My wireless is too slow. How do I change wifi driver?

Hello. I just installed latest Manjaro 21 XFCE on an old Samsung laptop. I find my wireless speed to be too slow. I previously had MX linux 21 on this machine without any issues.
this is the output from a lspci -k. How do I change the driver to an appropriate one? Thank you in avdance.
