XB8 MAC filtering does not work

The MAC filtering for the XB8 does not work. Any item that has access to the password will be connected. For instance, anything in the MAC auto find list will be connected even though it is not on the ALLOW list. Please let me know how to fix this as it makes the XFi app pause redundant as the MAC address can be easily changed to get access.

Thank you for reaching out to us here @user_f52vdk. I would be happy to check on any issue with your modem from here. Could you send me a direct message with the full name and complete address for your service?

   Click the "New message" (pencil and paper) icon

   The "To:" line prompts you to "Type the name of a person". Instead, type "Xfinity Support" there.

   - As you are typing a drop-down list appears. Select "Xfinity Support" from that list.

I have spoken to many “technical people”at Comcast and the best they tell is “turn off and on the router” 

unacceptable!

very poor indeed

XB7 and XB8 mac filtering is terrible!

you put Allow on MAC address for 2.4ghz and they move to 5GHz! Put allows on 5GHz for the same max addresses and it block everything

Comcast, this is a serious loophole where max spoofing is easy.

The support sucks and the product sucks and nobody has an idea how an actually router works!

done with it and I will buy my own..

All, for the XB7 gateway the MAC filter the 2.4GHz when “Allow” it locks out the 2.4GHz and 5 GHz signals so that nothing can connect.

However, when the 2.4GHz is “Allow-all” and 5GHz is allow. It works as expected: 5GHz max filters. 

This is really bad! Please help fix so that the mac filtering works with Allow on 2.4GHz and 5GHz.

Hello user_f52vdk

 

Below is a great link that breaks down the band steering process. It has a stellar group of FAQ's and background. You can also update your WiFi name and password by selecting your network from the WiFi tab in the Xfinity app and then selecting Edit WiFi settings. Here’s the step-by-step process.

Thanks. I am still having issues. The Mac filtering on XB7 does not work.

on 5GHz if I hit “Allow” every item with access will switch to 2.4Ghz and still be connected. 
if I have “Allow” in 2.4 GHz as well as 5GHz everything is blocked!!!!

Does anybody know what is happening. My kid is Mac spoofing to get around the XFi app and only Mac filtering on XB7 will stop this…

This is the official response from Comcast on my Max spoofing issue: buy another router! This is terrible!

Thank you for confirming that! At this time, it is recommended to purchase you own compatible modem and router or gateway to have more control on the network features. For the time being, it is recommended to pause devices in the Xfinity app and change the network name and password as needed.
