Please Help!

this asus laptop just finish REFORMAT.
OS: Windows 8.1 x64
my problem is the wifi. it can detect the neighbor's wifi.
but it cannot detect my own wifi.
and we have a different subscriber with my neighbor.
i am currently using PLDT FIBR 5mpbs.
and my neighbor uses SMART and SKY CABLE.
this laptop can detect that wifi connection but isn't detecting mine.
i already try to download every available driver that can found in ASUS.com official website but still it won't work. i already try using DRIVERPACK 2015 software.
to those who knows how to deal this problem.
please let me know.
thank you very much!
