Hi,
I had this exact problem and did everything I found on the net to solve the problem, but was not successful.
I finally arrived at the cause of the problem and was able to solve it finally as my PC was always turning limit after a short successful connection to the internet. My all other devices were connecting fine though without any problem.
The problem was the wifi range extender that I was using in my room. For some reason it was not compatible with this particular PC unlike other devices that I have. So what I did is that I had the main router (the one connected to modem of my service provider) in my room and the range extender in the faraway room and now all devices are working perfectly. So I believe that this problem happens with some PCs not all and the cause of the problem is the booster device that I used to enhance the signal.
I hope this is helpful.
