    I just found this thread because my Verizon iPhone 5 has a problem with highly inconsistent WiFi connection to my home router (Airport Extreme). Normally I get download speeds of 30 - 50 Mbps (Time Warner Ultimate cable internet). But, suddenly and for no reason, I was getting less than 1 Mbps on my iPhone. At the same time, I was getting 40 Mbps on my Macbook Pro and 30 Mbps on my iPad. So I rebooted my iPhone and now am getting about 50 Mbps again. But why does this happen and why such a huge difference? Upload speed does not change (stays around 3 - 5 Mbps).

    Same problem here: Since the update for iOS 6.0.2 with my iPhone 5 64GB wlan connectivity is very bad. Full wlan (near router) but no data came to the iPhone.

     

    Before iOS 6.0.2 i haven't any problems with wlan...Apple *** you doing last time?

    Hi Katie

     

    The bad news is that 10 minutes later the wifi issue happened again.

     

    The good news is that I have tried someting else now which appears to have worked and has been working at great speed since last night.

     

    I don't know which of these worked so might be worth doing both...

     

    1: - Turned my HTTP PROXY on my phone from Off to Auto

    2: - Selected a new channel for my Wifi from the router (from channel 11 to channel 6 on my bt homehub)

     

    Since then I have had no problems and the speed of loading and downloading is pretty impressive.

     

    Good luck and hope you can fix the issue which does appear to be a software issue on the phones which hopfeully Apple will sort out soon, but in the meatime try the above.

     

    Thanks

    I picked up an iPhone 5 yesterday--my first iPhone.  I'm experiencing wifi issues, but they seem to be with receiving the wifi signal.  My home office is where my router is located, and my desk is approximately 5 feet from the router.  While I can connect and data seems to move okay, I've noticed that the signal will vary quite a bit.  Meanwhile my iPad 2 maintains a strong signal.  Router signal on the iPhone jumps up and down even when the phone is placed next to the router.

     

    When I go to the next room and am approx. 20 feet from the router, the signal quickly disappears, and I lose wifi connectivity.  Still, my iPad and Macbook Pro are maintaining good signal strength at these locations.  So, it seems to be a problem with reception.  I will try later today at a place with public wifi to see how that works. 

     

    Is this what the hardware problem is--poor reception?  And will an exchange for a different iPhone possibly cure this?

    Hi don_toronto

     

    Do you know if you are running with WPA2 with 802.11n or 802.11g?

     

    With 5GHz or 2.4GHz?  If you can get WPA2 with AES to work that should be the fastest mode and 5GHz channels are generally the least congested (but have the sortest transmission distance) if you are competing for bandwidth with a lot of other access points. WPA2 does give more secure authentication but is less comptable with older access points running older firmware.

     

    On my iPhone 5 setting the access point to have two different SSID names for the two frequency bands. Using WPA with AES and telling the iPhone to forget the SSID on the 2.4 frequency band gave me rock solid performance.

    Where I live there are 50 SSIDs visible on the 2.4 GHz band so the data transmission collisions are high resulting in degraded performance.

     

    I'm running IOS 6.0.2. and looking forward to a more robust WiFi driver, especially one that will go back up in speed when transmission conditions permit. The current driver will drop in speed if there is interference and not go back up to full speed automatically unless you reset WiFi. You can reset wifi by turning WiFi off then back on in the phone, or move from no to auto proxy or back of change the access point from one channel to another, etc. the problem is that you often get back to slow speeds when interference causes transmission problems because the phone doesn't recover back to full speed after the interference passes.

    Well, after numerous resets/restores on my router and iPhone, it seems like everything is working as it should be. I'm getting better results on the Speedtest.net iOS App and more importantly, I just downloaded an entire album from iTunes in just around a minute which is what I'd expect.

     

    I'm using an AirPort Extreme Router - 5th Generation Dual band with 7.6.1 firmware. I have the wireless mode and channels set to automatic, security at WPA2 (AES by default - no way to change it even if I wanted to). The only thing I've changed and I don't know that it's making any difference is I'm using OpenDNS' DNS servers instead of my ISP's (Charter Cable) default. Using the AirPort iOS Utility, I've seen that I've been connected to both the 2.4GHz band and 5GHz bands and both seem to be working quickly (note: I do NOT have a separate SSID for my 5GHz band).

