Strangest thing...! I work from home so cannot test elsewhere (and live far from neighbors). Our home has (2) iPhones, (1) iPad, (1) MBP, and (1) Mac Mini. The mini is wired to our router but everything else uses WiFi.
Whenever my iPhone is connected to Wifi the internet goes down for everything. But it's only my iphone, all our other devices operate normally.
I've tried restarting iPhone, restarting router/modem, calling CenturyLink, and restarting computers. I've ever tried freezing my iPhone (desperate measure after searching online and finding that strange remedy).
Does anyone know what could be up? My ISP is CenturyLink and I am setup using a pair-bond. I believe it's DSL, whatever the phone line setup is.)
Anyone have any idea!!?
What's probably happening is that your iPhone is uploading your photo/video library to your cloud service of choice once your phone jumps on Wi-Fi. If your internet connection has limited upstream bandwidth (which, being CenturyLink, it probably does), the upstream link is likely being saturated to the point that no other traffic is able to reliably go out from your network while the photo/video upload is happening.
If this is, in fact, the problem, the only solutions are:
1.) See if the cloud service you're uploading to allows you to limit the amount of upstream bandwidth that is allowed to be used (usually a setting in Preferences in the software if the feature exists). Apple Photos does not offer a feature like this when uploading photos and videos to iCloud, unfortunately.
2.) Get a router that supports QoS (Quality of Service) and configure QoS so that no one device can monopolize your entire connection either in the upstream or downstream direction
3.) Manually pause the uploading of files to the cloud until such time as that is the only thing that is happening on your network (i.e. when everyone in the house is sleeping).
I chose to do the third option a few years ago when I was using AirPort Extremes as my routers (which do not support QoS) and my ISP was Charter (which offered 100 Mbps downstream but only 5 Mbps upstream). Apple Photos was uploading my 15,000+ file photo and video library up to the cloud via a measly 5 Mbps upstream connection. Not only did it take forever, but Photos maxed out the upstream bandwidth such that no other device on my network (wired or wireless) was able to send requests out to the internet reliably at all.

Edit: I just reread your post. I'm not sure I understood what you were saying. When you said, "But it's only my iPhone, all our other devices operate normally", did you mean that only your iPhone cannot go anywhere online when it's connected to your home Wi-Fi but all other devices on your network work fine when your iPhone is connected to the Wi-Fi network OR did you mean that the problem occurs on your entire network but it only occurs when your iPhone is connected to the network?
I assumed you meant the latter. If you meant the former, I would check to make sure you don't have a proxy server specified on your iPhone. To do this, go to Settings --> Wi-Fi --> tap the "i" next to your Wi-Fi network. HTTP Proxy should be set to "Off".
