iphone 3g wi-fi problems

I could not get a hotel wi fi recently and the receptionist took my phone and did something to it. Now I can't get my wi fi network at home. I have it clicked and when I compare the settings to those on my computer, there is a difference in the address.

I can't figure out how to fix this.

Can someone help me, please?

Can you take a screenshot? (hold down the power then quickly press the home button)

My guess is the receptionist set it to manual. Set it back to dhcp and see if that helps.

I fixed it! I did a hard close and restarted and it's back on. Thanks for your quick reply.
