Wi-Fi connection issues resurface with iOS 4.3.3

updated 05:10 pm EDT, Thu May 12, 2011

Connections weak, disappearing, missing

Some iOS devices are once again having trouble connecting to Wi-Fi hotspots, accounts say. Both media reports and posts on Apple's support forums indicate that after applying the iOS 4.3.3 update, an iOS device may start spontaneously dropping connections, repeatedly disconnect and reconnect, or even fail to connect at all. In some cases Wi-Fi status is misreported, or a stable link may involve staying too close to the router.

Backing the association with iOS 4.3.3 is that v4.3.1 devices can be in the same room and function normally. No permanent solution exists, although some temporary fixes may include turning Wi-Fi off and on in iOS, or resetting a device's network settings. A hard reset is another option, although in any circumstance Wi-Fi will still eventually drop.

Wi-Fi stability has been a recurring problem with iOS updates. Most famously these affected the original iPad immediately after launch, but issues have been present to different degrees as far back as 2009, and as recently as iOS 4.2.1. The current trouble affects all iOS handhelds, not just iPads.

    WiFi DropOut with 4.3.3

    Yep, count me in as to somebody with the WiFi dropOut problem. My new iPad 2 came with 4.3 and was absolutely fine. Since the 4.3.3 update (which I installed last week), for the first time I'm having sporadic dropouts, even when I'm in my office just 3 feet away from my Airport Extreme. HELLO, APPLE.....please fix this and TEST before you release updates!

    Changing from WPA2 Personal to WPA/WPA2 Personal

    I got my iPad2 yesterday it came with 4.3.2 and kept failing to re-aquire my TimeCapsule network. I found that changing the security on the TC from WPA2 Personal to WPA/WPA2 Personal helped.

    wifi personal hotspot VERY !!unreliable garbage

    I have an iphone 4 4.3.3 and have been trying to use the personal hotspot to connect to a laptop and ipod touch 4g 4.2.1 and it is totally unreliable. I get kicked off anywhere from 1 minute to 60 minutes, without auto reconnection. This happens whether I have only the ipod or the laptop connected also not only when both are connected. Both the laptop and ipod have been set to not go to sleep, so that is not the problem. I have also had a video streaming program running between the ipod and the laptop using the iphone to ensure data flow and still was disconnected.

    Both devices disconnect at the same time, so I believe it's got to be a fault with the iphone or it's software.

    I require this feature almost daily and it is not doing what it is advertised to do.

    I am disappointed in apple for releasing yet another firmware version that includes an unstable version of this feature.......... even though there are so many complaints the same as mine. We cannot be all wrong!

    Not to mention the findings from Princeton University, that also concern the wifi within IOS devices dating back as far as firmware 3.2. Seen as the personal hotspot is only DHCP I'm sure it's reasonable to presume there could be a connection.

    I did find a suggestion on the discussions board that may help but I need to do further testing to prove it. I have tested it once and had more success than the previous 60 hotspot connections, so there is promise.

    It was suggested to turn the bluetooth off on my phone so that is what I have done, and like I said above the first test appeared successful. Although I also use the bluetooth feature daily so this is certainly not a fix I wish to use continually. The second connection lasted for 8hr till i disconnected it, then the next with bluetooth back on lasted under 10 min....CONCLUSIVE FOR MY SITUATION.

    I also have a problem connecting my iphone to an ad-hoc network with my xp laptop. My ipod connects with no problem to the same network that the phone will not, what is going on? Maybe this feature is disabled due to the hotspot being added, if so it needs to be broadcasted to people. As it is we seem to have gained one feature and lost another.

    I sent everything above to apple via their feedback web page, i hope everyone else does also
