I've had this laptop for a few months now, though secondhand, my sibling gave it to me as she recently switched laptops, and it's been pretty good! Though, for the past couple of days, it keeps randomly disconnecting to the wi-fi and it's getting to my nerves. It also started stuttering (?)/glitching at random times (despite upgrading more ram). Does anyone know why this keeps happening? Thanks in advance!
