About a week ago my iPhone 5 started acting strangely with my home network. It appears to have stopped joining the WiFi network (my network connectivity has dropped to 3G/LTE with the expected latency and my battery life has suffered as you’d expect).
Oddly, while it doesn’t show the WiFi icon in the top bar it still shows the WiFi network as selected in one settings screen.
Though on the next settings screen it just spins and never shows the checkmark (and I can’t click the arrow to see the IP address, etc.).
.
Even more curious, while the iPhone doesn’t appear to be on the WiFi network it can still AirPlay to the AppleTVs on the network. I have no idea how.
I’ve tried rebooting the iPhone and router; “forgetting” the networks and re-adding them to the iPhone. None of our other iOS devices (including another iPhone 5) have this problem. Has anyone ever seen something like this before? Tips? Suggestions?
UPDATE: See follow-up/solution here.
@alexkingorg can you post screenshots of the wifi network details, including the proxy settings?
@HiroProt The wifi network details on the iPhone or router? I’ve never set a proxy on either to my knowledge. http://d.pr/i/GvTN
@alexkingorg yeah, that screen…when you scroll further down, is there a proxy set?
@HiroProt Nope – it’s set to “Off”.
@alexkingorg okay, 2 things to try: on your iPhone’s settings, reset, reset network settings
@alexkingorg and/or hook it up to Xcode and see what the iPhone log says
@alexkingorg this has happened to me in the past when i set a proxy for testing and then forget to clear it
@alexkingorg did u try to reset the network settings?
@gamerz @HiroProt Thanks, I didn’t know about Reset Network Settings. Unfortunately, no joy (situation unchanged). I’ll try the logs next.
I recently had a similar problem where the WiFi was dropping off when the phone was asleep. There is a fix that requires you to perform a series of steps that involve turning off cellular data, rebooting, wifi, reboot, etc…. Unfortunately, I can’t find the link to the page. There is something definitely hinkey going on.
