New IPhone 7 crashes WIFI signal

I'm experiencing the exact same problem. I received my new iPhone 7 two nights ago and connected it to my home WiFi network before bed. I had planned for all of my apps and iCloud photos to download while I slept. I woke up the next morning and my phone was connected to LTE. As I was no longer connected to WiFi, I used up my entire data allotment in one night! Thankfully, Verizon recognized that my data usage was abnormal for one day and restored it.

I have experimented with the Wifi connectivity issues and here is what I have discovered:

1. If my iPhone 7 is the only device connected to the WiFi network, I usually remain connected. However, the signal drops periodically.

2. If my iPhone 7 joins the WiFi network with my MacBook Pro and/or iPad Mini, the signal drops on all devices almost immediately.

3. If the signal drops on my MacBook Pro or iPad Mini, the only way to restore the signal is to turn off Wifi on the iPhone 7.

I was so distraught by the above turn of events that I ordered a new cable modem and Airport router. I will confirm whether this solves the problem. If not, I have an appointment with the Genius Bar on Monday and will probably swap out my device for a new one.

I had the exact same problem too, something is going on. I thought I was the only one.

I have the exact same problem. Gf came home yesterday with the new iphone 7, the WIFI crashed all the time. It's fine after we turned of the WIFI on her new phone.

We have never had problems before, the router is brand TPLink (will look up the model tonight) and I installed DDWRT on it. Will try update the firmware tonight. Getting a new router seems to solve the problem, but Apple could at least give a statement about this.

Just updated the router TP-Link TL-WR740N v4 to latest ddwrt Firmware: DD-WRT v3.0-r30805 std (10/27/16) and everything is working fine now with the new iPhone on the network 🙂

Same issue. Running 10.1.1 on iPhone 7. This has happened on four different WiFi connections and has been occurring since Day 1.

Hello! I have the same problem too. I live in Brazil and get with the new Iphone 7 the sign of wifi internet from home began to fall whenever it starts a download. However, this only happens in my house. I tested in other wifi (public and other houses) and apparently the signal was normal. When contacting Apple here, they told me it would be the first reported case. We did some tests that were not positive. Today I made the adjustment of the iPhone to try to set up as new, but before connecting to the new iphone wifi signal has fallen. In the coming days I will change the router to see if repair the problem. As soon as possible I put an update her

Dropping to WEP may allow connection but is not secure enough!

whats the answer Apple???
