absolutely not wifi uses radio waves to exchange information and connect to the internet which have no affect on human beings
Correct. And just to add a bit of info, EM waves are non-ionizing radiation. Therefore they do not affect genes or body tissue. The single exception to this rule is that, if they are *VERY* powerful, they can cause localized heating - as in standing directly in front of a huge and powerful radar antenna while is is broadcasting. A somewhat related issue is that microwaves can interfere with the proper operation of some heart pacemakers. The bottom line is that Wifi operates at a level FAR, FAR below those dangerous levels.
