While your iPhone or iPad should have no issues connecting to Wi-Fi or holding on to a strong signal, issues do arise from time to time. Under iOS 6 many users have been experiencing Wi-Fi connectivity issues. Symptoms have ranged from no signal, to pages not loading within Safari, or the inability to connect to a network.
If you're experiencing any of these issues, follow along for a few tips of correcting network issues.
Forgetting a network and re-joining it can sometimes kick out bad Wi-Fi settings and allow you to connect normally again. It's the quickest way to see if your issue will correct itself or if you need to explore the problem further.
That's it. Open Safari or another app that requires web access to be sure that you now have network connectivity. If you don't, move on to the next section. If you do, that's as far as you need to go.
If you're still having issues after re-connecting to your network of choice and you are sure it isn't your router or home network, resetting all your network settings may solve the issues. You won't lose any media or content except for networking settings. This means you'll have to re-enter logins and Wi-Fi passwords as they'll be completely cleared.
Once your device reboots, try connecting to a Wi-Fi network again to see if the wireless connectivity issues have been resolved. If not, continue on to the next step. If Wi-Fi is once again functioning properly, you don't need to continue on.
If issues keep persisting, it's a good idea to do a complete software restore to rule out any remaining software issues. If you aren't sure how to completely back up and restore your device, you can check out our guides on how to restore using iCloud and how to restore using iTunes.
If you're still experiencing issues after attempting all of the steps above, all is not lost. If you're under warranty, we'd suggest heading to your nearest Apple store and explaining to them that you've tried all of the above steps and still experience issues with Wi-Fi connectivity. Most likely, they'll swap your device out for a new one or can troubleshoot further to figure out the root of the problem.
If you aren't under warranty and don't to pay for an out-of-warranty replacement device, it may be a good time to DIY repair it yourself. While we don't yet have guides for everything, we've already got a large amount of DIY repairs covered for iPhone 4, iPhone 4S, and more.
Check them out and see if it's something you're willing to fix on your own. If not, you can always use a mail-in service such as The Pod Drop where a repair will most likely run you a lot less than an out-of-warranty replacement from Apple and come with a warranty.
If you have a repair place by you, just make sure you're asking questions about what kind of parts they use and how long they warranty their work for before committing to using them.
