Try doing a Hard Reset
Hold the Home button and the Power button until the white Apple logo comes up on screen. Then release the buttons.
REMEMBER! Hold the buttons until you get to the Apple logo. Do not let them go when the "swipe to turn off screen" comes up or when the screen goes black… Wait for the white Apple logo then release the buttons.
Delete your home WIFI and re setup the same WIFI again on the phone. This should allow the phone to fine tune whatever within to match your network setting.
If problem continue, send phone to Apple for WIFI diagnostic.
Turn cellular data off in settings on the iPhone but keep wifi on.
Just because the icon does not appear doesnt actually mean its not connected
As long as you have a tick next to the network in the iPhone... and the IP address is not 169.254.XXX
This does solve the issue, temporarily. But as soon as I turn Cellular Data on again, it "takes over" instead of the WiFi. This really bugs me, I don't want to keep switching the settings as I come and go... But Thanks, Caseyrose, even though it's not a fix, this does work.
EDIT: I don't know if I checked wrong the first time or what happened, but it doesn't work. With cellular data turned off, I can't even access WiFi. I'm beginning to hate this update.
maybe if you go into the iPhone settings>Wifi> Then find the name of the network>
1) Has it got a tick next to it?
2) If it does and you tap on the blue arrow> Does it have an ip address?
3) If it does what is it>
4) You can "Forget this network" or "renew lease"
How far away from the router are you?
2) It does.
3) It's 169.254.x.x. Don't know much about IPs, but isn't this the network one?
4) I can, I tried both options.
The router is in the same room as I am. That's not the problem - in the past, I could get a reception from the building's parking lot.
I've also tried resetting my network settings, as soon as I found the problem. Again, didn't work.
The links are all a bit pointless. "Make sure the router works", "turn wifi off and on again". Tried everything.
That IP Address is a self assigned IP Address...
This means.... Its not going to work.
Its not connecting properly to the router,
can any other device in the house connect to the router?
You may need to try some router troubleshooting...
There is not much more that i can suggest other than a restore as a new device and test with your home network...
That would confirm a hardware or software issue.
This must be so frustrating
It is, really frustrating. Frankly, a clean restore would really bug me - I've got lots of stuff saved on the phone, and don't want to spend hours repeating the settings. Oh well, I guess this is just something I'm going to have to live with.
You can backup your information and get it back later But for testing purposes you need to have nothing on the iPhone except for the wifi settings.
