IPhone won't connect to ANY wi-fi network.

I bought a brand new iPhone 3g 16gb after my old one got ran over. My problem is that it will not connect to any wifi network at all. When I try to connect it says Unable to join the network "ssid here". I have disabled all security on my router, and even forced it into b and g mode only. I have also did the phone reset and network reset in the general options. Still no luck. I am running the latest 2.2.1 firmware. The phone is only 3 days old. Should I take it back or is there a fix for this?

Couple troubleshooting tasks:
1. Does anything else connect to your wireless net?
2. I would go ahead and use wpa security and make sure you have the passwork correcty spelled.
3. What router are you using and is its firmware up to date
4. Does your phone connect to anyone elses wi-fi
5. Does wi-finder indicate you have adequate signal to connect
6. How many connections are you using on your net
Let us know the answers to these questions and my theory is that if you phone can 'see' the ssid on your net we can get it to connect..

IPhone Will Not Connect to ANY Wi-Fi Networks

I have an Airport at home that is completely open (no password, we live in the country) which my new iPhone can see in it's Wi-Fi Networks window, but when I try to connect it says, "Unable to join the network." So, I took the iPhone to the office where it can pick up 8 local Wi-Fi connections, 3 of which are open and for each one I still get the same errror. Finally, I attempted to connect to our office Wi-Fi, which is password protected, but same error.
I have read through several forums now and found similar posts but none have answers. And it makes no sense still that my home Wi-Fi, using an Apple Airport (to which I am currently surfing in order to write this post) will not let me join -- even while standing a few feet away.
1. I have already reset the Airport
2. I have tried both with and without WEP security turned on
3. I do have a Wi-Fi address assigned in my General > About prefs on the iPhone
Can someone please help?!?!

Just bought the phone today, hooked up to my personal WiFi, no apparent problems. Later on, I noticed that it had reverted to EDGE. After research, I found all the usual suspects - reboot router & phone, Airplane Mode, manually enter Subnet Mask, etc.. I could consistently connect, but then would get booted off as soon as I tried to do something online. Finally, I updated to 1.0.2. Now, it kicks me out, just as dkelly is experiencing.
How has the Software Update made things worse on this front?

My phone (4s) won't connect to any wifi since the ios7.0.2 upgrade

Since updating to 7.0.2 my iphone won't connect to any wifi network. I've done all the steps in help from forgetting the network to a full software reset and setting the phone up as a new device. Vodafone assured me that the next upgrade would correct the problem, it hasn't! They are now refusing to honour the warranty because the phone is now beyond its warranty ( due to waiting for the upgrade ).
I've Been assured by the tech guys at the local apple store that the problem is not hardware because the phone can see the networks.
Anyone know if apple have any plans to fix the wifi problem any if so when ?

Yes I've already restored the phone, once unconnected and again via iTunes, both times I set it up as a new phone and didn't restore the data or settings, I also deleted the iCloud account first so it couldn't backup from the cloud. The fault was exactly the same each time.
As far as the warranty I'm sick of arguing with Vodafone, the phone was in warranty when I reported the fault so you would think that they would honor the warranty, however I'm told by Vodafone that when I asked for a repair the warranty had expired.
Apple tell you all about European consumer law which provides additional protection, when you look into this it is advisory only and has no enforcement powers ( I've checked this with the ecl website).
Basically I'm stuck between two multinational companies that appear not to give a s*** about their customers!

My iPhone 5 won't connect to any bluetooth or wifi, What do I do?

My iPhone 5 won't connect to any bluetooth or wifi, I was going to back it up and restore it but it won't back up to my macbook pro. I'm running Lion 10.7.5. as of right now. I don't know why it stopped working, my itunes is up to date and I cannot back it up to there either. What can I do?

See if this helps

Iphone 4s won't connect to ANY wifi networks

I can turn on wifi, see networks in my area but it won't connect to any. Any suggestions?

Follow these steps to resolve the issue:
Verify that airplane mode is off by tapping Settings > Airplane Mode.
Reset the network settings by tapping Settings > General > Reset > Reset Network Settings.
Note: This will reset all network settings, including Bluetooth pairing records, Wi-Fi passwords, VPN, and APN settings.

IP Address Is Duplicate and iPhone Won't Connect

Everything was working for last 2+ years, then my modem died yesterday. I replaced it, but can't get back to where I was. I ended up restoring network to factory settings and then doing connection.
I have AT&T DSL service. When setting up the connection with my AirPort Extreme, have Ethernet with Bridge Mode. I receive message that "another device on the network is using your computers IP address." I didn't have this issue when setting up 2+ years ago. So, I manually changed the IP address, but this caused a message about DNS not being correct, which I ignored, because this at least gave me access to Internet, and I didn't have to "borrow" from one of my neighbors unprotected networks. I have implemented WPA2 security (which I had prior to this also).
Issues I now have are:
- iPhone won't connect, and it did before all this
- HP Photosmart printer (which is wireless) also won't connect, as it did before
I assume that all my issues are from not configuring correctly, and that it revolves around the IP address conflict.
Any assistance?

