    All right.
    So I downloaded the program and the result is:

    Thu Jul 29 17:06:22 my user name-iPhone kernel[0] <Debug>: AppleMRVL868x Join Failed, AP: @ 0x850d3800, BSSID = 00:24:fe:5c:7e:f9,
    rssi = -55, rate = 54 (100%), channel = 6, encryption = 0xc, ap = 1, failures = 1, age = 21, ssid[ 7] = "Rakhaus"
    Thu Jul 29 17:06:23 my user name-iPhone kernel[0] <Debug>: AppleMRVL868x - mapJoinStatusCodes(): Timeout waiting for Authentication
    response (2), mapping to IEEE status 16

    I am not a developer nor that much into software, but to me it looks pretty similar.

    So either my iPhone doesn´t detect or receive any authentication response or the routers don´t send them?

    Would someone care to share how to actually use iPhone Configuration Utility to get these results?

    I'm not sure exactly what is causing the authentication timeout, but I'll bet you that sticking the phone in the freezer for 15 minutes in a bag, then trying again, will temporarily fix it.

    I've got my appointment set up with the local geniuses here and will post the results.

    1. Download the app. Start it up.
    2. Connect your iPhone to your computer. It may be a good idea to have iTunes closed when doing this.
    3. Wait for your iphone to appear in the Configuration Utility's sidebar. Click it.
    4. There should be some sort of log or console tab, or section somewhere in the window, click it

    This is a live, real-time log. You will see things written to it as you perform actions on your iPhone.

    5. Set up the your iPhone to the point right before you are expecting a problem to occur (for me it was right before I hit the button to send my password).
    6. Clear whatever is in your log to remove any data that isn't pertinent.
    7. Perform the task that you expect a problem to happen.
    8. Capture the output, and post! -- don't be overly verbose with the log data you post, focus on what seems to be the problem.

    Have you tried entering the security key from your router in the password field when prompted to join? That worked for me.

    Just got back from the Apple Store.

    The Genius did some basic diagnostics on my 3G and determined that nothing was wrong with it except for not being able to connect to a wifi network (couldn't connect to the store's network). He told me that Apple was aware of issues with the iPhone 3G running iOS 4.x and said they are working on an update. I asked what the update was to address, he said performance issues, but not wifi. He said that I could replace the phone for $199. I asked him to ask his manager to see if I could get a refurbished 3G, which he did. After 15 minutes of waiting at the Genius bar, he came back saying "today we're going to do you a solid", and give me a refurbished iPhone. And that's exactly what he did.

    The iPhone 3G I got has 3.1.3 installed on it; I'm updating it with my latest backup as I type. The only other thing to note is that he said "No", when I asked him if I should upgrade this phone to 4.x. He was of the opinion I should wait.

    So, all's well that ends well. Thank you, Apple for giving my story a happy ending (or, does that sound like I'm a suck up?)!

    ARGHHHHHHHH!!

    iPhone 3g. Had since December and the WIFI has been brilliant. Started using the phone a lot in the car on the way to a conference, and this required Airplane mode. Now that might be a co-incidence, but since I got back from that trip I cannot connect to ANY network.

    I tried the freezer trick which lasted about ten minutes. But nothing since.

    I found this whilst trawling for fixes though:

    +"THIS IS NOT A MAJOR HARDWARE OR SOFTWARE ISSUE. BUT IT IN FACT IS A HARDWARE PROBLEM, I for a while i had wifi problems where is had no little to no access unless i was about 5ft from the wireless router. Well i replaced my screen because it was horribly cracked, and a ribbon connected cable came completely un done it was labeled 01C6033 on a tiny orange sticker, i presses it down and i heard a click i turn on the ipod and suddenly i caught wifi in my room when the router is on the other side of the house. Now this wasn019t the first time i opened my ipod the first time i opened it i noticed 01C6033 was very wobbly and seemed strange well just push it in and listen for a click, it has circular connectors. 01C6: is located on the upper left corner of the iphone. I %100 sure this is the real solution I belive this happens when you drop the iphone the cable is very delicate. Go ahead try you save yourself a **** of alot of time."+

    Anyone give that any creedance?

    Absolutely infuriating!!!

    It has to do with the account you're using to 'send' email. You'll have to pick one your work likes...

    Did you try the apple trouble shooting guides?

    http://support.apple.com/kb/ts1559

    http://support.apple.com/kb/ts1398

    It you're having problems with your wifi and it isn't fixed with the above solutions (and no, it isn't an iOS4 problem) it means it's hardware. The solder joints in the PCB develop micro-fissures - causing the additional symptom of higher operating temp due to higher circuit resistance. You can pay for apple to fix it, buy an aftermarket motherboard, or fix it yourself http://www.iphonetiquicia.com/repair-iphone-3g-wifi-oven/

    Just don't waste your time complaining to Apple and hoping for a software fix. Ain't gonna happen because software doesn't fix hardware problems.

    Hi all,
    I was having the same lost wifi for the last 1-2 months. Today without any warning the iPhone 3G asked me if I wanted to connect to my MacBook which I had setup to be a wifi network to share files at home. Sure enough, wifi is back! I have recently moved house & have reconfigured all my network & internet services. My conclusion? It is software related. No putting in the freezer or other weird tricks!
    I originally booked an appointment at an Apple Store to do a $250 exchange but got cold feet about paying so much money on old hardware.

    I think messing with network settings, airport, security protocols & anything else you can think of is the way to go.

    I hope this info may help someone else because I know from my own experience just how frustrating this issue is, and how infuriating it is that Apple have totally ignored the problem.
