Iphone 3g doesn't recongize wifi recognized by other iphone

[leahmaria]

Hi,

I am new to this forum and would like to apologize if this has been asked before. I have an iphone 3g that doesn't recognize home wifi that is recognized by my other iphone 3g. The phone has already been through a re-set at the apple store. What could cause this? What can I do to fix it?

Thank you,
Leah

Does it see other wifi networks or just doesnt seem to recognize that particular one at home?
