unable to browse internet with s4
I am connected to wifi but unable to browse the internet. I tried one of the fixes on another site and ended up spending 2 hours on the phone with tech support trying to get connected back to wifi (which disappeared during the fix). I am back on, thank goodness, but now reluctant to do anything else unless I completely feel comfortable after all of the trouble I experienced. Can anyone help? I looked at Daniel Garcia's post but feel that is too advanced for me to try on my own.
