Wi-fi issues with new 3.1.3 update

My iPhone has not been working since the last two firmware upgrades Thats nearly THREE MONTHS!!! I had hoped that v 3.1.3(7E18) would include a fix for this WiFi issue as well as patching security flaws in the OS.

I think that the amount of people with broken devices that have written in to get peer advice from other users warrants some kind of annuncement from Apple.
I have already written to a couple of journalists to try and escalate this to Apple.

Absolutely CONVINCED this is a software issue that relates to de-throttling the WiFi chip. Or my own pet theory that different, earlier batches of chip refuse to work with the software release hence seeing people with older phones suffer.
Putting the phone in the freezer is a crackpot scheme and it probably is the switching off and rebooting that is helping these users. I would defintiely not reccomend it.
I am so cheesed off with Apple, they should release a standalone installer to roll-back the operating system to an earlier version....

apple are a shower of w**king ba**ards, i have an early 16gb iphone and have not bein able to access wifi since i upgraded to 3.1.2 last year, and apple will not accept responsiblilty for it, they want over €200 to fix it, extreaml c**tish if u ask me!!!!!

not a happy apple customer!!!

same problem, here. i have 3 airports in my house -- plenty of coverage -- but as of OS 3.1.3, it no longer connects to wi-fi. it sees the network, but never connects. it's constantly on 3G, which of course drains the battery.

there's at least one other thread in this forum on the same topic. this is without question an OS 3.1.3 issue.

apple, please don't make us wait months for the fix. this is a serious issue!!

This is why you shouldn't bother with updates unless they provide us with something valuable. Yeah every update that apple releases says it will extend battery life blah blah blah..yeah right.

I'll stick with my 3.1.2 until they give me something I don't already have. Customizable lock pattern, background, different text tones, live weather updates without having to open up the weather application. So, every update that apple produces until then are worthless. So y'all shouldn't even update to save yourselves all the stress 🙂

just upgraded... no it refuses my sim card _ _" what a ** Lsit ...apple has neglected us as a customer...somebody should bring this matter to court .... Im in Indonesia, i bought my phone 2 wees ago, the wifi is abit trouble, but with wififum its solved...NOw, it rejected my sim card !!!!

This is ** Lsit

Hi Goaliegeek, in my first reply I said I reset my Network Settings as described on Apples Network Troubleshoooter. I was on 3.1.2 at the time. After 2 days of rock solid stable WiFi connection at both home & work I took the plunge and upgrade to 3.1.3. I have to report that I've had no issues with 3.1.3 yet and my WiFi is still solid.

My guess about the iPhone WiFi setup is that it holds WiFi info in some memory registers and as time wears on they gradually fill up.

I think Apple Devs need to check this out and come up with a way of ensuring that those WiFi connections users use most often are protected and that those that are 'drive-by' are treated as temporary.

So that means permanent memory registers for permanent WiFi connections and temporary replaceable memory registers for street based WiFi from phone operators, etc. A method to easily clear a permanent entry would also be useful as the current "Forget this Network" appears to be broken.

personally, I think the whole "Reset Network" approach is a poor method and doesn't enhance the user experience.

Suggest Apple's Devs run up some usage scenarios and then code for the overall best user experience.

Hope your problems are fixed soon.

My iPhone is only a month old 32GB 3Gs. My wifi used to work perfectly fine with 3.1.2, but since upgrading to 3.1.3 the wifi is rubbish. This was my first update since having the phone, and I didnt think it would cause more problems then it would resolve!

I have a 10MB Internet connection via cable, so it is not shared.
On my laptop speedtest reports I'm getting the full 10MB.

On my iPhone I used to get between 6-8MB.
Since the recent 3.1.3 update I'm getting silly speeds via my iPhone speedtest.net app. It now reports around 0.3MB!

I can still browse the web ok but I can't watch any YouTube videos or iplayer etc.

If I switch to 3G it's actually better then my wifi and I can watch full YouTube videos without any stutter at all.

Why is my 10MB wifi connection so poor on my iPhone now?

I have tried a restore 3 times now.
The first time I thought things had improved, but a few hours later it was back to being rubbish again. The subsequent restores have made no improvements. I'm actually having to switch wifi off and revert to 3G to watch a YouTube video!

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.

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....

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 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.