You need to do a Factory Default Reset on the AirPort Extreme (AEBS) to clear out all the old settings and IP conflicts.
Pull the power plug on the AEBS
Hold in the reset button and while you continue to hold it in, plug the power back in to the AEBS
Release the reset button after 10 seconds.
Open AirPort UTility and set it up again to Create a wireless network.
It's easiest to click Continue and follow the guided setup.
Ignore the Double NAT message when/if it appears.
I know this works. I have the exact same equipment on my desk now.

IPhone won't connect to wifi at all!! Please help.

I have an iPhone 4 and I don't use it as a phone any more but I do use it for downloading songs and stuff of wifi, kinda like an iPod touch but I dropped it in water(not the first time I have done this) and as usual it will come back alive after drying but this time the wifi says no wifi and it is colored light gray.everything els is normal about the phone except I can't get Internet via wifi. Can someone tell me if there is another way to access the Internet with this device or how to fix the wifi? Oh and one more thing, when I go to general and press about I see that the wifi address says N/A so I don't know if I can just get a new address or what.

"followed all directions"
so you followed ALL the steps described in these articles?

If so, since it states:
If someone else set up your network, ask them for help. If you’re using a network at a company, school, hotel, store, or other free Wi-Fi location, find an employee for assistance.
If you're connected to a Wi-Fi network but you can’t get online, try to use your Wi-Fi network on other devices. If you can’t get online using your other devices, there might be a service outage. Call your cable company or internet provider for help.
Try connecting to a Wi-Fi network in a different location. If your device can connect, you’ll need to get help with your Wi-Fi network. If it can’t connect to any Wi-Fi networks, contact Apple.
Update your Wi-Fi router with the latest firmware and make sure the router supports your Apple product. For more information, contact the manufacturer of your router.
Who set the wifi?
what other devices did you try?
what did the internet provider say?
did you try different wifi locations?
Thanks for taking more time to post your problem and for using Apple Support Communies

Iphone won't connect to internet or send messages

My iPhone won't connect to the internet at all nor will it even send SMS messages. I've already tried resetting the network settings and that did not work. Are there any other solutions out there for this problem?
Thank you!

Your right....I can't believe it. I disconnected my phone from my wifi. Shut it down and turned it back on. Sent myself an email message and on the 3G network phone picked up message immediately.
Now I am seeing if the 30 minute rule you had still applies here.
What a mess...but I gotta say, Love the phone, better battery, amazing screen, faster....just a few things that are really important going wrong!

Iphone won't connect to wifi

My iphone won't connect to my home wifi. It say's connected but when i try and go online it say's unable to connect. I've tried forgetting the network, turning wifi off and on. The ip address is ok and my laptop connects ok.
Has anyone got any ideas about how i can fix it?

I am having the same issues as GirlyGirl. Every other day or so my iPhone 3GS won't connect to wifi. Before I was showing the wifi signal as if it were attached but I couldn't surf Safari. Now even though under the wifi settings it shows I'm connected, I don't get the wifi fan showing I'm connected. I've done the following:
Renewed lease
Forgotten network
Reset Network Settings
Reboot my iPhone
Two days ago when I rebooted the router and Reset Network Settings it started working correctly.
I've been working with my internet provider, they tell me my firmware on my 2wire is up to date & the issue is definitely with my iPhone.
Security Settings: WPA-PSK (TKIP) and WPA2-PSK (AES)
My iPhone is attaching to the 169.x IP Address and the Subnet is 255.255.0.0. The router, DNS and Search Domains are blank.
Also to note, I changed the name of my device through the gateway router so I could identify it more easily. As of today it had defaulted back to the old name which is the ip address. Even if I don't change anything it isn't keeping those settings.
Other than restarting my router and taking everything down for 15 minutes each time, what else can I try?

My won't connect to any computer

My won't connect to any computer, it's up to date with IOS 6.1.3 and i've used mulitple ipod charging cables but nothing works, it only charged when it's completely flat too, then it turns on and stops charging, goes flat and charges again, I also reset it and it didn't help, and now i've lost all my photos because i can't connect to a computer to restore my back up, someone please help, also the only way it full charges is if i leave it in sleep mode, it doesn't say it's charging but later on it will have full bettery

Try:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode
How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- Try on another computer
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.
Apple Retail Store - Genius Bar
also
Not Charge
- See:
iPod touch: Hardware troubleshooting
- Try another cable. Some 5G iPods were shipped with Lightning cable that were either initially defective or failed after short use.
- Try another charging source
- Inspect the dock connector on the iPod for bent or missing contacts, foreign material, corroded contacts, broken, missing or cracked plastic.
- Make an appointment at the Genus Bar of an Apple store.

I've not upgraded to IOS 6 on my ipad, and my Verizon hotspot on my Iphone won't connect to my Ipad
