Had to do this for my wifey's iphone.
+1 about the reset.
Mine connects fine but I've noticed as well that the signal strength indicator seems to show less of a signal than before and seems to fluctuate more.
I don't know if this means it's more accurate/updates more than before!
My 2G iPod Touch's WiFi has been ruined ever since the update. It was perfect before the update, and for the last year, and immediately following the update it fluctuates wildly and disconnects constantly.
There are more and more people writing about it at the official Apple Discussion Forums now.
I tried everything in the first few days as far as forgetting and resetting network settings on the iPod, restore, etc, nothing worked. I tried everything you can possibly imagine in messing with my router (all other wifi devices continue to work fine).
One person claimed to have downgraded to iOS 3 and had his WiFi return to normal functioning.
One person's iPod no longer even registers that his WiFi hardware exists in his iPod.
Every thread ends up with a guy who keeps telling people to reset and reconfigure etc etc but that doesn't work for anybody. Most of us do all those things first before we come to a forum anyway. It's not in the router, it's something wrong with iOS.
Hopefully Apple fixes it, and it's not one of those things like they claim to fix it but never really do. Either that or let us go back to OS 3.
Even Safari and the App Store crash constantly under iOS 4. It's a mess for me, and many others.
I am facing the same problem. Normally IP address for all clients in my home network should be 10.0.x.x. but on my 3G iPhone shows 169.254.243.133. I try to reset all network many times but it does not solve the problem.
I have try to connect other wifi networks, office and coffee shop, it still can not connect to the network and IP address is still the same 169.254.243.133.
What should I do next?
I downgraded my 2nd gen itouch back to 3.1.2 because of this issue. No problems with wi-fi now...
I was also annoyed that my iPod Touch 2nd Gen's wifi signal has dropped dramatically after the iOS4 update. I've tried everything and no go. What I have noticed is that it drops down to one bar but never really disconnects from my router. When I use anything internet related on the iPod the signal goes full strength. Opening Safari and immediately accessing a web page returns the signal to full. Using Mail returns the signal to full. Using the iTunes store and Skype also returns the signal to full. As soon as I stop using anything web related the signal drops down to one bar.
So as far as using the iPod Touch I have no problems with any dropped signals so I've come to the conclusion that it's a power saving feature of iOS4 to protect the battery from draining. I'm just asking for others here to check their iPod Touch and see if it behaves the same as mine.

I have the exact same issue on my touch 3g 32GB. I was up at the apple store dropping off my brother last night to stand in line for an iphone and could not connect to there open wifi. I got the same 169.x.x.x address. I have tried to assign the IP address manually with no change. There is no way they can tell me this is an issue with the access point because I can not connect to theres!! The thing that really bothers me is that I can not downgrade because a I have a newer model so I am stuck until they decide to release another update.
Hmmmm.... Are you still under warranty?![]()
