Wifi won't work on my Lg

[PureAmy]

Ok so basically It works everywhere else except on my own wifi wich is really annoying. I did send it 2 times to the company. I have been doing everything possible = enable wifi go to advance and etc, I'm am on the very edge to throw this phone down the window so I am here to seek additional help. My router is a linksys cisco not too old not too new. If anyone fixed it by miracle please share.

Can I ask which protection? (WPA, WPA2, WEP...) But I don't think it's the protection - can you please explain it better? What happens when you're connecting? Did it say "Connected"? Or what?

Different Wifi pwd gt different connections. Try WEP protection it works vry well for me.
