Try calling Apple support: if you just purchased your iPhone they should be able to talk you through it: 1-800-275-2273
Your iPhone should pick up the ip address of the wireless router. If your router has a password or encryption, the iPhone will ask you automatically for the password.
I just bought a Belkin N Wireless Router today and set it up for my 2 PC's & when I went to get my iPhone it had already registered the Belkin wi-fi and I could use wifi instantly without any configuration or problems. I went into airplane mode just to make sure and I could access safari, email, iTunes and download apps at very good speeds. At last now I have wifi! The Belkin router just worked out of the box for me. Of course I knew to go into my modem's browser address and turn on NAT. Everything just worked and I never even used the cd software included to set it up. No passwords or errors or problems. Terrific!
If this helps anyone… I had the problem that my iPhone didn’t detect my wi-fi router at home, and after I entered my router (192.168.2.1) I started playing around changing settings made 2 changes:
-Changed the 802.11e QoS configuration (whatever that means) from off to on.
-Replaced an hyphened character (á) in the SSID for a normal character (a).
After doing this 2 steps clicked on aplly, waited 25 seconds for it to restart and now my iPhone detect my home wifi connection.
I don’t know which one of this steps is the one, but is 2 in the morning and I’m not gonna look into it now.
Hope this helps anyone.
Hi I'm actually having that same problem except mine is an unlock iPhone but I have to say the wifi used to work at first then it just stop working recently,like when I click on it it would say searching for network and just stay there.it never shows no network.any suggestion please
The iPhone 3G has many wifi issues on a hand-Full of the phones the wifi chip could get over heated and therefore break etc . all i can recommend you to do is go on your iPhone into settings>General>Reset>Reset Network Settings .....and see if that works . also is the wifi connection your personal connection or is it one you randomly found?
Yes, I have also tried syncing to iTunes as a new phone, doing a hard reset. I don't know what else to do. I called Apple and they said, I can get a new one for $199.00 I don't think it's worth it since the iPhone 5 is coming soon...
