iPhone 12 with IOS 14.2.1 WiFi connectivity issues

I cannot answer that, however I can say that my iPhone 12 Pro connects to my router just fine. Try updating the firmware on your router. Unless your router is so old that it is not setting up correctly at all, it should connect. See this support document for information on setting up your router. https://support.apple.com/en-us/HT202068

I had to connect manually with an IP address to get it back on. Works fine. Hopefully it will get fixed for real, but manual connection does work.

I have the same problem with HughesNet and another service I tried to be sure it was my phone and not the other way around. iPhone 12 Pro Max connects to WiFi but no internet. My iPad and old iPhone 11 Pro Max connect fine.

I'm also having random Wi-Fi disconnects while other non apple devices are connected to the internet. I have tested this with every troubleshooting and connection configuration guide apple has provided. No fix yet. The only temporary fix is basically turning off/on the Wi-Fi. Currently running IOS 14.6

My new iPhone 12 will not connect to my office wifi (Belkin) but my old iPhone 6 still connects no problem. Both phones connect to home network (Orbi). Is there an issue with older (Belkin) router/wifi signals compared to newer router like my Orbi? Ive tried updating firmware on Belkin router but no help. Restarted phones, reset network settings - all no help.

This is a iPhone 12 problem. My older iPhone 6 works fine with my older router and internet but my new iPhone 12 will connect to the router network but will not accept the internet connection. What is different about iPhone 12 that it won't talk to an internet connection thru an older router?

I’m in the same boat. Was dropping Wi-Fi every 20-30 seconds, now dropping every 2 seconds. Useless. I have 50 items connected to this network flawlessly. Only the 12 Pro Max doesn’t work. Hope the next update fixes it. Really don’t feel like wasting my time fixing something that worked perfectly day before yesterday.

Same problem with connectivity issues for over 5 months now. I was wondering why my cell usage was going over so much. Apple changed out my SIM card and also sent me to AT&T. The problem still exists. I’ve even tried installing a new modem and router in my home (which all of my other devices work fine on). Turning the iPhone 12 Pro on and off fixes the problem for about 10 minutes then loses connection after. Even as I’m on the phone with Apple’s tech support the connection is lost and they can’t figure it out. To top it off, the tech that I was speaking with says “it’s the first time they’ve heard of this problem”. So, I directed him to this thread so he could now be aware of this problem but he didn’t want to read it 🤔. I just wanted him to be aware of the problem so we can all get this fixed🤷🏻‍♂️, right? Frustrated!

I have read so many issues with Apple 12 iphone about Wifi connectivity. It is absolutely an Apple issue. They need to fix this and not give us all this mumbo jumbo about new routers, etc. Had technicians out from 9am unto 2320pm and now its worse. Read that you need to change back to 4G. Then what the heck did we purchase a 5G phone for? I'm really ready to return this.

I have a WIFI connectivity issue also every time I walk into the reach of public Xfinity service in stores, occasionally Spectrum at home. In order to access apps, web, etc, I have to disconnect from WIFI and go cellular. Then everything is accessible. Not a show stopper but really aggravating at times, makes work.

Same issue. Upgraded from XS Max to 12 Max, and spent half the day trying to get WiFi to connect. It shows a clean connection on settings, but zero WiFi bars on screen.

I have two separate WiFi systems, from two different carriers, and two different mesh systems. Same issue on both. The second router is less than 6 months old.

why did I upgrade??

Excellent suggestion! I was on the phone with an agent from Xfinity for over an hour....with no luck. Saw your post, reset my network settings...now my 5ghz not only works again, but is lightning fast! Thank you!!!!!

Yeah this won’t work. Here’s what happens:

sitting on the couch you pick up your phone and try to pull up the webpage. You look up and see you’re connected to Wi-Fi but the status bar pulling up the website pauses about 25% along the way and won’t move. So then what those of us having this problem do, we turn off Wi-Fi and then let cellular data search the web. If we turn Wi-Fi back on then we can search the Internet using Wi-Fi. This is a problem on an iPad Pro MacBook Pro iMac another iPhone 12 Pro, I only have the problem on an iPhone 12 promax. It’s very frustrating and it’s not my home router system.
