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 😟
Same problem here. I have an iPhone 2G from a buddy, no WiFi with OS 2.1, nor after the upgrade to 3.1.2 - and this iPhone is
not JailBroken nor modded in any way. Have restored it multiple times. I have another iPhone 2G, WiFi works perfectly fine; had 3.0 on it - works. Upgraded it to 3.1.2 - works. Have an iPhone 3Gs, running 3.0, works perfectly fine. The latter two connect to any WiFi access point I try to connect to. The first iPhone (2G) will not connect to ANY WiFi access point. Most times it simply doesn't see any; when it does see them, it will connect, ask me for the password, then have a checkbox next to it for a brief second, then it goes away. When I click "connect", it tells me "unable to connect to specified access point" or some such error (don't have the phone in front of me right now to get the exact message.)
The problem CANNOT be hardware related, since WiFi worked on the iPhone 2G when it had OS 1.x and stopped working after it was upgraded to 2.1.x and higher.
Hopefully Apple will come up with
some type of solution for those iPhones (2G AND 3G/3Gs) that are affected. <sigh>
Magic!!!! wifi worked fine 1 month ago when I bought my 32GB 3gs, upgraded to 3.1.2 then the probs started, only fix I found was to manually enter my router details then it was able to find wifi signals again until I would reboot then would have to manual enter the first time again. went on holiday for a fortnight and stupidly turned my phone off one day so been stuck with no web!
Now thanks to your recommendation SOSDD Im back in the wifi zone!!! wififofum workin a treat for me! 😀
I got my wifi working again. It was greyed out so I couldn't even select it. But I turned off the push notification on emails and then rebooted (home+power for 10 seconds).
Now it works. I don't want to turn the phone off again to see if it still works, but I thought I'd let people know in case it works for them.
It could just be that I hit one of the lucky times when I restart and it works though (that has happened once before).
Good luck everyone! I'm sure I'll be back here once I reboot the phone in the future though.
For my case installing wififofum worked!! I was having the same issues, my wifi would not connect to any hotspot. It was working fine throughout the day picking up different hotspots at the store and driving around.
The odd thing that happened to me, was I talking on the phone, and sending an email at the same time when all of a sudden my phone drops the call, screen freezes up, and I had to shut it down (not a hard reboot). When the phone finally turned on it was having a hard time connecting to AT&T, but eventually did.
Of course at that moment I didn't think of checking for wifi, but 15 minutes later when I made it home, it was not connecting. I did everything other folks have posted reset networks, blah, blah, blah. I was about to believe maybe the chip fried till I saw your posting and figured why not buy the program. Thanks for the advice SO SDD. I'm going to keep my fingers crossed and hope I don't have one of the bad wifi chip batches like others have posted.
Hi All, I also had 8GB 3G iPhone and did the 3.1.2 update and WiFi never worked again. BUGGER! Tried everything, sold the phone. Someone said to turn off 3G and try again which is about the only thing I didn't do. I did reset network settings countless times, soft reset, hard reset etc - all to no avail.
I'm on my 3rd iphone 3g due to this wifi problem. I was still within warranty...got phone in april of this year. I told genius bar when I exchanged it just 2 weeks ago that I will be coming back each time this stupid wifi goes down all of a sudden on my phone until apple decides to fix this!
I had been running 3.1.2 on my 3GS 16GB iPhone with no problem. This morning I noticed that I had no WiFi at all! The second iPhone in our house has no problem. After hours of searching the Internet and reading most of this thread I decided to restore my iPhone. I got WiFi working again and then used my backup to restore back onto my iPhone. I currently have WiFi available in my settings, but am concerned that this is only going to be temporary. My iPhone is not jail-broken or anything like that and is just under six months old (got it the day they were released in Australia).
Only tine will tell, but I've never had a WiFi issue with an iPhone 3G or 3GS with all firmware versions from 2.0-3.1.2, on my home, office and multiple other private and public WiFi networks.
FYI, if you do have issues, try Settings > Reset > Reset Network Settings - you may not have to restore.
Apple hasn't announced any updates and rarely does in advance. There is no schedale for updates. I wouldn't hold my breath for a fix anyway, since the problem is in your phone, not the firmware.
Well I
am waiting for a fix since wi-fi became problematic immediately upon installing the update. Since I can connect with no trouble to Apple base stations but have great difficulty connecting to a D-Link that no other device has a problem with, then it's a software problem at Apple's end.
I acknowledge that other people are having hardware problems otherwise freezing the iPhone wouldn't help.
Apple seldom admits fault unless they get a lot of bad press. So far, I haven't seen any media attention for this problem. I've requested some media types look into it, but they've remained silent. I suggest everyone start contacting your favourite tech web site, podcaster, blogger, tech media pundit and point them to the threads on this forum.
