Hi guys, I've write a theme about this problem before, but do not say the question correctly. I have Microsoft Lumia 535 Dual Sim with Windows Phone 8.1. So i have problem with my home wifi. When I connect my phone to my router it says that the wifi is secure, am connected, but when I try to use the internet it says ''cannot find server or dns error''. I research for the answer in google, I've saw so many solutions like ''turn on the plane mode and then turn it back off'', ''do a hard reset (which i do twice)'', ''use static ip(got no option like that in the settings)'' and stuff... If somebody have got this problem and find a solution please tell me. It's a pain in the ass to have wi-fi on my home and cannot fix it...
