After reading some of your sharing messages, I found that the information you provided are extremely useful, but I did not find what I need to know. I have just bought one Samsung Galaxy S4 model GT-I9500, after setting some applications and I have tried many times with the connection for Wi-Fi Hotspot. I want to connect the Wi-Fi hotspot with my Laptop just in case if I am out of the coverage area of Internet availability.
If any one have the same problem and it's resolved successfully, please kindly share with me on how to connect it. What I suspected my laptop does not have a Wi-Fi driver, but it's impossible, I could connect Wi-Fi Hotspot with GS2 GT-I9000 before I bought GS4.
Thanks in advance for your sharing the technique to connect Wi-Fi hotspot using GS4.
