Q: Wi-fi issues with new 3.1.3 update

My Bluetooth connection seems OK - well it connects to my car kit perfectly fine.
Its just the wireless thats the issue for me...... :o(

I have tried a restore 3 times now.

Did you restore your iPhone from your iPhone's backup, or as a new iPhone or not from your iPhone's backup?

Wi-Fi settings are included with your iPhone's backup. If there is a problem with your iPhone's backup or with the wi-fi settings included with your iPhone's backup, restoring from your iPhone's backup will also restore the problem.

If the most recent restore was not as a new iPhone or not from your iPhone's backup, give this a try. Before doing so, you can try selecting forget this network with your iPhone - Settings > wi-fi. Select your wi-fi network to view the settings for the network. At the top of the settings for your wi-fi network, select Forget this Network. This will require re-joinging the network.

If no change after doing so, go to Settings > General > Reset and select Reset Network Settings. This will require rejoining your network along with any other wi-fi network you have access to and have previously joining with your iPhone.

If no change after reset network settings on your iPhone, try restoring your iPhone with iTunes as a new iPhone or not from your iPhone's backup.

If no change after this, more than likely your iPhone has a hardware problem. The iPhone includes a one year warranty. You can call AppleCare or make an appointment at an Apple store if there is one nearby.

For what its worth, I did a restore after updating to 3.1.3 and having this problem. It seems to be functioning normally now, although I did lose some precious iPhone pictures in the process. What I don't understand is how my iPhone still has 3.1.3 even though I reverted to a backup.
Oh well, at least it works.

You are very lucky becuase I have restored my Iphone and not applied any backup and the issue continues.

Thanks for the info Allan. I will try that tonight - and yes I had been restoring my backup as well.

I have just reset my network settings. Since I only have my home wireless on my iphone that doesnt bother me too much. I will connect to it when I get home and see if it makes any difference.

Didnt want to have to set everything up as a new phone all over again TBH - but as a last resort I will give it a go...

Thanks again, will let you know how I get on....

Greetings,

Everything is working correctly on our iPhones, after the 3.1.3 update. No issues of any kind.

Cheers,

The iPhone's backup does not include the firmware or operating system. The iPhone's backup includes various settings and data stored on the iPhone only. When restoring an iPhone with iTunes, the current firmware version will be installed or re-installed regardless if you choose to restore from your iPhone's backup or as a new iPhone or not from your iPhone's backup, which is selected after the firmware is re-installed.

I'm completely sure that this is a bug of firmware 3.1.3 and not a hardware issue.

hey! looks like everything is running good now!

I reset my network settings and reconnected to my wireless. Since then things have gone back to normal and I'm pleased to say my connection speeds are back up to the 6-7MB I used to get before.
Everything else also seems ok now on 3.1.3.
Thanks for your help guys.

I just upgraded to 3.1.3 last night and have been wondering why I didn't see the wifi icon at the top of the screen anymore. In the wifi settings area, it still says it is connected to my network, but I could tell by the speed that it was using the 3G net instead of wifi.
I tried to reboot the phone, reconfigured the network settings by forgetting the network and reconnecting, and even restored a backup of my phone. Nothing worked.
I can hit the button to renew my IP lease under wifi settings and it connects right away to my network. But within 5 seconds all information dissappears and I get a 169.254.x.x IP address. ***! Did Apple kill the wifi antenna???

Have you read all posts in this thread?

Have you also tried resetting network settings on your iPhone - Settings > General > Reset > Reset Network Settings?

If no change after doing so, wi-fi network settings are included with your iPhone's backup. If there is a problem with your iPhone's backup or with the wi-fi settings included with the backup, restoring from the backup will also restore the problem.

If no change after restoring from the backup, have you also tried restoring as a new iPhone or not from your iPhone's backup?

I might be wrong, but this is my experience.
After my update to 3.1.3 I stil had a connection with my Airport network. But I could not connect with Apple Remote or Rowmote in any way. It took me sometime but this I noticed;
Iphone > Settings > General > About > Wi-fi-Adress was now different from the adress which I gave permission to access in my Airport Extreme Router. Only the last letter had changed. When I changed the settings in the AE it worked as before.

Iphone > Settings > General > About > Bluetooth adress is now the old wifi adress.

Things to still seem a little flakey with wifi though. Most of the time its Ok for me, but at times it will just slow down for no apparent reason - I mean slow enough to be almost unusable. The connection itself seems fine, and I can use my laptop at normal speeds all the time, so I know its the iPhone itself.
After a few hours things just go back to normal again!

Hi mates,

Let me explain my experience: After mi wifi issue with new firmware 3.1.3 I decided to downgrade to 3.1.2 but the issue continues, so I did upgrade again to 3.1.3, and after that I was able again to connect to my wifi network, so I have no idea of what could happend to resolve the issue.
