Answer to: NO WIFI greyed out.I know this post is old, but maybe this information may help someone else out, I have repaired a lot of iPods and have run across this issue several times. One example I have in mind is an iPod 2gen that had gotten wet (the moisture indicator was bright red). I was able to bring most of it back from the dead, but was unable to get wifi to work...the wifi selector was grayed out under the settings. I took it back apart to look at it again.

But only the ability to charge the ipod was defective. The good news is that I was able to re-soilder a replacement doc connector on for only around two bucks. But I got to warn everyone, those pins are really tiny. Hope this may help you or someone else out
