Any wireless program/driver would be obtained from your PC makers web site, more than that I cannot say since you dont mention the make/model of Laptop, other than Samsung
BTW programs dont use memory, accept when they are running, they do consume disk space. And if you are that short of disk space then there are other things you need to be doing, like get a larger drive. And you dont remove/uninstall anything without knowing what it does and the consequences of doing it
