No Wifi after iPhone 3.1 upgrade

In fact, this is not due to the 3.1.2 update specifically. It has rarely occurred after every update since the 3G was released. It is the update burning process that affects a defective component in the phone. If you do a forum search of "greyed out WiFi", you'll find threads going back to 2.x updates. It has occurred very rarely and has been covered by warranty.

You're analogy about a car dealership frying electronics during maintenance would make sense only if Apple had performed the update for you and handed you back a broken phone. If you did your own tuneup on an out-of-warranty car and tanked the car's computer, do you really think the manufacturer would cover you, even if you had done nothing wrong?

Did you actually read this entire thread? Very few posts are talking about "greyed out WiFi". Most are about loss of connectivity. There aren't "thousands" reporting this problem.

There is one precedent that may be in your favor. There has been a touch screen issue with the original iPhone, for which Apple has offered replacement on out of warranty phones. From what I can see, this is a lot more common than greyed out WiFi.

My iPhone 3G "could not find wireless networks" for a few weeks starting with the moment I upgraded to 3.1.2, however after much tampering over a number of weeks I could connect to WIFI networks only when initiated through a 3rd party WIFI app. I had about 10 days of bliss thinking it was fixed and then WIFI completely died. I have done multiple wipes/restores/downgrades/upgrades/refrigerations and I now think Apple are unable to build a product which lasts longer than a cheap piece of crud. We are paying a premium price for a product with good design, not one which is long lasting. Apple have made millions selling the phone so unless there is a problem big enough which effects sales, they aren't going to bother fixing it. I'm really disappointed that my phone is near useless indoors but I'm starting to accept it.

If there is any hope of this problem being fixed, people with this issue need better communication with each other. We need a separate forum for our specific problem. It should be something with "grey wifi" in the title as "No Wifi" is too ambiguous, despite being the message the phone displays in Network Settings. When it is ready, we should advertise it on all the related forum pages. It does not necessarily need to be on Apple's discussion pages.

Read the entire, thread? No, not all of the hundreds of posts. Not until your comment anyway.

After reading that post, I gathered some of the information there and returned to the Apple store. Armed with that historical info and able to document that this is a known and recurring issue, they replaced both of my iPhones without question. I was out the door in 20 minutes.

thank you, were you still under warranty or out of warranty with your replacements?

hello again, I just went back and re-read some of your previous posts and saw that you were out of warranty as well...did you go back to the same Apple store or a different one? and what notes/posts specifically did you arm yourself with? I think I will try again also. Thank you!

I also eventually gave up tying restores, resets etc and phoned Apple support.

They have replaced my 3G. I am now on my third replacement. I raised the question over whether there was a widespread wifi problem with iPhones. The support agent mentioned they get the odd wifi problem from time to time but wasnt aware of a larger issue. I find this hard to believe given there is at least two long threads covering this.

I just fixed my second Iphone (friend's) which can see the access point but can't connect. Now both are working with any WIFI and are quite stable. I detailed the steps in a previous post on page 23. Give it a shot.

A semi-fix. On my 3GS I upgraded to 3.1.2 and was unable to see any wifi networks. I did the Reset and all other things I saw in the posts. Nada. As a last effort, tried the app WiFiTrak (free). Holy mackeral! It saw my access point and connected through the app. The wifi symbol showed at the top of the iPhone screen. I went to the iPhone settings and sure enough, it showed as connected. I was able to use the iPhone as normal connected to wifi.

However, if I disconnect from the the network, my iPhone does not see it anymore and I have to use WiFiTrak to re-connect. Semi-fix. This is with a Linksys/WPA. I also have an Apple Airport Express (unsecured) that the WiFiTrak app sees, but will not connect to so I need to try this outside my home to see how valid this workaround is.

Three other computers in my house all connect to all my access points no problem so I believe this is an iPhone issue.

thank you very much for your solution !! i have solved my iusse!
it works on my iphone 3g under firmware 3.1.2 thank youuuu !!!

You can't compare the car stuff with the iPhone.

