I gotta say - Mike - if its people all doing personal usage - you shouldn't have to support that since its NOT Work related. Here at my job - security is a Huge issue - since the co. is centered around financial data. As such, we have NO Free WiFi access. Oh well...
I WILL keep an eye on this thread - since if it sheds any light on your issue - maybe it will help shed light on my own problem at my place.

Exactly. I've checked a few of the phones that won't route and they have a valid IP address, they have a valid gateway value, but no DNS.
The problem I am dealing with is a couple hundred employees who have come to expect free high-speed WIFI at work for their cell phones and tablets (personal stuff, not work related.) And I'm astounded at how rapidly people change phones!!! I looked at one guy's Android phone a couple weeks ago, and yesterday he shows up with an iPhone. A girl I helped connect her Android last Friday sent me an email today "warning" me that she is getting a new iPhone by the end of the week and she's heard that people are having trouble getting WIFI on their iPhones.
What I've done on the Androids is remove the WIFI connection from the previous connection (the WAP hasn't changed, but I did change the password at the beginning of January) and then reconnect. So far I've only had one Android that didn't work on.
There's a similar 'fix' touted for the iPhone when you google the problem, but so far it hasn't worked once on nearly a dozen phones.
The problem is almost identical each time (the wording changes depending on whether it's Android, iPhone, and what flavor of Android.) It prompts for password, accepts password, indicates it is getting connection details (IP, etc.) and then it finally finishes without further indication there's a problem. But when you try to access the Internet, it routes through the phones data connection (LTE4 or 3 or whatever their carrier provides) and not WIFI.
I've looked at the DHCP server and it shows the devices by MAC address, with a valid associated IP and lease. Everything on the DHCP servers looks right.
I'm going to replace the routers and try having the router assign the DHCP values and see how that flies. Nothing else is working.
Thanks!

Yikes. That sounds like a "fun" problem. Sorry, bro.
You say it seems to be a DNS problem. Why do you think that?
There are info screens on iPhones and Androids that will show you IP address & DNS settings, though they are often difficult to find. My Android will happily set DNS1 & 2 to 8.8.8.8 and 8.8.4.4 if you don't specify. Do you block devices that want to use their own DNS settings?

Anyone else having problems with WIFI WAPs starting to refuse connections to iPhones?
I manage several building networks that have WAP devices, and I've started getting complaints in the last couple of months about "my cellphone won't connect." It seems that the connection happens, but the data won't route. From what I can tell it's a DNS issue. (The WAP is on an isolated network with a DHCP server that provides an IP, gateway, and DNS settings when connected.)
I've Googled this and read for hours, and I have found some "fixs" that didn't work when tried. Mostly it's iPhone 6's but a couple of Android phones, too. No idea what flavor of Android.
It is happening with both Cisco WAPs (Aironets) and Netgear. And once a device connects, it's happy happy to come and go, reconnecting as needed.
Any WIFI gurus in the crowd?
Thanks!
