iPhone 5 wifi issues

Guys, Its absolutely a Software issue.The fact that multiple replacements did not work, But when a wifi router firmware is changed, everything seem to be working, clearly indicates, something wrong with WIFI software in iphone5.

And yes, may be depending the WIFI router brand and firmware you are using , issues could be slightly different like Only WPA secured not working, some connecting and no traffic, Some dont even connect to a Unsecured network (in my case).

I beleieve MODEM VERSION 1.00.16 in iphone 5 is goofy.

FOUND A FIX!!!!!!!!!

I have a Netgear N900 at home and had the same exact problem where my iPhone 5 would connect but had no data throughput. I tried removing the wifi security all together and that worked, except (1) who wants to have an unsecure network and (2) the download speed was still 1/2 of what my ipad and iphone 4s were getting. I then added WEP which somewhat resolves the security issue except the download speed was still 1/2 of what it should have been. I went back to my original WPA2 (AES) setting and of course it stopped working again. I then set my router to WPA (TIK) & WPA (AES) setting. The router gave me a pop up warning indicating that WPA(TIK) will only give me 54Mbps but still allowed me to choose 450 Mbps. My iphone 5 is now connecting to the rounter with WPA security just as I wanted and is downloading at the same speed as my ipad or iphone 4s. I haven't tested my download speed is on my local network to find out if I am getting 54 Mbps or 450 Mbps but at least for internet access purposes my problem has been resolved.

...and the next person who posts (for the millionth time) that the fix is to "reset network settings" is going to be devoured by an angry mob of AES bug infected iPhone zombies who have been scouring these forums and the internet obsessively, looking for brains and finding none.

C4RLOCO seems to really be on to something. If you have the AES bug, go to www.hwaddress.com, enter the 1st 4 digits of your wifi address (general>settings>about). Report back if you have the Apple or the Intel wifi chipset.

Agreed. Thanks for the information but does not fix the issue. This phone should stay connected without miles sing with the router settings. Also, that won't help for those that travel. We can't ask everyone to change router settings for us. Apple needs to fix...

I'm on my 2nd phone with same issues. None of the security setting changes on my WiFi router solved the issue.

@C4RLOCO: Thanks for your post regarding WiFi Chip manufacturer (saw it on the other forum that was WPA2 specific: https://discussions.apple.com/thread/4339516?answerId=19861413022#19861413022&ac_cid=tw123456#19861413. Seems like you're on the right track.

My current iPhone5 that will not connect to my home network is also Apple:

68:96:7B68:96:7B:00:00:00 - 68:96:7B:FF:FF:FFApple Inc

I have an open case # with Apple Support that has been elevated to the engineers.

But until (and IF EVER!) there is a software fix for the WiFi on iPhone5 for these Apple made WiFi chips... it's time to head back to the Apple Store ... again !

Hope someone is hard at work at Apple somewhere

I have the 98:B8 Apple Wifi chip. I am able to connect to Wifi but I am getting about 1/2 - 2/3 of normal speeds. I am also getting weird behavior on the cellular side. My phone is getting bad reception in areas where my 4S never had problems. The signal bars show that I have no service, but I am still able to run speedtest and surf the web. It's like the phone does not recognize it is connected. The battery drains as if the phone is trying to find a signal even though it is already connected. I have to restart the phone at least once a day in order to get the correct signal strength to display. Is this a hardware or software issue? I'd like to get a replacement before my return period is up if there is indeed a hardware problem.

I have changed my router ip to 192.168.1.1 + DHCP reservation. I then restored via iCloud. During the restore, speed was very consistent & high. I was able to play Youtube videos during the restore with fast preloading/caching (tested with a 30 min video, did not stop a single time !). As soon as the restore ended, my speeds got back to 50k/s & inconsistent. My chip is an Apple one (68:96). Feels like a software issue for me..

I can confirm you are right on this. At my work we have 33 people with iphone 5's. 7 of them have no problem with wifi and the rest of them say its so slow it cant even be used. So I checked all the mac address's and the 7 that work no problem are intel and the ones with issues are apple. I have an appointment at the apple store tonight so I will see if I can get mine replaced with one that has an intel chipset.

Excellent initiative mp3king82.. this information is what I need to give more weight to my theory (For new joiners please see: https://discussions.apple.com/thread/4339516?start=0&tstart=0 )

Good Luck with your replacement Sir!

P.S: If you find my inputs helpful, please don't forget to click the "This help me" link 🙂 I am pretty sure that a lot of people will now what to expect when replacing their phones without feeling like a lottery. You can ask a new phone until you get the one with the Intel chip.

The intel ones at my work started with 88 and 8C. It seems there are a few different ones. When I go to the apple store im just going to use one of there computers to check the website and make sure its intel before I leave the store.

PS: I have also printed this complete topic to show them so they cant deny there is a problem. My boss loved me using that much paper lol.

Im thinking this must be a driver issue. I know some people with older phones and ipads and some have problems with wifi on ios6 but were fine with ios5. I just checked and it seems apple used both intel and there own chips on these devices as well. Brings hope that maybe this will be fixed in an update.

Hi everyone I have a 4s and I too have found it very fustrating after upgrading it to ios 6 but I changed my wifi to guest and the internet if working alright for now. i guess i will wait until Apple comes up with a solution.

iPhone 5, MAC- 54:26, Apple Chip, Sprint - very slow, inconsistent connectivity and throughput on both cellular and WiFi. Apple needs to come out with a public statement and fix SOON! Been an Apple fan for years but am starting to lose faith in the quality of their products!

You can check your WiFI chip manufacture company here:http://www.hwaddress.com/ (You only need the to enter the first four letters/numbers of your MAC Address. Where do you find your MAC Address? Go to Settings->General->About ->Wi-Fi Address

What I would like to know is IF these connectivity problems are down to which chip you have in

Our iPhone WHY does my iPad now not connect properly after updating to IOS 6? Neither does my IPhone 4 or iPhone 5. The common factor in all of this is IOS 6!!!!!!! No problems before I updated, now it's a total pain!!!!
