I have to switch off cellular data when I'm at home - even though I have wifi - otherwise the phone automatically uses data from my Optus plan.


I've gone through all the steps to reduce data leakage but it's not just leakage - it's all the data use. For example, when I watched a few youtube clips, it had drained 90MB.


I've discussed this with Optus reps a number of times to no avail. They say it's an Apple issue.


I've seen other threads discussing this, but I'm just wondering whether there's an update or a fix anywhere in sight.


It's mighty frustrating!

iPhone 5, iOS 6.0.2

    You may have a problem with your WiFi network if your iPhone can't stay connected to it.


    If you are having WiFi problems it is necessary to isolate whether the problem is with your network or your iPhone. Note: Do NOT consider your network to be blameless if some other devices can connect to it.


    First, test your iPhone on some other networks: a friend's, Starbucks, Barnes & Noble, etc.


    If it works well there then the problem is with your network. Try restarting your router by removing power for 30 seconds. If that does not help check for a firmware update for your router. If none exists which corrects the problem consider replacing the router.


    If your iPhone does not function well on other networks it possibly has a hardware problem. Contact Apple Support or visit an Apple store for evaluation. They can provide a replacement if your iPhone is bad.


    If you need more help please give the make, model, and version of your WiFi router and how you have it configured.

    I have an iPhone 5 and I don't have any WiFi problems at all as do almost all other iPhone users. You do realize that there are at least 50,000,000 iPhone 5s out there now? Do you think that all of them can't use WiFi? As I said above - Note: Do NOT consider your network to be blameless if some other devices can connect to it.


    If you assume that some things just can't be the cause of a problem then you won't have much success in solving problems. You might have a bad iPhone 5, but, if so, the technique I suggested above will reveal that and you can get it replaced.


    Regarding what you read on the internet recall this:

    Never have i heard it said better than above.


    As JimHdk has said, Isolation and troubleshooting are necessary.






    And the good old rule of the internet applies here.


    If you type into google: Problems with iPhone 5, you're gonna find people whingeing about the iPhone 5
    If you search: iPhone 5 is amazing, you're gonna find people who love it.
