Iphone will not connect to Internet without WIFI connection

My iphone will not connect to the internet without a wifi connection.
I have restored the settings many times. But i still have this problem.
I get a message on safari which says 'could not activate celluar data network'
what do i do?

If you have restored your iPhone with iTunes from your iPhone's backup and as a new iPhone or not from your iPhone's backup with no change, have you contacted O2? Your line may need to be reset by O2, which will involve turning your iPhone off whole O2 does the reset at the server, or possibly there is a problem with your SIM card.

Many ppl Not being able to connect to internet although wifi connected.

Other forums are recieving many posts a day on this issue, and as I understand it Apple are recieving alot of calls on this issue:
Description:
Connection to an encrypted wifi network seems succesfull, however when attempting to reach the internet Safari throws up an error - The server could not be contacted - or words to that effect. None of the Internet requiring Apps work although the wifi signal indicator shows signal indicating connection.
When you click on the little blue arrow to the right of the network connection you are connected to, in "Settings > Wifi" you see a self assigned IP Address starting 169.254 and a subnet mask 255.255.0.0, with possibly no DNS if you haven´t manually entered it and no gateway.
Peculiarities:
1 Problem is widespread, not tied to specific make of router or AP, also it happens to most people on more than one AP or router
2 People with this problem are assigned a 169.254 IP address, Indicating no DCHP lease of an IP address
3 Ive ran a packet capture using wireshark and Air PCAP and seen no packets for a DCHP request.... wierd.. it looks like its not even requesting an IP address..
4 Only seems to happen on networks using some kind of encryption be it WEP, WPA, etc...
5 Although theres bars in the wifi icon that indicate a connection, it cannot be connected to the network, just try and ping your device when its supposedly connected, look at the IP.. it cant be on the network.
6 Even if you manually imput the IP address, sub mask, and gateway IP it still wont work.
7 People with Iphones seem to be able to circumvent this issue or a similar issue by manually selecting the encryption method or changing the encryption method on the router.
8 Issue observerd in varied firmware versions
Possible Conclusions:
1 The Ipod is selecting the wrong kind of encryption when the enter password dialog box comes up? OR bad key negotiation between IPOD and Router.
Although scenario 1 shouldnt be the case as WPA and WPA2 have to be a certian length etc..
Note: I have tried connecting to the network by manually entering the network details and encryption under Settings > Wifi > Other and still no luck..
Questions:
Could someone with this issue confirm 1 wheather they are using WEP encryption. 2 weather it works on a non secure router or AP. 3 weather they are imputting the full HEX key or a passphrase?
I get the feeling if you use the full hex key it may work, ive seen posts around about having to make it recognise that you are using HEX by appending a $ sign to the start of the key.. although i dont know how true this is.
I have no access to the router that dosent work for me.. so cant do tests as my home one works on all encryption methods, but ive seen about 5 Routers and AP´s so far that wont work.. all using WEP..
NOTE
On one specific AP I connect with my Ipod and get no IP from DHCP so no internet, yet my colleague sitting right next to me with an iPhone gets a DHCP assigned IP and is surfing away no probs! it even automatically connects, and im very jealous..!
Anyone got any ideas?

This happened to my ipod touch recently, on my own network--it worked the night before, but not the next morning (even though I had a full wireless connection on the touch). I had to 'forget' that network and re-add it (including WEP) and then I was able to re-connect. no idea why this occured, but that did the trick. So far, I've only had to do that once...

What make, model and version router do you have?
Is MAC address filtering turned ON in your router?
Do you have a limit on the number of connections set in your router?
What type of security are you using, i,e, WEP, WPA, WPA2?
Have you tried restarting your router? (remove power for 30 seconds and restart)
Does your iPad 2 work on any other networks? Starbucks, Borders, etc

Wifi signal is on, in settings it says its connected, but when attempts at loading anything occur, nothing loads. Iphone works on the ad hoc network, won't be able to get to a wifi spot for her to surf around with for a while

Does the iOS device connect to other networks?
Does the iOS device see the network?
Any error messages?
Do other devices now connect?
Did the iOS device connect before?
Try the following to rule out a software problem:
- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Power off and then back on the router (or what yo are connecting to)
- Reset network settings: Settings>General>Reset>Reset Network Settings
- iOS: Troubleshooting Wi-Fi networks and connections
- Wi-Fi: Unable to connect to an 802.11n Wi-Fi network
- iOS: Recommended settings for Wi-Fi routers and access points
- Restore from backup. See:
iOS: How to back up
- Restore to factory settings/new iOS device.
If still problem make an appointment at the Genius Bar of an Apple store since it appears you have a hardware problem.

