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.
The wifi assemble is at the top right corner of the device, right behind the black shield that is visible on the backside of the outer stainless shell. If you remove the three screws that holds the entire top pcb assembly in place, and gently lift the ribbon wire that connects the top and bottom half, on the backside of the top PCB assemble, you will see a small rectangle metal cover. This covers the broadcom chipset for the wireless. In this particular iPod, I noticed some scorching on this cover. I gently pried the cover up from one of the lengthwise sides. Be careful, this cover is soldered at 4 corners, and I had to break two of the solder points to lift it just high enough so I could see underneath. At this point, I saw a couple blown resistors next to the broadcom chip.
I did not attempt to replace these components, however, I did have a definitive answer on why the WiFi was not working on this iPod.
Hope this saves someone some time in diagnosing a wifi issue after they have performed the other various common fixes to this issue that are found on the web.
