[Q] Oneplus One WIfi issue on Multiple ROM Builds topic

Hi I'm new to Oneplus One. My friend just gave it to me. I can't connect to any wifi connection. It also having a hard time
detecting one. I have wifi in my home which I'm using for my laptop and it works fine. Also tried rebooting it but no good.
I also tried flasing different builds :

cm-11.0-XNPH22R-bacon-signed-fastboot.zip
cm-11.0-XNPH33R-bacon-signed-fastboot.zip
cm-11.0-XNPH44S-bacon-signed-fastboot.zip

Still not working. Is this a known issue? I've been digging in the internet for almost
a day and can't find a fix for it. I'm living in the Philippines by the way. Hope you can help me.
I'm using a Sandstone Black 64GB Oneplus One.
