Apple Releases WiFi Support Document

Apple Today, Apple released a document to help iPhone and iPod Touch owners who are having Wi-Fi issues. Below are the Symptoms and some Fixes. You can see the original document on Apple’s website HERE.

Syptoms

    • iPhone or iPod touch appear to be connected to a Wi-Fi network but cannot use Wi-Fi for checking email, surfing the Internet, or other data transactions.

    • On the device, when you tap Settings > Wi-Fi and then tap next to the network, no values or entries for IP Address, Subnet Mask, Router, or DNS appear.

    • The device shows no Wi-Fi address (Tap Settings > General > About and scroll down to Wi-Fi Address).

This can happen if, during the initial setup of the iPhone or iPod touch, no Wi-Fi address was registered. So while the device can attach to different Wi-Fi networks, it will not be able to retrieve an IP address because the Wi-Fi router doesn’t see a Wi-Fi address from the device.



Resolution

First, sync your iPhone or iPod touch to iTunes in order to backup your user info, Contacts, Calendar, and other data. Then, try the following steps in order.

Step One
On the device, tap Settings > General > Reset > Reset Network Settings. Check to see if the device now displays the Wi-Fi address (tap Settings > General > About and scroll down to Wi-Fi Address). If there is a Wi-Fi Address, then you’re done with these steps and can resync your settings and your media using iTunes.

If there’s still no Wi-Fi Address, then continue to Step Two.

Step Two
On the device, tap Settings > General > Reset > Erase All Content and Settings. Check to see if the device now displays the Wi-Fi address (tap Settings > General > About and scroll down to Wi-Fi Address). If there is a Wi-Fi Address, then you’re done with these steps and can resync your settings and your media using iTunes.

If there’s still no Wi-Fi Address, then continue to Step Three.

Step Three
    1. Restore the iPhone or iPod touch software (this erases all data on the device) using iTunes (see article 305744 for additional assistance).
    2. After the restore is complete, sync your previous settings (mail settings, text messages, notes, call history, contact favorites, etc.).
    3. Now verify if your device shows a Wi-Fi address (tap Settings > General > About and scroll down to Wi-Fi Address).

If there is a Wi-Fi address, then you’re done with these steps. If there is no Wi-Fi address, then continue to Step Four.

Step Four
If there is no Wi-Fi address listed after doing the above steps, then your iPhone or iPod touch may need to be repaired. See the iPhone Service FAQ or iPod Service FAQ for additional service information.

Note: If the device shows an address in the Wi-Fi Address field and you are still having issues using Wi-Fi, refer to article 305715 for additional Wi-Fi troubleshooting tips.

  1. I thought jailbreaking my phone was the issue. Did a restore and did this before this came out. 3GS has a very wifi hardware. my 2G is connected ok but the 3GS show weak signal and won’t connect to the internet.

    I did a restore yesterday a little better but still very frustrating.

  2. I had an issue which caused the 3GS to show only a 3G connection instead of my home wifi network. I tried airplane mode, turning off and then back on wifi and even rebooted the 3GS. Those attempts made no difference.

    I use static IP addresses here at home and merely changed the IP address to another one. Bam, it works and has worked ever since. Sharing this just in case others have the same issue. Thanks for sharing the Apple Doc.

  3. I had this issue and followed the what apple recommended.
    BEWARE!!!!
    After step 2 my phone never recovered. It went through the process (about 1 hour) and then reset it self. It kept resetting it self for a few hours!!!! The logo woutd come up for a while then the screen would go black then back to the logo.

    I was able to enter into DFU and restore the phone back to 2.2.1 but the WIFI is still not working.

    • iPhone 3GS says:

      my phone is stuck like u said and i cant get into dfu mode how did you do it?!?!?

    • Have the USB cable plugged in

      hold down the power and home button for about 30 seconds.

      Release the two

      Press and hold the power button.

      When the apple logo comes up hold down home button with the power for about 10 seconds.

      When the apple logo goes away release the power button.

      Keep holding the home til itunes recognizes the phone.

      I then had to do a restore of the release 3.0 (not my custom)

      It is very important to not ho through a usb hub.

      I then ran redsnoe to bring me back.

      Going back to 2.2.1 did not help. Apple was willing to replace my 4GB phone for 199 … I’ll wait for the 3.1 to come out to fix this.

  4. One issue I had with my wifi but I don’t know if it’s an apple problem or jailbreak was that I could not use my wifi when I was using my Bluetooth. It’s not that of a big deal to me but was wondering if anyone else had that problem. I’m on a 2G iPhone.

  5. iPhone 3GS says:

    My iphone 3GS has been connecting with the wifi but then after 5 mins of it working great, I’ll try to go to a website or the App Store and it wont load. So i have to go turn off wifi and turn back on so that it will work again. And when i did step one it made my iphone go into safe mode. and wifi is still the same as before!
