    no it has nothing to do with access points or any of that bs.

    we all need to stop pretending that apple didnt mess up here. This is 100% undoubtedly iOS4. stop even posting that it could be anything else. we need to think of real ways to fix this, or try and get apple to fix it by seeing how many people are affected.

    iOS4 is horrible, wish i didnt upgrade

    It has to be the new operating system. I just got a new 3GS 2 weeks ago and it worked perfectly on wifi until I upgraded. Now it just says no Wifi and no Bluetooth with no option to do anything...not even search for any. The selection is just greyed out.

    Fixed my 3Gs by taping the blue > to the right of my network name and then tapping forget network settings then backed out, came back in and rejoined with no issues.

    I had no WiFi signal under iOS 4 for my 3G, 3G[S] or new iPhone 4. I solved the problem by changing my airport extreme security from "WPA/WPA2 Personal" to just "WPA2 Personal". Now all get the WiFi signal without problems.

    My symptoms were that I could join the network under settings, and it showed a fill strength WiFi signal there, but not in the status bar, just "airport mode" or 3G. And all applications failed to see the WiFi connection, either using the telco 3G connection or failing saying there was no Internet Connection.

    After the change to the base station security all worked as expected and WiFi was again available to applications.

    I just noticed something interesting. I have a iPhone 3G that had no issues with wireless until I upgraded to OS4 2 days ago.

    Symptom is that I can't connect to any wireless networks anymore. I used to see 3 or 4 networks from my location at home but now I don't see any of them anymore. I can only see one network that I can't connect to this one because its not mine and is encrypted as it should be.

    However, I was trying to figure out what is special about this network that allows me to at least see it from the iPhone when I can't see my own network with my iPhone sitting right on top of it. (Tried both my 2wire and a siemans se567).

    Using my laptop to investigate, the network I can see is an 802.11n network. All of the other networks in my neighborhood are 802.11 b/g.

    Checking the specs of iPhone 3G and 3Gs, they only support 802.11b/g, while the IPhone 4 now supports 802.11n.

    Do you think somehow the new firmware is attempting to enable 802.11n and the hardware doesn't support it?

    Apple really need to sort this out with an update in the next week or something, it can't be that difficult to fix, surely just a messed up line of code somewhere.

    i am having the complete opposite, wifi works great in fact thats the only internet i get. 3G is not working, i was curious to see how fast my 3G was so i turned off WIFI, server not reponding to all websites, meaning my 3G is not working for data, calls are ok. SMS are ok. Atleast i think they are. ANyone else having this issue, and how did they fix?

    I had this problem and a router reboot resolved it. Simple power off and back on. Has everyone tried that?
  • Chromisdesigns Level 1 Level 1 (0 points)
    there is a known problem with WIFI access after a 4.0 upgrade on at least some older iPhones. See this thread for a workaround:

    same thing here, Wifi is just greyed out since the iOS4 upgrade on a 3GS. I wish I didn't install it. Tried several power ups but nothing. waiting for a patch from apple before I reset to factory settings hoping it will fix the issue.
  • Wrinkly Pea Level 1 Level 1 (0 points)
    Reset to factory setting doesn't solve the issue. At least it didn't on my 3GS. I went to T-Mobile this afternoon. They said that the issue is known and a patch will be ready soon. The same that they told me few days ago on the phone. This time they claimed the patch was going to be released today. As you can see no patch. So I start believing that they don't know that much either. They probably just want to reassure clients. I asked for a replacement - given that the majority of other 3GSs is not affected by the same problem. They offered me to send it back for a check and repair but I had to stay 2 weeks without the phone. I'll wait few days more and then if Apple doesn't release anything I'll probably do it. I cannot stay without Wi-Fi for so long!

    Bad news. I just downgraded my iPhone back to 3.1.2 which is what I was using without issue prior to upgrading to OS4 two days ago. Even after the downgrade, the wifi is still not working. Now I am worried that the OS4 firmware may have actually damaged the wifi hardware.

    iOS4 is awful. I have the same WiFi issue. C'mon guys, what is this? Open mic night for Apple programmers? Amateur hour? What happened to the WiFi icon and what are you going to do to fix it? You're becomming more like Microsoft all the time with your janky programming.

    I have a 3GS with the new ios4 and first I thought something was wrong with my phone. Phone calls are not even ringing through, even when I call myself from a land line. I have hard reset the iPhone to no avail, turned off blue tooth, wifi and then I see the phone go from a 3G connection to an E (edge) connection, and I finally get a notification I have a voice mail waiting. Then I retrieve the message, and I think it now will continue to work. I watch the E disappear and then it goes into a continuous searching for a signal.

    Mind you this is the same location, my home, where I have used my phone for years at and never had a problem. Also, bear in mind my connectivity over WiFi on my iPad and Macbook Pro are working fine. Welcome to the Beta Test. FYI I have always had a hard plastic cover on my iPhone, so its not my hand to an antenna or anything like that.

    This is the suck.

    Hi,
    I experience the total loss of Wifi capabilities too. Here are my current investigations:
