No Wifi after iPhone 3.1 upgrade

I upgraded my iPhone 3G to the 3.1 firmware on Wednesday. Since then, my phone can't see any wifi networks. I've tried to do a restore twice, as well as rebooting the phone a couple times, and it hasn't helped. Has anyone else experienced this and found a fix? It's looking like a trip to the Genius bar 😟

iPhone 3G, Other OS, iPhone 3.1

It works!!!

I went to the Apple Store today and the guy fixed my wifi issue in a about 5 minutes. Here is how he fixed it: 1 - Turn on air plane mode. 2 - reset network settings. 3 - turn air plane mode off. 4 - connect to wifi.

This sounds strange but he told me that turning on airplane mode is really the only way you can totally reset all of the network settigs. If you do not turn air plane mode on some settings will not be reset because they are in use.

I hope this helps everyone else out who is having this problem.

Unfortunately, that fix does not work for me. I can always see my D-Link, but it takes an average of 8 tries to connect. No change after following your procedure. Thanks anyway.

Since the iPhone can connect first-time, every time with my AirPort Express and Extreme, my iPhone just needs a software update.

It appears from all the reports here that the iPhone is suffering from at least three types of wi-fi problems. That's a poor track record for one device.

I've had this problem myself, i've managed to fix it for now, but the connection is still not as strong as it was before the last update.

Here's what i've done:

Reset phone, erased all data and setup as a new phone with itunes.

This alone didnt fix the problem, i've also removed the wireless network key on ther router. For whatever reason, the phone will not connect to the wireless when it requires a key. I've checked, and double checked that im typing the key right but it just wont work.

Like I say, the connection still isnt as good as it was before (while i've been typing this it's disconnected and reconnected twice by itself), but it works to a degree, and is better than nothing.

Removing your wireless key obviously isn't ideal, so if you do remove it, i suggest your turn on the mac address control to restrict who can connect to it.

I hope this works for others.

Weak weak iPhone Wi-Fi signal.

It works only if I'm very very close to router (max 2mt).
I tried to restore system 3 times with itunes, to change router, to unlock network, to assign a static IP, nothing improved the signal quality. It's unusable.
I have 4 laptops at home, iPhone it's the only device unable to connect to the wireless network.

I repeat, it's shame that a device built for connectivity has this kind of trouble.
Regrettable!

For those who have been able to fix this issue of broken Wi-Fi connectivity: congratulations. However, the problem is apparently a lot bigger than just this thread.

...and probably many more (lots of small posts).

And then there's all the Web chatter. A small example: http://is.gd/4OUtj

At the same time, why does this seem to be under reported? Questionable battery life received far more coverage.

My latest: I went to an Apple Store last night. The GB was busy, so I stood in the middle of the store and watched my Wi-Fi connection. Connect, disconnect, connect, disconnect... over and over, at various rates. I just watched. It just didn't work. I reset connections, restarted, etc., and it just kept doing the same thing.

I'm convinced we'll find out that there is some batch of iPhones with a chipset susceptible to wi-fi-fry.

Now to make an appointment with the Genius Bar (gag) and see if Apple will just give me a new phone without argument.

The very pleasant experience at the Genius Bar (Apple Store, West Hartford, CT) resulted in a new replacement phone. I know all the homework helped. When I scheduled the GB appointment, I included my last post here (slightly edited, with all the links). I knew what I was talking about.

I went in with the Wi-Fi network settings screen on to show the constant find / lose of the Apple "Store" and "Demo" networks. He then did a network reset and said, "There. It's working." I said, "Give it a minute" and twenty seconds later the network disconnected. He asked me, for the record, if I tried the full reset, etc. He then asked, "So you'll be OK with a replacement phone?" The whole process took 15 minutes.

The longest part of the process is done at home: restore from backup, iTunes resync, etc. (Interesting to me how this is not completely intuitive. The initial restore only restored native apps since I hadn't connected this phone to my iTunes account.)

For those who are under warranty and lucky enough to get to an Apple store, I think if you go in with a positive attitude of understanding and have done your homework, you should have a good experience. Out of warranty, your mileage may vary.

Good luck.

PS. The G at the Bar told me he hadn't really seen this problem. Again, this leaves me to believe there is a specific lot of phones with this problem.
