Fast Question On WiFi

Friend took over a Laptop for me to “fix” & clean up some Junk files + set her IE back to its original default Font size. When her Laptop picked up my WiFI signal and I keyed in the security or password ,so that her Laptop can access the net. I have AT& T
Does this screwed up her WiFI access to her Laptop, when she gets home?- She has Comcast.
Answer #1
Not at all – what you set up is all keyed to your signal.
She’ll need to know her router’s security code (for when she gets home to set it up with her router), but your settings won’t interfere with hers.
