Why won't my iPhone 6 stay connected to the wi-fi?

When it says its connected it works fine. But it connects then disconnects then connects then disconnects. Auto connect is on. It doesn't do this all the time. Doesn't do it with any other devices I have. Just the iPhone.

Interference within the same channel. If your router supports 5GHz and you don't have any other devices that require 2.4 only then switch the router to 5GHz only.

If the Wi-Fi disconnects and switches to cellular data, it's likely using Wi-Fi Assist. This is a feature that makes the iPhone switch to cellular data when it thinks the Wi-Fi simply isn't strong enough. You can turn off Wi-Fi Assist in Settings > Cellular (the Wi-Fi Assist option will be on the bottom of the screen. Tap to disable). To strengthen your connection, try being closer to the router, use a less-interfered network (5 GHz), or Reset Network Settings, to try and shake off any sort of setting that may have been giving problems to your iPhone (this setting is found in Settings > General > Reset (again, this option is found on the bottom of the screen).

  • Why won't my Wi-Fi stay connected on my iPhone? Everyone in my house has an iPhone. My phone is the only phone that constantly disconnects from the Wi-Fi every 10-15 minutes. I tried resetting the network and everything.
  • Why won't my iPhone 5s connect/stay connected to my Wi-Fi? I have reset phone back to factory settings. I have reset network settings. It connects briefly then disconnects and says it can't join network. It's recently started telling me I have an incorrect password (I'm typing it correctly) Both my laptop and tv are having no problems connecting. Hopefully someone can help me out. I won't be able to go into Verizon until the weekend. And if it's something I can fix on my own, I would rather do so.
  • Why won't my iPhone 4S stay connected to Wi-Fi? Every time I'm connected to Wi-Fi and then lock my screen the Wi-Fi isn't connected anymore. So then I have to go to setting and reconnect every time. How can I stay connected to Wi-Fi even when I lock my screen.
  • My Wi-Fi on my iPhone won't stay connected for more then 2 minutes? I own an iPhone4s, The bill hasn't been paid in two months. I can't keep a page open for any longer then 2 minutes, it will then stop loading and refuses to load anything else. I try refreshing the page, the only way the page will load again is if I disconnect and reconnect my Wi-Fi. This becomes a nuisance when you have to do this at least once every minute. Anywhere else where I'm connected to Wi-Fi it is fine, it's just at home. What's wrong with it? How do I fix it?
