Question Lgv20

[chileno]

I'm having problems with my lgv20 and my account with metro by T-Mobile. When I go to the store and hook into their Wi-Fi I can make calls but not receive them but when I hook into my wifi at home I can't place or receive calls. Is there a way to capture what settings I have in my home wifi and compare them with those to the store? Like a data dump and how to open it once I get it? Thank you for your time.
