This is not the standard WIFI question that has been floated around, and is kind of off topic, but at the same time.....not off topic. I am the proud owner of a fantastic Verizon Galaxy S4. Love the phone, switched from an iPhone several months ago. Here is the tricky part. My employer provides us with an open Wi-Fi. I have my own office. The Wi-Fi signal seems to stop at my office door. Everyone outside of my office with their iPhones gets the signal just fine. Inside my office with my Galaxy, I do not get enough signal to accomplish regular tasks. I also don't receive a strong enough data signal inside of my building. So, here is my question. I really need to figure out a way to either increase the signal strength of the wifi or figure out a way to make this galaxy s4 receive the signal better. Do those wifi extenders work in this type of situation, or one of those magic things you put behind the battery of the phone increase its reception ??
