iPhone 16 Pro Max iPhone 16 seems to be crashing my router

[anthony13]

Both my wife’s iPhone 16 and my iPhone pro max 16 are crashing our home router. As soon as they connect it crashes repeatedly indefinitely until we turn off WiFi on the phones. I ‘reset network connection’ on the phones but that didn’t help. Any ideas?

The router itself is from the cable company.

What Wi-Fi does your home router support? Then new iPhone 16 models support Wi-Fi 7 which is 802.11be. What iPhone did you upgrade from?

WiFi 7 offers speeds up to 46 Gbps, compared to 9.6 Gbps in WiFi 6 and 6e and 3.5 Gbps in WiFi 5. Tri-band data transmission as WiFi 7 operates on the 2.4 GHz, 5 GHz and 6 GHz frequency bands. Yes it tries to use all 3 GHz bands.

Upgraded from a 15 pro max. The router is a 2.5 band and 5g band, and I’m connecting to the 5g right now. Trying to determine the model and what WiFi it is now

Try 2.4Ghz

I think I may be experiencing this as well with my ASUS RT-N66U. Trying to troubleshoot, but wifi on it has been garbage (slow and inconsistent connections) ever since I connected my new iPhone 16 Pro. Edit: and I've already tried reset the phone's network settings since I transferred all my settings from my 13 Pro.

Cable company routers are less than ideal in my environment.

Tossed it aside as soon as it arrived - never used it.

I use the UniFi / Ubiquiti router & wired access points for my house.

I can easily see connection issues and what traffic is being denied.

So switching to 2.5 seems to have stopped it. When I switch to 5ghz the problem comes right back.

Try changing your 5GHz SSID to something different than your old.
Then change the PW to your 5Ghz SSID.

iPhone should connect as a new WiFi access port.

factory reset your modem, then log in To Your router and change the power usage of the 5ghz, just choose a different band on the 5ghz range, if you live in an apartment complex or have a lot of modems nearby it could interfere with your 5ghz service.

I don't use the 5 GHz band on my router. The weird thing is client name shows up as "iPhone" which is not the name of my phone. It was briefly that name after I reset the phone's wifi settings, but I renamed my phone immediately and have connected and reconnected to the router several times since. Will try rebooting the router again.

Been having WiFi issues as well with 16P. I turned off the 6e setting on the iPhone and that seemed to solve the problems for now. Using UniFi equipment. Seems like there’s some bug as others on Reddit are reporting issues as well.

My wife’s phone appears to be crashing the router where she works too. It must be some sort of oddly coincidental and isolated problem otherwise I feel like there’d be more posts about this.

This issue suddenly pops up for me, Googling brought me to this thread. There were 0 issues the past week but suddenly it started happening today.

If someone know how to fix this, please do share. At the moment my workaround is to connect to the 2.4ghz band.
