I have Asus Rt n12 c1 router which was working fine for 2 years. But yesterday stopped working suddenly. My modem IP is 192.168.1.1 while Router IP is 192.168.2.1 . I can't even access modem page now . Only router page can be accessed which displays Internet disconnected. But when I connect ethernet cable to laptop , everything works. I took router to my office and plugged ethernet cable , then it worked . So there is no problem with my Interenet (as it works on laptop) and neither router (it worked in office) . But still internet can't be accesed through wifi at home. What can be the issue ? It was working for 2 years without problem.