     

    If there's anything I've learned on this forum - there are no silver bullet fixes nor are there necessarily any solid/consistent methods for testing. For anyone using Speedtest.net - I wouldn't necessarily use that as your standard. Try downloading some songs from your iCloud account (assuming you have some) from iTunes and see how quickly they download. Or try some Podcasts (althought I kind of detest the Podcast App). I think that's a pretty objective test to see how well those things download. As many have pointed out, this is a complex issue between iOS software, iPhone hardware, router brands and firmware, etc.

    For what it's worth I found this interesting.

     

    I posted about a month ago when I first got the i5 I was loosing my home wifi connection.  At that time I noticed the phone did not resolved the DNS addresses but used the routers IP address as the DNS address. I manually entered the three addresses, separated with commas.  Since then I have not lost connection.

     

     

    Today I browsed to the router via the phone.  To my surprise the DNS addresses, 1-3 were blank.  When I tapped on any of the 3 blank spaces the address appeared and a flag popped up asking if I wanted to dial that address.  I went to my pc and browsed to the router, all three DNS addresses were there.

    My wifi has an i4 that connects to our home internet just fine (WPA)

    I have an iphone 5 that my work provided, tried to connect it to my wifi at home and it didnt work.   Thought it was a problem with our home wifi or some compatibility issue with the i5 or 6.0.1 ios. 

    My son just got an i5 & has 6.0.1 on it, didnt think it would connect to our home wifi, but it did no problem.  My wife and doughter both got ipad minis, both of those also connect to our home wifi fine.   My son has updated to 6.0.2 and still no problems.


    So the issue has nothing to do with IOS version, or our home wireless.  Seems to be a Iphone issue...

    We can't say it's a hardware issue, unless it happens always on the entire line.

     

    My case proves it is not a hardware issue: my iPhone 5 on 6.0.1 worked perfectly until one day it stopped working on seemingly 802.11n inside my home and WPA2 secured networks outside my home.

     

    It worked, now it doesn't. It's not a hardware issue and an update wasn't the cause of it's demise. Something in the software just isn't resolving well.

    Serious improvement with my black 32gb iphone on 6.0.2 finding networks & data transfer when taking off aluminum case Ringke SLIM.

    I'm in a hotel... with the case it doesn't see any networks, when I take off the case it sees 2 different networks.

    Also the data transfer is unparalleled.

    But it still looses connection when the screen goes to sleep....

    I disagree. From what I have seen and through my own experiences, I truly believe that it is a hardware issue that can sometimes be compensated for by software. Those with extremely poor hardware still suffer with the best of software fixes.

    Marchall,in your router config you should have a tick box to have the router be the DNS server or not. So what happens is if the router is being used as DNS, the devices will have the routers IP address as the dns server so the requests will be for the router to do the "lookup" which in turn used the ISP's DNS. Its been recommended for general WIFI connectivity( not just Apple decives) to bypass the router and have the ISP's DNS be used. So unticking the option will make all your devices (laptops, idevices,etc) to get the ISP's DNS instead of router IP address. This is typically in the network settings. That option may resolve your particular issue so DHCP will give you the ISP DNS servers instead of the routers IP.  It Excerpt from DLINK

    <<<DNS Relay

    When DNS Relay is enabled, the router plays the role of a DNS server. DNS requests sent to the router are forwarded to the ISP's DNS server. >>>>>

    Two iPhone 3gs' work just fine With various different Airport Extreme (gen 2) settings.

    One iPhone 3gs is iOS 3.1.3! The other is iOS 5. The ipad mini with iOS 6.0.2 works fine.

    Two 2007/08 MacBook Pro's find wifi fine. ALL aforementioned get 3 bars signal at about

    75mbps avg. Two iPhone 5's have had nothing but problems since Dec 18/2012 -when we both

    updated to iOS 6.0.2. Dropping connections, can't find wifi/network

    etc.

    We both are sick and tired of (having paid alot of money and then) having to do Apple's dirty

    work/labor because they don't practice due diligence. 199 pages shows that this is a serious

    problem-  hardware or software related! Apple should be more transparent and admit they

    have screwed things up! WE should get paid by them or at least get some sort of rebate

    voucher or credit for having to suffer with their mistakes repeatedly. Everyone has to either

    go to vendor, call Applecare (if they have it) and generally waste their valuable time after

    having paid good coin for one of Apple's products and then who gets the MEGA profit and

    who gets stuck dealing with cleaning up the mess when Apple screws up?

    SMARTEN UP APPLE!

    The lack of a back button on info page at the Appstore is a prime example if the Apple ineptitude.

    How many years has it been a problem? Exactly...a few years now. 

    Come on, seriously. Do you even read these complaints, Apple? Terrible.         

    iPhone 5, iOS 6.0.2
