I received my iPhone 3G about a week ago, and the wifi seemed to work fine until last night. Suddenly it would only show the "E" or "3G" logo even though I was supposed to be connected to wifi. I went to settings and it says under wifi that it is "not connected" and it will not show my network. When I try searching for my network, it says "cannot find belkin54g".

However, one time it did work, but when it connected to belkin54g, it only lasted a few seconds and would switch back to edge and 3G. I have not been able to find or even connect to it since.

I checked my routers page, and I do NOT have MAC filtering enabled, and I do NOT use any type of security or password. It is an open wifi spot that does not use a password, so for security on the iPhone I select "none".

I have reset my iphone, I have reset network settings, I have reset the router, and still I can not get wifi back on my iphone.

Could this be the 2.2 software? Everything was working fine, I have no idea what happened.

    Hi jmsn2393,

    Try syncing and backing up the content on your iPhone. then restore the iPhone and set it up as a new phone.

    You can sync the content from the iPhone using iTunes. This article: http://support.apple.com/kb/HT1766 will provide details about the backups that iTunes can create for the iPhone.

    This article: http://docs.info.apple.com/article.html?artnum=305744 will walk you through restoring the iPhone.

    -Jason

    Thanks Jason, but I tried that, and it didn't work.

    I still can not find the wifi network, nor connect to it.

    Update: After leaving my iPhone on standby for a night, it reconnected to my router for 5 minutes. Then, after about 5 minutes, it went back to Edge. The IP address starts with 192, and everything appears to be fine, except for the fact that it won't stay on wifi for longer than 30 seconds now, even when I am 2 feet from the router.

    Surely this is not a wifi hardware issue, this has to be a software glitch everyone seems to be posting about.

    I have tried a full restore and everything like that on mine eg clear network settings etc. In the end spoke to Apple - went thru a whole load more stuff with their tech guy...no joy. Now it is back with Apple (via O2) and I am awaiting a repair or new phone. There is a 12 month manufacturers warranty so you are covered - but going back to my old Nokia has not been fun - no Wifi, iTunes or apps!

    I'm experiencing the same problem as you are. In addition, the Bluetooth isn't working as well. Have you managed to rectify the problem?
