Does MAC filtering even work anymore?

I have been using MAC address filtering to limit which devices can connect to the 5GHz WiFi, forcing everything else to connect to the 2.4GHz WiFi  The 2.4GHz and 5GHz connections have the same SSID and password.

I have a model TG1682G router running 10.1.27B.SIP.PC20.CT.   I've recently noticed that iOS devices that have Private Address enabled are able to connect to the 5GHz WiFi even though they are not on the Access List.

Can someone explain that to me?

That is a great question,@mph100 ! If you don't mind, are you able to reboot the modem to see if that fixes anything for you? Also, have you gone into the admin page to see if anything is altered there? You can get there by going here, 10.0.0.1. If none of that works, you can also send me a DM as well

@XfinityJosephB I don't mean to get off on a rant here but.....

Rebooting the modem doesn't fix anything.  What I showed previously (which you deleted - not sure why you consider MAC IDs and IP addresses "Personal Information" as they are hardly private from a mediocre hacker and one of the reasons for Apple creating the Private Address function, but I digress) was from the router admin pages which demonstrated that the MAC ID of a connected device was not on the CONTROL LIST that was set to "Allow".

I'm not really inclined to contact technical support.  I find it incredibly frustrating when they ask me to do obvious troubleshooting like, rebooting the modem and are more interested in getting through their script then listening to my problem.   I've been down that path several times before on other less technically involved issues and I just get tired of it.

I understand MAC filtering isn't really a thing anymore but obviously iOS devices can easily skirt the control, at least on this router with this software version. At first I thought it only allowed iOS devices that were connecting with a simulated MAC ID, which is what "Private Address" does.  That in and of itself is odd but technically not an issue.  I soon discovered, however, that any iOS device with the SSID and password (shared by both WiFi signals) would start as connected to the 2.4GHz signal but at some point transition to 5GHz signal, if Private Address is enabled on the device.

As a work around, I've separated my 5GHz and 2.4GHz SSIDs (which the system seemed hell-bent on my not doing) and have forgone any use of MAC filtering.  Which means the issue is basically OBE but, on the bright side, my iOS devices have stopped claiming my WiFi connection isn't private.

Ditto @mph100s problem.  Devices on the "Allow" list are not allowed to connect, and devices on the "Deny" list are not prevented from connecting, with or without combined SSID's for 2.4 and 5g

I want to enable MAC address filtering on my TG4482A gateway (Firmware:  TG4482PC2_4.12p9s1_PROD_sey) but do not see that option when connecting to it via 10.0.0.1 -- anybody out there able to help me find it so I can create an "Allow" list and deny all other MAC addresses that are not specifically allowed?

@mph100 I think you have more info than the support people seem to. Can you help me enable MAC address filtering on my TG4482A gateway?
