its not just the wifi. No internet connection works. Even the mobile data doesn't connect. Pressing on connect does precisely nothing. The connect to internet page where all the currently available wifi and mobile data connection are displayed doesn't open at all.
I just wanna know what that page is called or how to invoke it with command line.

I guess that it is a hardware issue (i really hope it's not). Because i don't remember doing anything with my phone that would cause this.
I'll wait for sometime, see if someone here can help out, or else flashing is the only option.
