I get 4/5 bars of WiFi connection in my bedroom which is 15ft away from my router and modem and my laptop indicates that it has Internet access, yet when I try loading Google my computer isn't able to load the page. If I get closer to the router/modem my WiFi connection goes to 5/5 bars and I do get internet connectivity. There are two somewhat thick walls in between. Any idea on why I can't load any webpages? How to solve it? Would a WiFi enhancer solve the issue?? Thanks
