Strange WiFi problem on iPhone 3G after 3.0 update

Thought I pop in here:

Nice to see fellows that suffer from the same problem. Upgraded my carrier-free iPhone 3G from Italy a few days ago from 2.2.1 to 3.0. Since then bad WiFi reception in the beginning and now none anymore. I also have the impression that the mobile data transfer rates decreased. But hey - the battery life indeed increased - what a smasher!

I went through all procedures that are floating around here:
- Putting the iPhone in the fridge for a few minutes - helps for a while
- Changing the WiFi parameters, like encryption, channel, password, dynamic or static IP, and so on - did not do anything for me
- Restoring network settings - did not help at all
- Full FW restore with factory setting (no personal settings loaded at all) - no help
- Opened and completely disassembled the iPhone to check all connectors that may have come loose - that helped for about 2 days

What I did not do so far is to restore to 2.2.1 but I read somewhere else that this does not seem to help either.

So the only thing that changed as well with 3.0 is the baseband. Mine is 04.26.08. And the baseband cannot be restored the regular way. Even if you revert back to 2.2.1 your baseband remains upgraded. I will see and check if I have bootloader 5.08. Then I will give it a shot with the 3G Fuzzyband Downgrader. I keep you posted.

I am reaching here but I have the impression that it is not OS 3.0 alone that messed up the Wifi on some machines. I also heard reports that some of the new 3GS are affected as well. I believe it is a certain batch of communications chips used on a few iPhones that does not work well with the latest FW and baseband upgrade. Question here: How many are affected and is the number high enough for Apple to invest resources to get it fixed on a software basis. And most importantly: is it fixable at all with a software update or was the affected harware already inadvertantly damaged?

Whatever it is I strongly hope that Apple will at least - for their own sake - release a statement soon and not leave several hundred customers p *ed off!

For my case ( iphone delays to join network since upgrade to 3.0)
my home wifi is airport express, and security is WPA2.
Also with time capsule and WPA2 i have the same problem.Please note that with airport express ,I get a better signal (always at the same place for wifi and for iphone).

I've been testing with an iPhone running the 3.0 OS. When previously running 2.x version the Auto-Join feature/option would see the iphone always connect to a specific SSID, call it "MCONNECT" (profile setup using dot1x/WPA Enterprise/TKIP/PAP), when Auto-Join was enabled. However after upgrading to 3.0, auto-join doesn't work for the profile setup as above, i.e i can move from carrier network (3G) to the work WiFi network, and even if the specific wireless network is available (and auto-join is enabled) the iphone doesn't automatically connect (auto-join) to the SSID! The iPhone instead connects to another SSID; i therefore have to manually connect to "MCONNECT". I thought that the Auto-Join feature is independent of any profile that is installed on the iphone. It's annoying that this has stopped working!! Has anyone experienced a similar problem??? At this stage this looks to me like a bug...

Any info would be appreciated.

Similar Problem her, however just noticed something very strange:
The iPhone connects properly to my home WiFi as usual, but no connection to the Internet whatshowever. All worked lie a champ prior the update to 3.0 and my network is unchanged.
Now comes the strange thing:
I CAN connect to other computer (e.g. My Linn DS player) within my home networt without problems.
Other Computer on the Network can still connect to the internet from my WiFi port so I can exclude this.
Full restore and rebooting multiple times of the iPhone make no difference. WiFi connects just fine, but no way to get anything working except within my own Home network.

Now this seemed to have fixed it for me:

settings>general>reset>reset network settings.

Next time I connected to my network it asked as expected for the password and then.... working again as usual.
Hope it will hep some of you too

I did notice the same issue as most of you here - and found the reason ...

On friday I received to brandnew T-Mobile iPhones:

- iphone 3G S 32GB - setup was completed within a few minutes

- iphone 3G 8GB - shipped with fw 2.2, asked for the fw update

So I did first complete the update with iTunes after I connected the phone the first time to the computer. After starting the activation I did the same steps as before with the 3GS.

I started to setup WiFi and noticed, that the WLAN level was very week compared to the 3GS (full level / 3 segments), it only did show 1 segment, but also did find my WLAN SSID.

Connecting failed, I did re-enter the key 2-3 times then I started searching the internet for this issue and found this discussion.

In the meantime I investigated the problem deeper (I'm an IT professional) and I found the only solution that will help everybody of you - but won't satisfy !

All hints and tips with "reset" etc. didn't work !!

But try this, prepare the WiFi connect, enter you key and before klicking to the "Join" button go very close to the WLAN antenna of your router. When being in a range of ~ 5 centimeters everything will work fine.

My routers are AVM based, one is a 7270 with WLAN b/g/n enabled, the other network in another location is a Speedport W900V, but the hardware is also made by AVM. Both networks are working fine with WPA2(CCMP) with a 24-char key and all of my other equipment, including the iPhone 3GS.

On monday I'll swap my iPhone 3G, it's no questions that this is a hardware issue (iPhone 3G serial 889224......)

