Only Home Wifi Not Found

[Dext3rs]

Others wifi are displayed on my phone, and I can connect any wifi I want with no problems. but recently, a few days ago, my xperia U cannot find my home wifi, ID rahiza07, others neigbours and my other samsung hotspot is found, but I just couldnt find my home wifi, all the other device has no dificulties to detect home wifi, only this xperia U. I hope you understand. it's like I've filter the wifi, but i didn't, why would I do that.. I have reset and hard rest everything twice, and even upgrade it from 2.3.7 - 4.0 latest firmware available at the moment. but still nothing. the conclusion is. My Phone Not Detecting My Home Wifi, while others device can. weird ~

Hi and welcome to the community! Since you're new please be sure that you have checked out our Discussion guidelines.

Do you have an active SIM card in your phone? 

I would suggest that you first of all try to change the channel on your router. See more information in the link that Alexdon posted above.
