iPhone 4 cannot connect to home Wi-Fi

Not just a router problem.

I connect my iphone at work to my mac by wifi to share the macs internet connection, this is no longer possible. Tried uninstalling and installing the network again, switching off cellular data allows it to connect, but it switches off again as you look at it, and will not reconnect.

Bizarrely after work on the way home it connected to a free wifi on another parked bus.

I was having this problem since I updated to iOS 4.3.3 yesterday, though I only realised it today when I went into use my college wifi network as I just presumed it was my home network that I was having problems with. Did the whole forget network and re-enter password thing for the home network, wifi symbol still wasn't coming up though it said it was connected. Turned on airplane mode, tried using Safari and the internet worked, so it was connected despite the symbol not being there. Then the airplane mode symbol wouldn't go when I turned it off, so I turned the phone off, turned it on again and all seems to be normal now.

What frustrates me?

Not a PEEP out of Apple. Never is. Know why? Might affect the share price. Pretty insulting.

I have followed and tried everything here. I have a limited amount of data from my 3G connection per month. Apple is making us use that up.

Come on! Make a comment, or "We're Sorry" - other companies do.

btw- A neighbour's daughter can connect with an old non-updated iPhone 3 just fine, still.

What company does that? And why would they say "I'm Sorry" to all those who aren't having any issues?

Call AppleCare and go over the situation with them. If the problem can't be resolved at that level they will issue you a case number and elevate your situation. This way Apple engineers will have information regarding your setup and can use the data to work on any bugs that have been introduced and issue an update. Without that information it may never be resolved.

After 5 days Problems at my home-WLAN with my iPhone 3GS After upgrading to 4.3.2, (it some times worked, sometimes not ) and after trying everything which I found written here at this forum, I powered down my FritzBox for over 10 minutes today. I am not really shure about it but it seem to work now as it worked before updating to 4.3.2. First time after 5! days I have no break since 5 hours ! I really don't have any explanation for that way but maybe it works ?

If someone makes the same experience please let me know.

Sorry for my bad English ....good luck to all of us !

I read through the thread till thus far and I think it is indeed an update problem, because I have the same problems right now.

I'm updating the iPhone 4 software for a family member, I did that one first, internet stopped working even though I can get onto Wifi in the house no problem.

Other iPhone 4s we have in the house (there are two others), using the SAME Wifi connection, but just running the previous firmware, do NOT have this problem.

I think the issue must lie in the new software upgrade. Hope they fix this soon!!!

CORRECTION: found a possible workaround that has just restored my WIFI connectivity after update!

Go to WIFI

Find the network you're currently connected to

Click the arrow next to the name to reveal the IP stats

Click "Forget this Network"

And then re-scan for networks, and re-enter the password, voila, worked for me!

I think the trick is to reset whatever settings the iPhone had stored for your home WIFI, so that it re-initiates the process to get a new dynamic IP with DHCP.

Hope this helps, people!

Hello everyone. I, too, had a TERRIBLE time trying to connect my iPhone 4 (4.2.8 Verizon) and my iPad2 to my home WiFi. I connected, reconnected, restarted, "forgot" network, reconfigured network, etc., etc. FINALLY, by putting in my SECURITY KEY rather than my PASSWORD, both are now connected and stable. AUUGGGHH! Perhaps this might help someone else out there. I run a PC (shhhh, don't tell the Apple folks) and an old, crotchety, but perfectly useful, Linksys WRT54G.

Hi, I'm having the problem with wifi with my iPad 2. I can connect to the wireless network (or seems to be connected) but safari, app store, itunes and any other connected application tells me that is not connected to the internet.

I've tried turning off wireless, turning off the iPad, resetting network settings, forgetting the network; but the problem persist. I don't have an airport router, it's a DLink.

The iPad came with the version 4.3.1 and worked fine, then upgraded to the 4.3.2 and everything fine.... now with 4.3.3 i'm having the problem.

Well-done to PixieCamembert 😎 Unfortunately I don’t have anApple Base Station to try the Airport Extreme option.

The problem I found seems to be the password - like PixieCamembert says I tried my apple account password (the one you are asked togive when you want to download an app) works fine now

Thank F*$%.

Don't do what I did which was everything else first - try this first andsave hours of sync.

Good luck.

hello people,

i have the same problem since a couple of days.

everything worked as intended before, i didnt install any crazy apps or jailbreaks etc.

all i did was update to 4.3.3

i am using an iphone4, german t-mobile carrier, windows 7 and some random speedport router.

i dont get the wifi-symbol anymore on the top, only 3G seems to work now.

i didnt have the chance to try other wifi networks, so i cant tell if its only a problem with my home-network.

in the network settings i do see my home network and it seems i can connect to it, its ticked and looks like it should work, but it obviously doesnt. all the apps that need wifi are telling me that i am not connected...

if i use a net-stat app it tells me my iphone has no ip adress.

i did several (hard)resets, forgot the network settings etc, tried the appstore password - nothing helped.

i am pretty sure this is a bug with the 4.3.3 update.

please fix this asap!

if you guys are having problems you should take your iphones to an apple store and have the techs look at it. apple is pretty good at solving these issues, and if your phone has a serious problem they might even replace it for you.

Same problem here with iPhone 4. Safari is un-usable after 5-10 minutes connection to Wi-Fi. I then need to toogle Airplane Mode once to re-establish a connection.

Can anyone confirm?

Similar problem here with both iPad 2 and iPhone (iOS 4.3.3): Continuously losing enterprise connection with EAP+TTLS+PAP on the largest national Dutch wifi network (EDUROAM). Even a reinstall with iPhone configuration utility doesn't help.

So yes: I confirm the troubles - unfortunately

Is there a fix? Or a solution?

I've read in a couple places to go to SETTINGS:GENERAL on the iPhone4. Go to RESET and hit RESET NETWORK SETTINGS. The phone will restart and you'll need to reenter your network settings. So far, this is working for me.

I do have two wireless systems at home, one is a base station running 802.11G only, and the other is an extreme running 802.11N only (noncompatible mode). The iPhone will only connect to G this way so I don't have the wireless firmware problem mentioned above, yet this fix did work for me. I'd try it BEFORE doing the firmware downgrade on your wireless router.
