Strange WiFi problem on iPhone 3G after 3.0 update

Heres another one of those solutions that has temporarily worked for me over the last 2 days and continues to work. wifi works easily and connects to all saved locations and receives push email well before my other iPhone running 2.2

goto settings>general>scroll down to profile

If there is anything saved in there delete it and do a hard reset.

I was going to try one more thing if this didn't work. if some has done this please let me know.

do a fresh install of 3.0 and do not run a backup so its like you just took it out of the box. so no contacts, no apps except the stock ones etc. then see how your wifi works.

let me know

sorry but where is "scroll down to profile"?
Today I have called apple support and they say that i must send the phone in assistance!
I can't trust..I have received it a month ago from assistance!

I'm starting to be really ****** with this. My wifi also doesn't work, and I've been trying all sort of tricks and hacks that I can find on the net, and nothing! It still doesn't work.

Apple should have seen this coming before releasing 3.0. We pay a lot for this devices and we should get bug free (at least the major ones) software.

If someone can find a way to solve this problem please let me know to my twitter account: https://twitter.com/InOmniuParatus

same problem....wants to revert back to 3g even when I am 2 feet away from the wiFi home setup...annoying as h..l... suspect this is good ole AT&T problem....nothing I have done to correct this works....

Profiles are basically xml config files that act like plug-ins for the iPhone. They can configure things like Wi-FI, network, passcode, email and VPN settings on each iPhone. They can even be used to install certificates. if your not seeing any profiles then you don't have any. i had one installed to access my university's wifi network.

have you tried reinstalling 3.0 with out restoring any of your information and seeing if wifi works then???

As someone who suffered with the fuzzy picture bug going to 2.2.0, I feel I have already been bit by buggy upgrades. Typically I enjoy bleeding on the cutting edge of technology and would love to try upgrading to 3.0 on my iPhone 3G.

I am wondering, does anyone know Apple's rationale for not letting you back out updates and revert to an older version of the OS ?
Seems like providing an undo path for upgrades would go a LONG way toward actually getting better quality s/w faster. More folks would be willing to risk messing up their iPhones to test out the updates if they knew they could go backwards. At least there wouldn't be so many angry, disillusioned folks running around.

Seems like the "smartest" folks who understand the risks of a new OS (especially *.0) are the ones best suited to check it out, yet they are also some of the least likely to do it because they dont want bricks until *.1 comes out.

i would love to fiddle with 3.0, but I cant afford to lose my wifi ...

and no, i dont want to go the jailbreak route to revert to earlier versions,
Apple should provide an approved method to undo OS updates.

Obviously they must have a rationale for not providing undo, I just hope it isnt an ego thing out of fear of admitting s/w bugs exist.
The iphone is a COMPLEX beast,to expect it to be bug free is simply ignoring reality. So plan for it, allow reverting, admit bugs, work with the user community, to minimize them.

OMG hahahahaha as i sit here and try to help out my phones wifi wont stay connected anymore. i thought i fixed it for sure. this problem is driving me nuts. we should all just go to the nearest apple store and throw our phones through their glass windows. maybe we will get a response then!!!

hmmm, sounds too familiar ... everything was fine in os 2.2.1 then updated to 3.0, afterward i thought something might be wrong with iphone internals, but wifi works when directly in front of signal box, a few feet away wifi is intermittent while laptop is still receiving strong signal ..

I have just returned from trip to Italy to return the phones. At Vodafon and TIM they have no idea about any Wi-fi problems and they say that Apple will just replace faulty phones in up to 4 weeks.

However, there is one more annoying catch - all iPhones bought at Vodafon can be returned directly to Vodafon store for the service, BUT all iPhones bought at TIM or TIM reseller can't!!! Can you beleive this? They say that I have to return iPhones to the central TIM service statiton in the city center (I just couldn't make it in time) and the Media World phone specialist even couldn't tell me the correct address or the phone number! "You know, it's in the center, near the fontain..."! 🙂 So, I have returned with only half job done - Vodafon iPhones are in for the service and TIM iPhones must wait another trip ot Italy.

Is there any less painful way to buy and service iPhone?

I used the iPhone configuration utility to show the console messages related to my iphone being unable to join wireless networks the messages during the connection/rejection process are as follows:

I have spoke to customer care and they offered a replacement carrier locked iphone for my factory unlocked iphone. Gotta admit Apple is now the worst CS i have ever dealt with and in this life or the next they will reap my vengeance for their utter incompetence.

Sorry to hear some of you guys having Wifi problems. I can feel your pain.

After restoring a backup from my 2G phone running 2.2.1 to my new 3GS phone running 3.0, my Wifi worked initially but would disconnect itself after sleeping the phone. I read somewhere that deleting the connection, and recreating it, might help. So...I blew away both my Wifi connection (and my Exchange Email connection with work), rebooted/restarted the phone, and recreated from scratch. As of that time, my Wifi connection at home has worked fine.

Of course, your mileage may vary on this. I just want to share my experience as it's been a positive one.

I worked in customer service for five years and I always felt corporate Ideology of customer service is a mere joke. Machines, Automations, Scripts,Surveys..no personal touch at all. They spend thousands of dollars to reach customers to get feedback and opinion so they can improve their service but here we are in Apple's own forum not one but hundreds of users posting comments with a similar issue and what is apple's response? Nothing!

isn't there any good news by apple??I can't say if send the phone in assistance or attends an update from apple!what can we do?

Hi all. I have a similar problem. Did the update and wi-fi has gone mad. It either gets no signal at all, switches itself off or won't load anything at all. Also the phone has slowed right down games are slow to load and play, even entering the lock code is slow. I have no idea what's going on have tried using memory info app but even this does not help it's all gone T..ts up as far as i am concerned and would like it fixed. ASAP.

Hello. After reading this thread, I thought I might as well chime in. My story is the same: Everything worked perfectly before 3.0, and now, after the upgrade, Wi-Fi does not work. Hopefully, Apple will fix this soon. Good Luck, everybody!