Regards,

Mike

At least its not just me.... I've been having the same issue with connecting to my own wireless router at home. Prior to the upgrade, I had no issues at all with wifi anywhere. After the upgrade, I can find and connect on wifi everywhere else by MY OWN ROUTER! I've reset my network connections on my iPhone 3G several times as well as my router. I've done everything I can think of and nothing. This blows....

@ptbeale - we don't "rant" without the reason and without details. Many of us are computer professionals and for sure "we know the drill" about troubleshooting.

There is no reason to specific about WEP, WPA, WPA2 etc. settings because:

1) all other iPhones with 2.x system work great on the same place! Zero problem!
2) all other Macs and PCs work flawlessly too!
3) for public hot-spots we can't always know the settings, but we can see that many iPhones 3.0 no longer can connect to them - and yet all other with 2.x work nice as always. And if we do, for sure we can't make public hot-spots change the settings just to please 3.0 system, right?

Also, there are more and more reports that indicate that it must be some sort of a hardware problem.

On the Croatian user group forum we have made a pool and the results are interesting:

1) 80% od iPhone 3.0 users has NO TROUBLE at all, everything works perfect!
2) 11% has problems, sudden disconnects, overheating, problems in finding networks
3) 9% reportered DEAD iPhone after 3.0 update - no wirless at all!

That's almost 20% of users with some sort of a trouble.

Hi folk I am from the UK as all the others on here my Iphone was 7 months old and worked fine no troubles at all apart from missing very basic functions that a £15 mobile from asda/wallmart can do like forward a text or send picture messages.

Like many others hearing there was to be an update to give us these very basic functions I downloaded and instaled into my iphone 3.0.

form that day I have no wifi Use at all I see my home network I can login connect to my modem but soon as I use my iphone to go onto Safari my wifi connection gets dropped straight onto 3G then a slower network.

So after a full restet and a new download of 3.0 and then deleted the old download from itunes I then instaled it again no change done resets (no change)

So I went to the shop I bought my £342 Iphone from and the guy in the shop could not get it to work.

so now after waitting a week I got another new Iphone 3G 2.1 yes my networks was fine then i updated to 3.0 guess what no wifi very same as my last phone.

I can see my network it says its connected but when I use any app that need the wifi its drops the wifi straight away.

for some stupid daft crazy reason when you go to the app store for updates it says the updates are above 10MB you need to use wifi "why the **** if you want to run your batteries down let us my wifi does not work thanks apple".

I can't laugh hard enough when apple slagged microsoft this is going to backfire big time.


So anybody on 3G if your having this problem don't be a mug report it let others know.

please note I am on 3G Pay and go I was so stupid to pay outwrite for the Iphone.

I dont have any authentication however putting the phone right next to the router and pressing join still results in unable to connect to my or any other network.

Same here, I've got the original (UK) model and it's been fine through all the previous updates, but 3.0 has broken the wi-fi even at home with 2 airport extreme (dual band) airports.

Also my public folders on our Kerio server have stopped showing under mail. the other IMAP server we use that doesn't emulate an Exchange server (no Push e-mail) stills shows all the public folders

We're buying a couple of 3GS model in July so I'm hoping they will be ok.

I hear 3GS is having the same problem HOWEVER I FINALLY GOT IT TO WORK AFTER SPENDING A FULL WEEK ON THIS PROBLEM.

The problem is the wifi chip is getting hot... I turned off the phone, put it in a plastic bag and stuck it in the freezer for 10 mins.. Immediately after turned it back on and voila! it connected to my wifi network! I can't believe how apple has really gone cheap as far as the hardware goes on this phone considering how much we pay for this every year!!

I am still amazed that this problem is due to Apple's horrible hardware software Q.A. and have determined that my next phone will certainly not be purchased from this shotty manufacturer!

I had the exact same output as yours after looking at the error log. Were you able to figure anything out? I was thinking that some setting was still being retained after multiple restores, or I could be wrong.

"put it in a plastic bag and stuck it in the freezer for 10 mins"

???

BUT IS IT AFFIDABLE???I CAN'T TRUST THAT THIS METHOD RESOLVE THE PROBLEM

Yes as long as it is in the bag you will be fine... if youre worried then just lay the iphone on an icebag for 10 mins outside it should have the same effect.

I spent the last 48 hours to get one of my Iphones back to normal after updating the 8GB one to 3.0. WiFi still not working. Here are the things you can leave aside. They won't work.

- Putting in the freezer.
- downgrading to 2.2.x.x
- lots of stuff apple won't support.

All these things won't help. My suggest is they F *ed up the baseband. As long as you can't downgrade this, nothing will help. Not until those surfer dudes from california will do a patch. The strange thing is that my 16GB Iphone work fine. G3 is even better. And Wifi runs perfect. But the other one doesn't.
Maybe they use different Wifi chips for lowering costs.

For me as a microsoft user since day one, I'm very satisfied that Apple is just another manufacturer of mobiles and computers. Accept with a poor service. You freaks are no gods, SO DO YOUR F *ING JOB, THAT'S WHAT YOU PAID FOR!
