iPhone 11 Pro Max not connecting to wifi; suddenly!

[todd1010]

Not sure what is going on here but my wifi SSID’s are visible, I can connect on other devices and my phone has been connecting to it perfectly fine for the last year and a half.

All of the sudden today it asks for the wifi password and after I enter it it says unable to connect. Out of nowhere this just started.

All other 32-33 devices in the house are connecting fine.

My router is a Netgear RAX120

Also, on my phone I’ve reset network settings to see if it would fix itself and nothing changed along with restarting my phone.

   Recent iOS update?  Is Access Control enabled on the router?

   Not all on the same radio band?

   Not RAX120v2?  Look for "Model" on the product label.  Firmware
version?  Connected to what?

iPhone has been on 14.4 the latest update since it came out without issues.

The Netgear router shows no update either.

I’m interested in this Access Control! I need to find what this is and how to figure out if this is keeping it from connecting.

   Doesn't really answer the question, does it?

   If you don't know what it is, then I'd guess that you're not using
it, but visit http://netgear.com/support , put in your model number, and
look for Documentation.  Get the User Manual (at least).  Read.

   While you're in that neighborhood, you might verify available
firmware.

WOW, several of my devices are all of the sudden just like my iphone. My wifes school laptop and my iPhone aren't able to connect even though they have been for years. Now even after putting in the correct password (verified correct) it will not connect. 

UGH!

   "verified correct" _how_, exactly?  Which radio band are these
devices using?  Have you looked at the stuff in the User Manual under
"Specify basic WiFi settings"?  Does the router think that its
wireless-network credentials are what you think that its
wireless-network credentials are?  For both radio bands?

Alright, I dug into Access Control I had it turned off but did turn it on and deleted a bunch of old devices I no longer have. There were two devices one wired connection type and one wireless. 

Two devices showed back up, one was a wired device I edited it to allow access since its wired. 

The other device I deleted it again and manually added my phone via its MAC address and name and clicked allow, applied the settings tried to connect again with the correct SSID and password and my phone still won't connect.

1) I verfied in my wireless password settings for each band that the password was what I was typing. 

Which radio band are these devices using? 

2) For this, I've just been trying to connect to the 2.4Ghz band

Have you looked at the stuff in the User Manual under
"Specify basic WiFi settings"? 

3) I have not but will right now!

Does the router think that its
wireless-network credentials are what you think that its
wireless-network credentials are?  For both radio bands?

4) I have both wireless band named the same except for the 5ghz band has "-5G" after the name. If this is what you mean.