THE CAR DOESN'T HAVE UPDATES.... I mean you have to tinker with it if you want to make it better

MEANWHILE APPLE PROVIDES UPDATES FOR THE IPHONE AND WHEN THAT UPDATE BREAKS MY FREAKING IPHONE I AM GOING TO SUE THEM WHICH I AM GOING TO DO SOON. Wanna know somethin? If you update through something Apple provides it means they are LIABLE for it. THEIR PROGRAM ITUNES INFORMED ME TO UPDATE AND IT BROKE MY PHONE. ITS THEIR FAULT. THEY'RE SOFTWARE.

They didn't update it but they did tell me to update it. Hey so I'm going to say it was a defective update.

THE CAR DOESN'T HAVE UPDATES.... I mean you have to tinker with it if you want to make it better

Not true. I've had cars with manufacturer updates to the drivetrain control computer and entertainment/navigation system (not maps).

They didn't update it but they did tell me to update it. Hey so I'm going to say it was a defective update.

So, you can PROVE the update was defective because >20 million updated iPhones still work??

I see you "updated" your MSI Wind to run OS X and the 3 other posts you made in this forum were about "updating" your iPhone to unlock it. Apple would say your illegal hacks voided the warranty and led to the malfunction.

UM first OFF "UPDATED" MSI WIND isn't um right???? ***? ITS MODIFIED OSX SOFTWARE BTW so it's not Apple's fault if problems arise on my MSI Wind.

OH AND ABOUT THE CAR UPDATES: YEA TRUE GPS AND WHATEVA DO HAVE UPDATES BUT WHAT IF THAT UPDATE CRASHES YOUR GPS? Exactly. Besides a GPS isn't really what I was talkin about when I say car.... I meant like the engine and stuff.

The iPHone: Um, hey wait oh here's a reference TO XBOX 360!!!! THERE WAS THIS UPDATE WHICH BRICKED A SIGNIFICANT AMOUNT OF XBOX 360s. THAT SIGNIFICANT AMOUNT HAD 360s out-of-warranty and that update bricked their system. They sued Microsoft because that update was created for the 360 and was NOT modified in ANY way yet somehow it bricked it. Yup now a lot of 360 users have an extra 3-year warranty extended thingy... who cares if 70,000 iphones are working but a so called SIGNIFICANT AMOUNT isn't? I haven't really seen 370 replies for one problem be called A SMALL PROBLEM. AS A MATTER OF FACT THIS near-150 PAGE thread I wouldn't really consider SIGNIFICANT. THIS UPDATE *****!!! They were just looking to get rid of the unlocks....

APPLE IS PROBABLY COOKING ANOTHER UPDATE THOUGH to FIX THIS.

I have researched this problem a bit and have come to the conclusion it's a baseband problem. It needs reinstallation which doesn't happen if it's the same version since it just tells the baseband installer it doesn't need to install it again. So yeah.

BUT SOMETHINGS ARE A USER-CAUSED PROBLEM BUT TO ME THIS PROBLEM IS FROM APPLE.
UNLESS THE UPDATE SAID SOMETHING ABOUT "WE AREN'T LIABLE FOR ANY DAMAGES OR WHATEVER" LIKE WHEN YOU UPDATE BIOS (THAT IS VERY REASONABLE) THEN SORRY ITS THEIR FAULT.

When did I say I updated my iPhone to unlock it??? ***? I have AT&T and I have NEVER jailbreaked my iPhone 3G but my friend happens to have a iPhone 3G that has the SAME problem and he had his jailbreaked already so I used his for research.

But my hacking are illegal though you are right.

I was having the same problem. I resolved it by going to Settings/General/Reset/Reset Network Settings. That did it!

Hii You are 100% right ...Exactly the same thing is happening with me tooo. and definitely it isnt the router or something else....IT IS the phone itself... specifically the update. The wii fii tab becomes non-accessible..(watermark). I tried a lot of things including resetting, etc etc and also updating to 3.1.2 but to no avail. The wii-fii still DOES not work.
