connection with router once or two for an hour, it usually last for few minutes and reconnect. I'm using Ubuntu 20.04.4 LTS. Don't know if it matters, I'm using bluetooth headphones but I used them before while my network worked perfectly. Wifi on windows and on my smartphone works well.
