I have 2 iphone 4 both have the same problem. they wont reconnect to the wifi router even thought the icon on the phone shows that it is connected.

I check the router info, it shows that about 1 min of wifi inactivity, the iphone drops connection and wont reconnect. I have to turn the wifi off then on to get connected again. looks like the same issue Jobs had on the keynote stage.

iphon4, Mac OS X (10.6.4)

    It is not the same issue that Steve had at all.
    He was connected fine, but there were over 500 WiFI Hot Spots running in the room, people had thier own MiFi 3G devices broadcasting hundreds of WiFi base stations.

    You problem is different and as it affects both iPhones is probably related to the WiFi router.

    Have you updated the firmware on your router recently?
    How old is the router?

    The router is Buffalo WHR-G300N about 1 year old with DD WRT firmware, 10/10/09 built.

    I am having the same issue. Both my 2G and my 3GS iPhones connect to my network without a problem and they maintain the connectivity no matter what. With my iPhone 4, I cannot keep my connection for more than a minute (if that) and when it disconnects I cannot reconnect. I've reset the network settings on the phone and still no luck. It seems to work better when I am not holding the device. Sometimes it works, sometimes it doesnt. But when I am holding it in any way shape or form, with my whole hand, or just 2 fingers, nothing. I can be 2 feet away from my router, which is Apple's Time Capsule, and I still cannot connect.

    When was the last time that you guys reset the router?
  • Filipao Level 1 Level 1 (0 points)
    I reset the router on the day I got the iPhone 4 (23rd). Then again a couple times on the 24th and probably 1 or 2 times more since then (all trying to solve this issue). . Any other thoughts? Initially it was so bad that it would not connect at all. So I reset the network settings on the phone and then I was able to connect and surf for about a minute until it died again...

    If your network is secured, ensure these three things, as I've heard that they can cause issues with iPhones...

    1) Make sure your SSID is set to broadcast. This is default, so unless you changed it, it's this way. Pretty much, if you can scan with your iP and see your network, then it's fine.
    2) If it's secured, make sure it's using WPA security, and not WEP.
    3) Check to see what signal it's broadcasting on. Haven't done much research on this, but I think if it's on G, it seems to do better than N (even though the OPPOSITE should be true).

    Thanks for the reply. In terms of the things to make sure:

    1) Yes I do broadcast
    2) Yup, using WPA
    3) It is a N router so I am using the N standard since I have a mac mini server connected to it, I want to use the higher bandwidth. I'm not sure if I can tell my iPhone 4 to connect using G instead, but I definitely want to keep the N opened for the mac mini.

    I have the same problem. It will connect but then disconnects randomly. My 3GS, iPad and MacBook all stay connected no problem. I tried resetting the router, renewing the lease, resetting the network settings, nothing works. I think it's an ios 4 issue. Hopefully a fix is coming soon.
  • Filipao Level 1 Level 1 (0 points)
    Im a little hesitant to think its an iOS 4 issue since I had iOS 4 running on my 3GS for a while now (developer account). And never had any issues. Wifi on my 3GS is solid, regardless of which OS its running. I wonder if its related to the new wireless N on the iPhone 4... thats the only thing that is different in terms of wifi between the 3GS and and 4.... that and the antennas (sigh)
  • EBSkater Level 2 Level 2 (490 points)
    OH! One more thing that I forgot until reading this...

    No idea if this has anything to do with the fact that the left stainless steel band is the non-cellular antennae, but it's worth a try...

    Do you have bluetooth on? I've noticed before that since the bluetooth and WiFi (and GPS) use the same antennae, if I have bluetooth on, it messed with my WiFi, but when I turned bluetooth off, it worked okay...

    If you don't have bluetooth on, then poo, I'm fresh out of ideas... :'(
  • Filipao Level 1 Level 1 (0 points)
    I dont have it on right now. But I usually do to connect to my car. I will try the with and without and see if there is a difference. I really hope thats not the case. Or else I spent all that money on my car stereo to be able to talk hands free without an ear piece for nothing
  • NH1977 Level 1 Level 1 (10 points)
    That did the trick for me. I shut off Bluetooth and wifi stays connected now. I called Apple to ask about this and they hadn't heard of it.
  • EBSkater Level 2 Level 2 (490 points)
    It's because the bluetooth uses the same antennae as the Wi-Fi. This is a known issue, as many developers who enable multiplayer for games over Wi-Fi mention that if you're having issues, to turn off bluetooth, or vice versa.
  • Filipao Level 1 Level 1 (0 points)
    thats awful... you pretty much cant have both turned on at the same time then... that just *****
