I'm assuming your having your wifi switch on button greyed out.
If so, have look here.

Mine did that take off the back and use a hair dryer on it. Turn it off first. Mine works now but it keeps going off most of the day so I put plane mode on then off then on then off. It's been ok so far today!

I have got a new part, I'm going to try that later!!

Hi, Wifes iphone 4s had the grayed out wifi issue. heated it up with her hair dryer untill warning sign appeared on screen you will not be able to hold it by hand (applied heat to the edge and most to top of phone not to screen ), put it in a freezer bag to protect it from moisture, put it in freezer to cool down for a few minutes. been working fine since Christmas eve. This is a hardware issue and Apple do not care!
