there are contacts between the wifi antenna and the logic board your 1st gen iPod touch - these contacts just join with pressure, not soldered or permanently connected. I'm guessing that when you dropped your iPod you may have dislodged the connection to the antenna?

I suggest opening up your iPod and checking the connections.

take a look at the 4th photo from the top in these pictures, or in the repair guide, about step 5.

I had a similar problem the end of the iPod that the wireless antenna connects to is indeed a ground of sorts it uses the case as the ground plate of the antenna. The frequencies of Wifi have a small wavelength and so its possible to fit into a small space. The little board thats stuck to the front/digitiser is the actual antenna. It is actually a PCB with one wire that snakes around itself you cant see it its in the middle of the board. There is one visible connection to the exterior connection. ie the little metal springy section that curves around the case exterior. Thats the ground plate connection. If you look carefully at the little board you will see what looks like a metal put attached to the board. That is a connector for an external Aerial you can get one of those if you have an old wifi laptop thats in pieces or something else that has had wifi. I have one from an old shuttle the connector is the same and you can fit the aerial onto the iPod boosting its range by about 80% I might add!!! The iPod aerial is poor beyond belief.

Anyway you can at least get hold of one of those aerials and use it for testing... Im not sure you would want to walk around with it connected tho ;) lol

Hope it helps

Try doing a HardReset by holding the power & home button continually until the ipod turns off then power it on normally. This is what i did and it worked perfectly after that! Hope it helps.

Had the same issue. I did a system restore and it worked, however you need to make sure to have the contents put in a back up if you use itunes.

I bought a used iPod with cracked touch screen and was told that wifi worked only to find it didn't. The iPod had been dropped on that corner and must have damaged the antenna section.

I found I could get connected if I put the iPod right next to the wireless router antenna.

But of course that is worthless. So I opened it up and found that the pressure contact looked to be not making contact so I stretched it out some so it would contact the copper circle land on the circuit board side.

This improved reception but apparently the pressure contact on the metal case side was compromised and broke off at the slightest touch.

I have since modified it but at the most I get 75 % signal strength and it is not reliable.

So I have been questioning the purpose of the gold antenna crimped affair and if it provides ground to the antenna or what it actually does.

I reassembled my 1st gen with a used replacement Gold contact(Mine was in pieces) and used metal frame. I still can not get consistent wifi. I notice that this replacement frame is not much better than my original frame at getting both halves of the iPod to close together tightly and was wondering if this could be a big part of the reason I have very little wifi range. Before the repair I was getting about 75 percent range 50 percent of the time messing with mechanical alignments. Now after replacing touch screen and replacing the Gold contact, I have to put the iPod right under the transmitting antenna to get connection. Does anyone who has worked on these 1st gens before know if the case halves have to be solidly snapped together to get good signal?

Update

I was wondering what that metal pot was for. I thought maybe it was the accelerometer but felt it was not in the correct location of the main board.

SO have you loosened and replaced the antenna portion that is stuck to the digitizer? I am guessing it would need some kind of electrically conductive glue or at least selectively applied glue since even the bottom side of this antenna has copper contact area.
