Iphone 3g won't pick up wifi signals?

[iphonenoob]

My iphone 3g won't pick up wifi sometimes and whenever it does the signal is very low. For example, my phone is beside the router and the signal is low-mid. How can I fix this? Thanks.

Did you get the phone wet? This happened to my wife's 3g after she washed it. never was able to fix it.

If you never got it wet, I'd suggest going to an Apple store. While it's out of warranty, they may be able to repair it, for a price.

I'm not sure if it got wet or not because I bought it off of someone. If i replace the wifi signal flex cable, would it fix the problem?

Maybe, but if your username is any reflection of your skill, i wouldnt cause you have a good chance of making things worse
