Hello. I'm having this problem for a long time now and I just got tired of it.
Anyway, I have a wifi extender from D-Link (TL-WA850RE) in my bedroom and the modem is about 6meters always from the modem.
It works perfectly on my Samsung S3 till my father's smartphone (it is an old model, but I don't remember which one is now) and it connects to the Extender wifi (it has a different name from the "main" wireless). When this happens he can use this wifi perfecly fine but I can't connect to it anymore (no error msg), not even after he disconnect from the extender wifi.
PS.: sorry if the language I used is not correct. English is not my mother language and this subject is not one that I usually talk about in English xD
