    I've update yesterday my white iphone 5 16gb to 6.1.4, and now I can't connect to WIFI network in my company. Why was that?!

    There is any way to revert this ******* update?

    I just upgraded to iPhone 5 from iPhone 4S. 4S connected great to wifi and I had reasonable 3G coverage. I've had my iPhone 5 for 24 hours and have been unable to properly connect to wifi, my iPad had full reception while my iPhone sitting right next to it has none. As for the cellular coverage it says 'SOS' 50% of the time, and the other 50% of the time I'm lucky to have 1/4 of the full reception and cannot send messages.

    I don't know what the problems are, but the iPhone 4S worked perfectly and had no problems. I thought I was UPGRADING, not going back to 2002 mobile technology. Not an apple fan at the moment!

    I just bought my new iphone 5 and my wifi is terrible!!! God Why!!

    Now on the new iphone 5 they simply do not buffer corretly my ipad 4 works fine but the iphone not!

     

    the same connection or even others still the same problem....

    Honestly, you will most likely just be wasting your time.  The drones at the apple store know next to nothing.  Even the higher ups admit no problem exists, even after having a trouble ticket open with them for 6 months!!!  Apple is a VERY secretive company, not just about forthcoming products, but also current products and their problems. 

     

    I hate to say it, but I think the loss of Steve Jobs is already becoming a BIG problem for Apple...

    I am also having the same problem!

    In my case, an impressive thing happened. I got my iPhone5 to a local assistence listed in Apple's site, and they confirmed my iphone had an wi-fi issue. Then they triggered my warranty to Apple to replace it. For my suprise, Apple Care rejected my warranty saying that "logic serial number is differente from the intern serial number"(wtha a **** is that???). And I should send my phone directly do Apple (in Brazil) for them to analyse it personnaly.

    I did it. I had call Apple Brazil and open a case for it.

    After a couple of days after sent the phone to them, I receive in my home a NEW iphone. I became very happy with the service speed.

    The first thing I did when receive the replacement, was testing the Wi Fi, of course !

    And ---- the problem persist!!!!! How can !?!?!??

    Analysing in more details, it seems to be worse than before.

    I have an iPad and another iPHone4 and both receives perfectly the WiFi signal from my router at home, putting the iphone5 at the same position, the signal is TOO POOR, and weackness, and very instable.

     

    I am starting to think that my router can be the problem. But how can it works perfectly with other devices as iPad, iPhone4 and Blackberry....

    I Have fixed the problem that everyone is having with there IPhone 5. These are the steps that you need to fix it.      1. Log in the your router, by typing in 192.168.1.1 on your computer.

    2. Then find the info of your routers that lists the routers status and info.

    3. Find the info of your routers DNS address. Once you have found that.

    4. Go on to your phone, enter settings and then wifi. then go into the wifi to change the settings. Then once there delete the DNS that is entered in the DNS box and enter the address that you have found on your router. It worked for me.

    So a bit more information, decided to so some network sniffing, on the next hop device up from my iPhone. As far as I can make out the issue I'm facing is massive amounts of TCP Retranmissions, resulting in a ever shrinking TCP Window (down to 136 bytes, I think normal window size is 16384).

     

    I've completed this testing with iPhone 5, iPhone 4.0, iPad 2 and iPad 3.....only the iPhone 5 shows this issue (I also tested with both iCatcher and Downcast, with multiple podcast sources).

     

    So something appears broken in the iPhone 5 network stack, something that is causing TCP Retransmissions that are well excess of normal, this results in a decrease in the TCP window size, causing slow downloads.

     

    Anyone else agree with my largely un-informed explination above...........

     

    Here is a screen shot of the network capture, 205.234.175.175 is the podcast source, twit cachefly cache server & 192.168.252.64 is my iPhone 5.

    This makes a lot of sense. What the heck is up with Apple? Don't they realize the negative publicity they might get because of all these Wi-Fi problems isn't worth the money they may save by burying these types of issues? I would be happy if they would just admit ther eis a problem!

     

    Come on Apple, step up to the plate and do somthing about this before market share slips away.

    iOS 6 requires WMM compliance:

     

    Wireless Multimedia Extensions (WME), also known as Wi-Fi Multimedia (WMM), is a Wi-Fi Alliance interoperability certification, based on theIEEE 802.11e standard. It provides basic Quality of service (QoS) features to IEEE 802.11 networks. WMM prioritizes traffic according to four Access Categories (AC) - voice, video, best effort, and background. However, it does not provide guaranteed throughput. It is suitable for simple applications that require QoS, such as Voice over IP (VoIP) on Wi-Fi phones (VoWLAN).

     

    Many routers' firmware do not comply.   This is a huge part of the problem people are seeing.   I have a Wifi Ranger router in my RV.   None of my iOS 6 devices would transfer data when connected to the router, even though the connection was solid.

     

    WFR sent me a beta version of their upcoming firmware which is WMM compliant and just like that, my wifi problems disappeared!   Great connection with fast data speeds.........

    We are on Cisco wireless lan controllers and they call it WMM. We have had that turned on all along but still had problems with the dreaded unable to join network error. There seems to be more than one type of Wi-Fi problem around here. My big problem was with not obtaining an IP address via DHCP. The lan controller kept thinking I was using an address already in use by someone else. I am on my third or fourth iPhone 5 by now and they all have had problems with WI-Fi. Other iPhone 5 users in my office seem to work fine. I think I am about done with iPhones.

    My iPhone 5, when connected to my personal wpa2 secured wi fi network, works normally for web navigation but has a very bad performance when connecting and downloading apps from Apple Store.

    I hope they fix that soon.

    I thought the only problem I had was a bad performance in downloads as I reported here recently, but I soon realized that certain apps like Google Earth and Google maps, didn't open under my wpa2 secured network.

    I decided to change the security to wep as suggested by people having the same problem. It turned out that it is now functioning very well, faster than the iPhone4 that is connected to the same network.

    It seems that we must sacrifice security in order to have our top tech phone to function properly.

    I hope they fix that soon!

    Give us a link to the cover you bought. My cover makes no diff.

     

    I just got my iPhone 5 swapted out for a new one FINALLY and I went with the thinest case possible because I've been so frustrated with this whole mess.  The Agent 18 Case is  as simple as they come.  It's a thin black case and made of some kind of plastic that is easy to grip, but easy to get in and out of a pocket.  If I have another WiFi issue with this thing......I WILL NEVER COME BACK!!!!!

    This of course didn't fix the issue for me, but I do love the case
