Incorrect password "wifi" for IPhone 3G

Hi, Im just new here in the forum. I really need help with my Iphone 3G. Before I can connect to wifi but after awhile I can no longer access any wifi, free or secured. When I try to connect to a network, it gives me an error "unable to connect". Then when I upgraded to OS 4.0, there is a new message "incorrect password for (networkname)". My iphone 3G is the only one that cannot connect to our network. The rest of my families' unit (ipods, ipad, laptops) can connect to our router. Can someone shed a light and help troubleshoot. Thanks!

Iphone 3G, iOS 4

On your iPhone go to Settings > General > Reset and select Reset Network Settings. This will delete all wi-fi network settings from your iPhone which will require re-joining every wi-fi network you regularly connect your iPhone with along with re-entering the required password for any password protected network.

Hi Allan,

Had this problem with my 3G. Hardware. I had to reflow the PCB. Rather than using a heat gun I used my oven.

My alternative was paying Apple to fix the motherboard. So the reflow, although a risk, was a simple decision. No matter what I was looking at spending the replacement cost of my phone to fix the problem. I did this instead http://www.iphonetiquicia.com/repair-iphone-3g-wifi-oven/

I don't know if you are familiar with reflowing circuit boards so the tutorial may look crazy. But it's really just a less expensive tool (home oven) than the reflow ovens factories buy. Key is time and stable temp (use a second thermometer to be sure about temp).

Once I did the reflow not only did wifi work but my phone operating temp was cool rather than hot as it was previously. In other words, the reflow reduced the resistance in my solder joints that was previously caused by the micro-fissures. Saved me ~$200.

Hi there,

Did anyone every sort this issue out? I have tried everything, just got two iphone 4's - One connects to my home network fine and the other one does not - However, it connects to other networks fine... so i really dont understand this issue... very strange! I've tried everything:-

1) Mac Filtering
2) Disable passkey
3) Used 128 HEx
4) Reset the iphone back to factory settings
5) Reset Network settings
6) Upgraded to 4.1 OS
7) etc, etc, etc

None of which resolved the issue, i'm at a loss as to how one out of the two iphones can connect and the other cannot... Why can it connect to all other wifi networks but not my own... Could it maybe be a conflict between the two iphones?

If anyone has any ideas it would be much appreciated!

Thanks in advance for your help

Regards

SWM

I'm having the same problem with wifi dropping. It's the 4.1 update. Apple has totally abandoned 3G users, and are forcing us to have to upgrade to iPhone 4 by not considering 3G users in their updates. I now have 'new' bluetooth issues, and the wifi pop up is more annoying than I care to get into.

It's so disappointing. Totally at the mercy of Apple. Thanks, Steve Jobs.
