    Maybe there will be a recall like they did with the iPod Nano. That would suck...but at least I still have my old iPhone 4 as a backup.

    Wow...NONE of these fixes help me.  Set it to WEP, nope.  Renew lease, nope.  I've done every single fix on here that was suggested and my wifi speed is still registering slow.

     

    the funny thing is I never would have noticed until I started downloading songs from itunes...they were going painfully slow.  Safari works fine though, it's lightening fast.  I just don't understand.  I really really really hope it's not my phone.  The nearest Apple store is almost 3 hours away from me.  I already sent my iPhone 4S to gazelle so I have NO backup.  I really hope this is a software issue

    Nah, I haven't deactivated it yet. I didn't upgrade, I added a line and then am going to remove data package and make it a $9.99 ghost line until it falls off in April. Better than paying $750

     

    EDITED to ADD: One thought about slow loading apps that I just noticed here. I have two phones and an iPad. When I download an app on my new phone, it also loads on my other phone and ipad automatically. So perhaps the data speed is slowed based on numerous devices? Actually my download isn't TOO slow. It was comparable to my iPhone 4.

    I live in the middle of nowhere MN. We are so remote that there is absolutely no reason for us to mess around with creating a secure connection. All of my other comps/devices connect just fine and I never had issues with iPhone 4. There is defintely something wrong with the iPhone 5. It will connect on occassion, but it is simply just OK when it is connected. It drops the signal a lot, and can't even find the signal half the time! Apple please tell me this is a simple fix and you are going to send a firmware/software update!

    It's not a hardware problem. It's iOS 6.

     

    I didn't have the problem until 5 minutes ago. Both my iPad 2 on iOS 6 and my iphone 5 suddenly stopped working on my home wifi.

     

    Reset my router and both devices. Nothing helped. Both started working again after 5 minutes.

     

    They need to hurry up and release 6.0.1 or whatever the first update will be.

    Apple - Fix this!!!!!!

     

    Apple, THIS IS WHERE YOU NEED TO LOOK on iOS 6 regarding "WIFI Lockout"!!!!!!

     

    When this happens (WIFI freezes up aka "WIFI Lockout") – you can not get on internet while using WIFI!!!!!

     

    You could be in the middle of surfing or using any app that makes data calls based on DNS and suddenly you can go no where or do nothing!

     

    Yea sure, you can restart the WIFI connection, but WHO wants to CONTINUALLY do that?????

     

    Apple (or any curious iOS 6 user that wants to see my point), when this happens open up a browser before you reset, disconnect/reconnect WIFI ( I tried both safari and chrome ) and type type 74.125.227.144 (google) and then “go”. A google search page will come up and you will be able to execute a search. (of course any link you click on will not work as it is dependant on DNS resolution)

     

    Non DNS traffic works so the issue is not the WIFI connection to the access point!

     

    APPLE, FOCUS ON FIXING THIS DNS DATA ISSUE AND YOU WILL GET MANY PEOPLE OFF YOU BACK!!!!

     

    I KNOW THIS IS NOT ALL OF THE PROBLEMS WITH iOS 6, BUT THIS IS A HUGE PROBLEM NOT BEING ABLE TO SURF OR GET DATA THE iOS 6 DEVICE IS REQUESTING!!!!!

    FWIW, as I figured, a complete factory reset via itunes did absolutely nothing to fix the slow wifi.

    Syed117, if you lost connectivity on both your devices for five minutes, it most likely was ...RF interference!

    cmweber, there is no WPA2 over TKIP, only WPA over TKIP and, in any case, WPA over TKIP encryption has been cracked (using an app that runs on a stock PC's GPU chip --I'm sure "Life Hacker" has some kind of article on how to).  You'll want to use only WPA2 with AES wherever possible.  Also, this issue manifests itself when the iPhone's WiFi PHY circuit is kept powered up for a sustained period of time (which generates heat) --that's why web surfing to sites like this (that transfer only short bursts of data) wont trigger the problem but enabling WPA2+AES encryption and transfering large files (like app downloads, videos and speed tests) will.  The normal speed of the WiFi link also is a factor --for example, if you have a 100Mbps link (i don't know, maybe a FiOS circuit or you live in one of the fancy areas rebuilt with our American cash after WWII) or perhaps a 30Mbps link (inside an Apple Store), then transfering a large binary will only keep the PHY powered-up for a short period of time, but transfer that same file on a typical California DSL circuit (5Mbps on a good day) and the PHY will be burning energy like crazy and the problem is more likely to manifest.

    Wow - the problem is baffling.  Look at these test results:

     

    2 iphone 5's both with slow wifi.

     

    2 home wifi AP's, both Cisco, diff models, same settings. (WPA personal, AES, mixed mode, wide band, 2.4 Ghz.

     

    Both phones are slow on AP1 which has a VPN built on the AP to the US (I live in Singapore), but other devices (such as iphone 4) go really fast through AP 1.

     

    AP2 has no VPN and is straight out to the Internet.  All devices, including both iphone 5's go fast through AP2.

     

    If I setup a PPTP or L2TP VPN on my idevices directly, while going through AP2, both iPhone 5's are super slow again, and the Iphone 4 and any other device goes really fast.

     

    The commonality here is encryption.  I can't make sense of why the iPhone 5's go slow through AP1 with the VPN tunnel on the AP, since the iPhone 5 shouldn't even know about that tunnel.  But its REALLY odd, that when I build the VPN on Iphone 5 the connection crawls.  Its not the VPN b/c it works great on iphone 4.  Aple really f'd this up.

    ****POSSIBLE TEMPORARY FIX, for those with slow speeds who tried all the other stuff. I doubt it would work for the connection issue.

     

    I never had the issue with connecting to my wifi. Just that it would loose wifi at a lot shorter of a range then my other

    devices. And painfully slow wifi(lowest I got was .38 Mbps down and .5 Mbps up, *****!). Idk why I tried this(so weird), but I just deleted all the emails I had hooked up on the phone. And reset network settings and "renewed lease" on my wifi once I reconnected. Idk if all that's necessary, I'm just explaining step by step what I did. And I am now getting download speeds consistently between 20-28 Mbps down and 2.0-2.8 Mbps up in my room(relatively close to the router, but I was having issues prior). Done a bunch of speed tests and it seems to be holding up. And the areas in my house i was loosing wifi and it was even slower, are now much better. Probably could still be a little better, but they're better none the less. But maybe some other people might wanna try this. If it doesn't work, it's easy enough to add the emails back. Also I wouldnt say this is a permanent fix, because I want my emails on my phone. But helps out while waiting on Apple to get this fixed, as for me atleast it seems to be a software glitch or something. Hope it works! ;)

     

    *note- I tried every other thing suggested on here or anywhere else. Besides changing router settings, because you shouldn't have to do that. This is the only thing that worked for me so far.

    WHOA....J-figz....all I did was reset network settings...that's ALL.  And it DID work....but only for a little bit.  Now I'm back down to my crappy speed tests.  this just kind of proves that it's all software though right??

    I tried just resetting. Just "renewing lease". Reset my router. Hard reboot my phone. And other stupid things. I think it's the weirdest thing ever. But it's still working for me.

    hmmmm mine seems to be going fast on and off now...definitely better than it was.  It's not consistent at all, but I'm finally reaching 20 mbps here and there...wasn't getting over 1 before the network reset.  Thanks for the heads up
