    Hey everyone,

    I've tried just about everything I can think of to research solutions to this problem on my own, and now I come to you.

    My iPhone has suddenly stopped picking up my WiFi at home. There have been no changes to the settings on the WiFi or on the iPhone; I first noticed it when I came home from work one day and could no longer access the internet through the WiFi.

    The issue used to be that when I went to the list of available connections under Settings -> WiFi, it would see my home network and put a nice tick next to it; however, that's where it stopped. The icon next to my network would stay that little circle that says you're connected to the mobile internet network, or occasionally 3G (I live in a rural area with very spotty 3G coverage), instead of switching to the WiFi symbol. I'd also get speeds and use up my data allowance while browsing the internet.

    I tried turning off mobile data, which results in the WiFi symbol appearing next to my network, but when I try to view a webpage in Safari I get the message that "Safari cannot open this webpage because it is not connected to the internet".

    Since this problem began, a new and more worrying issue has developed: my mobile internet and phone reception seem to be failing as well. If I turn off my mobile data and the image in the top corner shows that I'm connected by the WiFi, my signal strength suddenly drops to one bar, when I normally get 2 or 3 at home. I also completely lose the ability to make calls (though again, this was a fairly inconsistent ability to start with as every call I ever made since about one month after buying the phone would return 'Call Failed' even if I was in an area with full signal strength) and send texts (an ability I have never lost before).

    When my mobile data is turned on, it waves in and out of actually picking anything up. Sometimes I have zero signal strength but a 3G connection (still can't open any web pages).

    Any ideas? I'm leaning towards a hardware malfunction given how quickly this problem came about. I have never dropped my iPhone, or tried to test if it is waterproof, so I don't yet think this is my fault.

    Seems to be your having a few problems, it is definitely a hardware fault, since your home Wi-Fi is working correctly, and 3G signals seem to drop, including the ability to receive calls. Try updating your software via iTunes, if all else seems to fail, contact Apple or go to a genius bar for more information.

    Try reseting your home broadband, or turning your iPhone off and on again.

    Turning it off and on again was the first thing I tried. No luck.

    Software is updated, it's running 4.3.2. The problem remains. It's not jailbroken and it's less than a year old so I think it's still in warranty, but I'll have to find all the documents and everything.

    Do you have a wifi hotspot you can try to make sure it's not your home wifi causing the problem?

    The OP is stating that the phone's experiencing reception and 3G connection issues as well - so even if the Wi-Fi is working correctly, it would leave other key problems unfixed.

    Yeah and he's jb and changing settings. He needs to narrow down the issues, which is why I wrote what I did.

    Why is it assumed that its a hardware fault?

    Many factors could show this having affected BOTH 3G and WLAN.

    1. Just noticed it back home 1 day.
    - Go into Settings and FORGET this network. use your Mac/PC to goto Http://192.168.0.1 and logon with admin id/pw to the router.
    Check your WLAN settings - especially the password used to connect.
    * is your wlan network broadcasting? VERY important.
    After resetting the WLAN password retry to connect the iphone as if it was the first time. Test the internet connection.

    PS: if you cannot get into the router from a Mac/PC and you KNOW that 192.168.0.1 was NOT changed to something else on the router for access - then RESET your router as someone probably figured out the default pw to it.

    2. 3G … network congestion could affect this and also maintenance work (call your provider to inquire). Simplest solution is to try 3G anywhere else … if that doesn't work, FULLY power off the iPhone wait 5mins and power it back on again ~ turn off WLAN and test your 3G connection.

    Try the troubleshooting before assuming its a hardware issue and wasting time going into an Apple store doing a return and wasting Apple's costs for doing that.

    Cheers.


    EDIT:


    being connected doesn't mean you're getting internet; think of it as an on-ramp to the highway yet the merge is closed. Tap on the arrow next to your wlan connection on the iPhone and it SHOULD show you an IP address & a default gateway. IF no default gateway then the on-ramp merge is closed.

    I don't have any access to the WLAN, it's set up and maintained by my dad, but we've sat down and tried to address this and neither of us can come up with a solution. It's all up and broadcasting, and my dad's iPhone is still connected.

    It doesn't get 3G even 40 miles from my home in the middle of a town, and it was fully powered off for 8 hours last night.

    Wasting Apple's costs? They're a multi-billion dollar company and, being a profit-making business, they're not going to do a return out of the goodness of their hearts, they're only going to do it if they cannot prove that I've somehow voided the warranty. If they do a return then a return was definitely needed; if not, a return was still probably needed.

    Now this is interesting; I don't appear to have a default gateway, or at least not one that I can see. There isn't even a box for it. Where do I find the default gateway on my settings?

    Prom1, your over complicating the issue and by the way, why would you say that you will be wasting costs if the iPhone is taken to an Apple retail store for repair? They are a huge company and the customer has the right to get their product fixed if it has an issue not related to a user fault. If the product is still under warranty, why would you pay any costs to get a repair for it?

    And, I don't think it's to do with settings, remember the OP said it suddenly stopped working, so settings were fine in the first place, there seems to be something affecting it. I had this specific issue with my iPhone 4 as well (where I would have troubles accessing my 3G outside even in highly populated city centres and couldn't receive calls for some time)... and it fixed itself after a week or so - don't quote me on this as I have no idea how.

    If your Wi-Fi is working normal, then thats not the issue. I would definitely think it is a hardware fault, so best to just wait a couple of days, as mine was automatically fixed (no idea how), if all else fails, then go to an Apple retail store - they are the "geniuses".
