    i have my iPhone for a week now, it used to connect fine to my home wifi connection but now it doesn't... it does connect quickly and all the settings are the same ( i didn't change anything) but when i open up Safari nothing loads and when i type an address it tells me Safari cant open the page because it could not connect to the server?

    hope some1 helps me!

    thanks in advance guys


    PS: although the wireless signal is full in my iPhone, i dont have any IP address when i check the settings of my connection...all the fields are blank.

    But that is wireless also? Give the suggestion given first and see how that works.

    I haven't had issues with the iPhone not connecting, but sometimes the iPhone accesses the wifi really slow.

    i entered the password again for my network and although that there is a tick next to its name , the edge sign is still up and hasn't been replaced with the blue wifi sign for some reason...

    I have the same problem only its only at my work. Wi-fi works great everywhere else just not at work. I figured I could just do a restore but i've been waiting for the new firmware to come out. I know as soon as I restore and put all of my suff on it an update will be released.

    Mine does the same. I have to enter 'airplane mode', then exit. After that, it works fine.

    If you're not pulling an IP, I would check to see if you have any security settings such as MAC (Machine Access Control) address authentication or WEP/WPA encryption. You can get a signal lock without actually authenticating and the inability to pull an IP address from the wireless router is a strong indication of this.

    I know this is a very old thread, but...

    If you searched on Google and this is what you came up with, (Like me) here is a step by step:

    (iPhone main menu) Tap "Settings"

    then tap "Reset" at the very bottom of the menu.

    Then tap "Reset Network Settings" it will confirm then restart.

    3.0, 3.0.1, or 3.1?

    3.0 and 3.0.1 is notorious for wifi connectivity issues. I had the same problem as you at one time or another.

    A couple of things you can try ..

    1.) Settings > Reset > Reset all Settings
    2.) Hard reset by holding the both the home and power button down.

    simple solution

    Simply go to Network preferrences on your computer and click advanced and then where it says preferred networks click the little pencil icon and re enter the network your I phone connects where it asks you to add the new prefferred net work - even if you can see the network already in preferred networks add it again- no matter what you do to your iphone it wont help until you do that.

    Hey guys, I've been having a similar problem.. I have a 3GS jailbroken with blackrain.. ever since i got it, it always auto connected to my home wifi. then about a week or two ago it just stopped.. But when i go near other "remembered" networks it auto-connects just like it used to.. I havent changed any settings on my iphone or wifi it just all the sudden started to not connect.. under "wifi" in my phone it recognizes "linksys" but when I click on it to connect it displays a window saying "unable to join the network "lynksys"" with a dismiss button.. I reset the network settings like stated above. and rebooted my iphone and modem and router multiple times still resulting in the same problem.. any help?

    Thanks, Chase weston

    nevermind. I got frustrated and ripped the wires out of my modem and router walked off to blow some steam then plugged back in once calmed down let everything re start and now miraculously it connects to my linksys.. thank god. Thanks anyways though
