IPhone 3GS not connecting to WiFi

I own 2 iPhone 3GS that have been connected to my WiFi (Broadcom 802.11b/g WLAN) since I purchased the phones in July 2010. 4 days ago, one of the phones stopped connecting. It recognized the network, and asked for my password. When I input the correct password, it comes back with 'incorrect password'. After repeating several times, just to make sure it wasn't a typo, I disconnected wifi from my other phone, repeated the above steps, and it connected just fine.
What the $%^& is up with my phone? P.S. Have not updated iOS to 4.3... still at 4.2.x
Thanks in advance for the assistance!

I am having the same problem. We replaced our Airport Extreme on March 17 and then this started. The computers on our network connect fine. The 3g iPhones and the iPod touches do not. I have reset the airport, reset the network settings on the phones, adjusted the router setting to WPA2, and it still does not work. There seem to be quite a few people having this problem. Is Apple doing anything about this?

my iphone will not connect to wifi no matter what HELP

Have you tryed to restore the iPhone too ?
Restore the phone in iTunes using a backup, and if needed as a new iPhone, without using a backup. However, the greyed out WiFi is often due to a hardware failure requiring replacement of the phone.

At the very least, I recommend you restart your router, (your internet box).
More detail on your problem is needed - are you in a submarine? On the moon? On a tropical island?
You can help yourself by providing as much info as you can about your present situation - what kind of router do you have? Have you moved it? DId you update it? Did you do anything to change your setup, and if you did, what?

Iphone 5s not connecting to wifi

Hello,
I bought new iphone 5s and when tried to connect to wifi for initial setup it doesn't connect to the network.
But my other iphone 4s and ipad are connecting to this wifi and there is no issues on the network.
I tried to reset the network setting and even I done complete reset also. But still my new iphone 5s is not connecting to wifi.
Can any one provide me an solution for this issue. Thanks.

MAC address filtering is not turned on and it is not entered into the router.
There is no limit set on the number of connections.
The password which I entered is correct.
Yes, tried restarting the router by removing power for 5 mins.
I could able to connect my other apple devices into this wifi router. Only the new device is not connecting to wifi.
My new deivce has iOS 7.0.6. May be if I upgrade to iOS 7.1.1, this will work?

Resolution
Follow these steps to resolve the issue:
Restart your iOS device.
Make sure that airplane mode is off by tapping Settings > Airplane Mode.
Reset the network settings by tapping Settings > General > Reset > Reset Network Settings.
This will reset all network settings, including Bluetooth pairing records, Wi-Fi passwords, VPN, and APN settings.
Make sure that your device is using the latest software. To do so, connect your device to your computer and check for updates in iTunes.
If you still can't turn Wi-Fi on, please contact Apple for support and service options. If you can turn Wi-Fi on but are experiencing other issues with Wi-Fi, please see these steps.
Thanks for reaching out to Apple Support Communities.

IPhone will not connect to WiFi

My iPhone will not locate my wifi even though all other devices connect to it no problem. It's like the network isn't even there.
This happens every couple of weeks and I have to go to settings -> general -> reset -> reset network settings and then it works again. I guess this is a bug having to do with too many stored networks? Why doesn't apple fix it?
Today the usual solution didn't work and neither a hard reset.
How can I fix this? Thanks.

If no change after resetting network settings, try restoring your iPhone as a new iPhone or not from your iPhone's backup.
If no change after doing this, more than likely there is a hardware failure. The iPhone includes a one year warranty.

Hi Alisadat,
Welcome to the Support Communities!
It sounds like you have intermittent Wi-Fi connection if you were able to update your iOS to 7.0.2?
Although you have tried some troubleshooting steps, I would suggest following the guide below in order to attempt to resolve this issue:
iOS: Troubleshooting Wi-Fi networks and connections
http://support.apple.com/kb/TS1398?viewlocale=en_US
Reset network settings by tapping Settings > General > Reset > Reset Network Settings.
Note: This will reset all network settings including
previously connected Wi-Fi networks and passwords

hi. Can someone please help me how to update the iOS version of my iphone 3gs. Thankyou. Software update is not available in settings.

