    I have the same issue - painfully slow wifi on my new iphone5.  If i want to do anything I have to shut wifi off...

     

    The speedtest.net below shows most of the story - the first test was done with wifi, the middle two over 2 bar ATT LTE connection and the last again with wifi. There is a major issue sending data requests out (0.01-0.02 MBPS!!???).  Also, the test only shows the peak download speed.  In wifi mode, the download speed would drop to zero for most of the test.  Download the speedtest.net app and try yourself.  FIX THIS ISSUE APPLE.

    SanJoseShark, i have same wi-fi upload issue but not that bad. I wanna know how far is your iphone from the AP/router ?

    I did some test on the distance and signal strength and same 0.01Mbps upload result when i set the signal strength of the AP to a very low level.

    I am 10 feet away from the router with full connection.  After reading through the blog, I tried a solution which appears to be working:  I reset the network settings. Go to settings-general-reset-reset network settings.  Not sure why it worked as my phone is 1 mo old but subsequent tests with speedtest were successful!! You may want to give it a shot.

    For me, I've tried to work around modem&router for 3-4 days but it still can't connect to WPA2 network and even it can connected with other security. It always got slow network when we have more than five iDevices in the network. Anyway it still work perfectly at my office.

     

    the way to fix this issue is !! Replace a new iphone5 Only!! right now, my new iPhone5 is work perfectly with any network

    Drainlife, please tell us your new iphone's wi-fi chip source? Intel? Can it run on pure 802.11n network and up to 150Mbps in speed?

    I'd just like to remind people who may not have read through this thread completely, that there are no intel chips, all mac addresses were apple's. Mac addresses are assigned to companies by xx:yy:zz. the xx and yy are the same for some intel and apple mac addresses but the zz made them all apple. intel has a different set of zz which are not found on any iphone.

    So I went to an apple store yesterday for a replacement and they refused and told me I needed to speak to a senior engineer. My first senior engineer decided to ignore me for a couple of weeks once replacement number 3 didn't solve the issue but today I was helped by a new tier 2 engineer and he was amazing! He said as I'd tried the phone on a selection of routers it was clearly the phone so he's booked me an appointment to go back to the store on Sunday for iPhone number 4. Ill let you all know if it works!:)

    hi all im in uk on iphone 5 handset and on orange network. i never thought my 3g internet would be so fast and my wifi at home i struggle to connect to.funny thing is at all my freinds houses where i have connected before it works fine there.my flat mate has a google phone and uses wifi and no issues at all.

    weve changed settings on the home router and still no joy.

    James did you try two things:

    1. set the router to support 802.11bg (my iphone5 can't run on pure 802.11n)

    2. set encryption from WPA2 AES to WPA TKIP or WEP or no security

    My iphone 5 works on my work wifi flawless but not at home.  I was running a Linksys WRT120N router.  When I am at home my wifi works great with my iphone 5 as long as I am in the same room with the router.  When I go into another room the wifi signal drops from 3 bars to 2 bars and my data rates go way down to 0.5 Mbps and less. 

     

    I tried every trick out there - resetting the network settings on the iphone, resetting the router, changing the security from WPA2 to WPA, changing the SSID, manual DNS to 8.8.8.8, clearing cache and history on Safari on iphone, you name it.  I was getting no results.

     

    I decided to replace my router since I knew my iphone 5 would connect to the wifi and was fast enough if I was next to the router.  I replaced my Linksys router with a Netgear WNDR3700 N600 Wireless Dual Band Gigabit Router and problem solved.  Anywhere in my house I'm getting 30+ Mbps down.  The radio in the Linksys must have been bad or not strong enough to broadcast more than a room away. 

     

    Cheers

    Same problem here. I just took it out of the box. Wifi works great back home although I have to restart it sometimes but not at work. Connection with the 'work' network is no problem but zero or intermittent data...

    EXCHANGING MY PHONE SOLVED THE PROBLEM!!

     

    I bought the iPhone 5 on Sat Nov. 24, and since I got it I was having problems with wifi. I tried a lot of the things suggested on this thread but it did not help the slow, intermitent wifi.  I tried changing my rounter's security protocol, resetting my iphone's network setting, and even resetting my phone to factory setting and nothing worked. So I exchanged my phone, and my replacement Iphone 5 has NO wifi problems.  I've had the replacement iphone 5 for almost 2 days now and I get great wi-fi performance everywhere I've gone.  After having gone through this wi-fi headache with my original iphone 5, I am now convinced that this is a hardware issue with the iphone 5, and it has nothing to do with rounter settings, at least if your problems coinside with mine. 

     

    The problems I was having with my original iPhone 5 were the following:

     

    - Would take a long time to find any wireless networks most everywhre I went.

    - Any weaker signals would not even be picked up by my phone.  At Starbucks, McDonalds, and other cafes a lot of times it would search for wireless networks but would never find one. 

    - If a strong enough wifi network was found by my phone, and it was able to connect to it the connection would be intermitent.  The signal would jump from 1 to 2 to 3 bars randomly, and often I would lose connection altogether and my phone would revert to cellular data.

    - At home I discovered that if I stood directly next to my wireless router I would get a solid wifi connection on my iPhone 5, and I would be consistent 20Mb/sec download and upload speeds.  But, as soon as I stepped out of a 6 or so feet radius from my wireless router my connection would go to crap as described above.

    -It seemed like I had to be within a few feet from the wi-fi rounter to be able to have a good connection.  Otherwise connection would be intermitent, and speed would be very slow.

     

    Since I exchanged my iPhone, the new one:

    - Picks up many more wi-fi networks, even the weaker signals.

    - Connection is solid and stable.

    - At home I get 3 bars wi-fi anywhere in the house, and speeds at 20/mbs+ consistenly.

     

     

    If anyone has any questions I'd be happy to answer, but I recommend you exchange your phones before the grace period expires.

    I'll be curious if this change lasts. The main router at home I have been having problems with since mine began is a netgear wndr3700. It seems for most people any change clears up problems for a while and then they start to creep back.