How to i connect to internet without wifi on my macbook air

Hi
i have a MacBook Air and i am visiting with my parents who do not have WiFi ....
how can i connect ?
as you know, there is no Ethernet Port on the MacBook Air
can i do this remotely through their PCs ?
thanks

If they have PCs with wi-fi capability. Most/all Windows laptops will but many Windows desktops do not. The following instructions may help (both are for Windows 7 so you may have to search if that isn't what they have):

Another option is an ethernet adapter if you have time to obtain one:

HT204135 My computer is connected to my Epson printer but for some reason it will not print, it has a wifi connection but is not connecting for some reason, what can I do to resolve this matter?.

My printer is not connecting with my computer via Wi-Fi, want can I do to fix this problem?.

Exactly what is going on with my Epson XP 810. I will reset my modem and it will print one or two pages and then say "Searching for printer" and it will never find it unless I reset the modem. Was working fine last week so I don't know what changed.

ITunes will not open (with or without nano connected)

Please help me, I'm a newbie...
The root of the problem was my computer "not being auterised to play music" (even though it was), that I'd purchased via a £15 music card, when using the help suggestions on here, I fixed THAT problem but unfortunately it created a new one: "iTunes has encountered a problem and needs to close"
Using many different help suggestions on here, I have now done the following:
- Upgraded iTunes and Quicktime to their latest versions (that had no effect)
- Deleted the following folder: c:\Documents and Setting\Application Data\Apple Computer\iTunes\SC Info (after upgrading), no effect.
- I deleted and re-installed both iTunes and Quicktime (also, not effect)
- Tried istalling free (AVG) anti-spyware, running system scan and "disposing of" problems...
These were all suggestions I found on here but I still cannot open iTunes..
I've been listening to the same 90 tracks on random/repeat for over a month now and am going a bit mad..!
Please help me!
Thanks
PS I have Norton 2007 if that's of use..
Windows XP

Hi macnfries,
Have you tried deleting all iTunesSetup.exe installers off your computer, and then downloading the latest version of iTunes (version 7.2.0.35, as opposed to 7.2.0.34)?
Go to this page to downlad the latest version of iTunes:
Download iTunes - 7.2.0.35
Any success with that?

About the only other way I can think of is to have a computer with you or use one there, if you can put iTunes on it and download all your new stuff to the computer, then sync your iPad to that computer.
In switching computers you will lose previous content, but, as I understand it anyway, downloaded content will be the same as long as the same apple ID is used.

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.

TS1398 After leaving a wi-fi connection my iphone will not automatically connect to the internet via the 3G network unless I turn it off and then on again. Is there a setting that can be changed to overcome this issue?

After leaving a wi-fi connection my iphone will not automatically connect to the internet using a mobile 3G network unless I turn my phone off and then back on again. Is there a setting that can be changed to overcome this?

Then I'm at a loss. Mine has switched automatically from the start, favoring Wi-Fi, any of its registered networks, whenever available. Only thing I can think of is trying a Force Restart and see if that clears things up: hold down Home and Sleep till the screen goes black and a white Apple logo pops up. Release and allow it to restart.
May be similar, when I got the i5 about 16 months ago, the local carrier was starting to roll out 4G service. The phone would regularly lose all carrier connection, voice and data. Haphazardly would reconnect when it felt like it afterwards. Initially did the Off/On dance to speed things up, but discovered that using Airplane Mode would do the same without the lengthier power cycle. After awhile, the carrier 'fessed they were having capacity issues and later the problem went away. So yours too may also be a carrier issue.

My iPhone 4S connects to the internet without wifi?

Trying to share my iPhone's internet connection wit my other apple devices, but I cannot because the personal hotspot option is not there. Does it have anything to with the following: My iPhone, inside or outside the house, connects to he internet without being connected to a wifi network. Is this why? If not, how can I connect my devices?

Can both MacBook Pros see other Wi-Fis, just not yours? What is the make & model of your wireless router/gateway device? If this device supports Ethernet connections, can both MBPs gain network/Internet access this way?

I recently changed my wifi password at home and now my iphone will not connect. It will not ask me for a password just says will not connect to network. Advice on how to get iphone to ask network password for wifi?

I recently changed my wifi password at home and now my iphone will not connect. It will not ask me for a password just says will not connect to network. Advice on how to get iphone to ask network password for wifi?

First, try tapping on the network in the Wi-Fi settings and then tap "forget this network". Then reselect the network in the main Wi-Fi settings screen and see if will then ask for a password. If not, try resetting the Network Settings in the General -> Reset section and then reconnecting to your W-iFi.
Hope this helps.