Over the air updating of iOS needs iOS 5 or later so unless you have iOS 5 or later you will not see updating in setting

IPhone 3gs not Connecting to Linksys E900

Hi,
We have 3 iphones in our house and all of them are iPhone 3gs. We also have a Macbook and an iPad-2. I got a new router installed yesterday - Cisco Linksys E900. After the internet connection service provider has configured the router, we are able to access internet on Macbook and also iPad-2. But we are unable to access internet/wifi through our phones.
We have tried:
1. Resetting Network Settings.
2. Changing the Wifi settings to manual and choosing a different channel (tried Channel# 1, Channel# 6 and Channel# 11).
It is very surprising and frustrating that iPad is able to access Wifi but iPhones are not able to.
It is detecting Wifi but when I tap on it, it says "unable to connect to the network". When I tried to check IP address etc on iPhone, it is all blank.
I am sure this has got something to do with iPhone and Router configuration only. I tried reaching out to Apple and also to our service provider but they all threw their hands up, puzzled.
Can anyone please share how do I resolve this.

iPhone not recognized in iTunes for Windows

IPhone 3GS not connecting with iTunes 10.1.1.4

Hey all,
I'm having a rather peculiar problem. Recently I had to do a factory restore of my HP Pavilion dv6, and I proceeded to download the latest version of iTunes. Whenever I try to sync my iPhone 3GS, it doesn't show up. Yes, I've tried everything. Reinstalling, resetting, restarting, msconfig settings and whatnot, and nothing works. It appears in Windows 7 just fine, with the autoplay box popping up every time I connect it and Windows Explorer noting it down as a digital camera. iTunes will not read the device.
Every time iTunes connects, however, a message box appears saying that it cannot burn CD/DVDs due to the fact that the registry settings used by iTunes for doing so is missing, and caused by a possibility of other CD/DVD burners already installed.
So I removed all the preinstalled junk that HP threw on my comp, and there are no CD/DVD burners on my computer now. Yet the dialog box is still the same.
So are the two related? Are these registry settings that I'm missing preventing me from syncing my iPhone? And if so, how do I fix it? I'm very tech-savvy so complicated instructions will not be a problem (hopefully!). Cheers.

Why is my iphone 4 not connecting to wifi

So I have had my Iphone 4 for two years and it has been great. Last week i bought a new computer and when we hooked it up my phone started acting up to the wifi and says unable to join. I dont know if the new compter has anything to do with it or not. My fiances iphone 5 still connects. i call my phone company and they reset our internet and i can then join on but then it kicks me right back off. I just want it fixed!! lol

Sounds too coincidental to have both phones go bad at once on the same day.
It could still be your router, even if you have reset it.
Have you tried connecting to another WIFI network, like a public WIFI or neighbor's?

Iphone 4 not connecting to wifi

All,
Suddenly my iphone 4 will not connect to my home wifi. There are 4 other devices currently connected that do not have issues (including my iPad, iMac and wife's iPhone 4.) The router logs show the attempt to connect "DHCP received a request from...)" but the phone will not connect. I have done the troubleshooting check list: http://support.apple.com/kb/TS1398?viewlocale=en_US&locale=en_US
Any other suggestions?
Thanks.

My Iphone will not connect to WIFI

My iphone has worked fine with no problems connecting to the internet through WIFI. Recently my home network would not connect. the network shows up on the wifi search I click connect I type in the Network password and it says incorrect password.
I checked my router settings and even removed the WEP security and changed the network to none, so even when i try and connect it says...unable to connect to this network. I have also tried to connect to other wifi networks at different locations and they also don't work.
I have restored my iphone and still no change, I have also restored the network settings and still nothing...
can anyone help?

The normal way to approach this on home networks is to
1) Reboot the router by pulling out the power cord
2) reset the iPhone's network settings - Settings > General > Reset > Reset Network Settings
3) When your iPhone restarts, tap Settings > WiFi > Other and re-enter your network name, security, and network password.
If you removed security on your router, reboot it before you try and connect to it. If you get it working, use WPA2 when you put security back on your network. WEP is highly vulnerable to cracking.
