iPad 2 - Problem with 3G connection

Maybe you can try to write the APN settings and then sync with iTunes, it worked for me.

Strange, maybe you must contact your mobile provider about it?

I have the same problem (well, similar). UK iPad 2 32Gb Wifi+3G.

Normally I have the 3G turned off unless I need it as when i'm at home it uses Wifi.

However, if I disable Wifi and then enable 3G, although the 3G comes up, the IP connection doesn't. I have to restart the iPad with the wifi disabled and 3G enabled to get the 3G to work.

I would suggest the issue is with their implementation of the IP stack and it not clearing out routes properly (or letting go of DHCP possibly) if you enable Cellular data whilst the iPad is on. The IP stack doesn't seem to be routing out through the 3G in that case and therefore nothing thinks it can see the Internet?

The only way we can conclusively test that is for someone to jailbreak the device to get to the command line and take a snapshot of the routing tables for each configuration. That will show where the error is.

But the simple answer is you're not alone, and it'll need Apple to fix it (it can't be carrier specific as I'm on Orange Uk and you're not!)

Hi - I suggest you all read this thread, because iPad 1 generation or iPad 2 - still the same problem - it's for sure related to software issue - no doubt about it, because it has been reported from all over the world - only Apple does not seem to accept the fact. Noone had any problems before upgrading from 4.2 and to 4.3 release software. Apple even made an 4.3.1 without solving this massive problem! My best advice to people having a iPad first generastion - stick to the 4.2 software - it works perfectly.
Shame on Apple for not fixing this issue. And shame on Apple for not letting us go back to working software untill problems are solved!

But why you disable WiFi? I never disable WiFi, I turn on 3G by turning off on my iPad en then use the PIN for 3G.

That's true. It's not fun to know that this problem has not been solved. At least it's not my device alone. Hopefully if we call apple support snuff they will have to address it.

Alrite, got a temporary relief from the tooth ache of my 3G doesnt work. I called app support, they advised to reset all network settings and it connected beautifully
