Does MAC filtering even work anymore?

@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?

Hi, @dyfd. Thank you for getting back to us. Have you had a chance to try the steps that were provided by our awesome Expert @jayweaver0312 in this forum? If so, did it help with the MAC address filtering issue you were having?
