One time I was going to use the wifi but it won't turn on. It's like it's between on and off. I did the first method in here: http://techblogpremium.com/samsung-galaxy-s-duos-s7562-wifi-fix-method/ but it's still not fixed. For the second method, I can't find any reliable websites to download the "Android wifi fixer 2.8" so I didn't do it. Is there any other way to fix the wifi problem? By the way, there is no problem with the wifi modem or internet.
