Hey all. I had an iPhone 3gs with iOS 4 installed, and it was able to connect to my wifi network.

When I bought the iPhone 4, it can no longer connect to my wifi.

For reference, MAC filtering is NOT on.

Also, I am NOT broadcasting the SSID of my wifi network.

In short, the iPhone 3gs was able to connect regardless of the network name not broadcasting, whereas the iPhone 4 simply states it cannot find my network.

Any tips?

    It seems like an issue with how you set up your WLAN settings on either your iPhone, your wireless router or both. I also don't broadcast my WLAN and because of this had to ensure the first time entering the data into the iPhone to use the correct alphanumeric password which uses upper and lower case otherwise it won't connect.

    I have the exact problem. My iPhone 2G was able to connect my wifi.

    But now my iPhone4 cant see any network. And my sister's iPhone4 can find networks.

    Anything?

    You say you're not broadcasting the SSID of your home network (no real reason not to since anyone with Netstumbler or the ability to read a wireless packet capture can find your SSID in seconds)... did you manually add in your home wireless network on the iPhone 4?

    If you did and you're still having problems, have you picked the correct security method, spelled the SSID correctly, and entered in the correct pre-shared key or whatever you're using to secure your wireless network?

    Yes, the Network name, security type, and password are all correct. It still doesn't work.

    I had the same problem, also with iphone 3G, the phone saw the signal, but would not connect. if you can see in WIFI settings the IP address and the numbers below it, substitute your DNS for 208.67.220.220, or maybe 208.67.222.222. See how that works.
