How can I disable the MAC address filtering or add an acceptable MAC address for my HP 8600 printer?

That works! WOW!  I've now wasted so much time dealing with this issue.  T-Mobile should really consider putting that in the quickstart procedure for when you are setting up the home internet.

Your problem is pretty common among T-Mobile Internet users. The following usually fixes the problem.

Add a new WiFi network for the HP. Use the T-Mobile app and tap the Network tab on the bottom, then the "+" button on the lower right. Create a new 2.4 GHz WiFi network with a unique name (SSID), just for your printer. Make sure the WPA type is WPA/WPA2. This is different from your main network which, by default, is WPA2/WPA3.

Now, go to your printer and clear out all of the information you have entered for your printer's setup and then connect your printer to your new wireless connection. See if that doesn't help.

¡Buena suerte!

For as helpful as this post has been, surprised it is not marked as a best answer / solution.  @HeavenM ?

T Life app instructions to create new 2.4 GHz network:

Connect (at the bottom) > Things (at the top) > tap your Gateway > tap Manage > under My Networks, you will see each one you already have. 

To create a new network, tap Network (at the top.)  Under My Networks, tap + Add Network to open the page to set up your new network.  Give it name (SSID) and a password; select the frequency band (2.4 GHz); select the WPA version (WPA/WPA2).  (Encryption mode is automatically set when you select a WPA version).  Tap Save at the bottom.

Nevermind, just realized it works without needing to switch! :)

THANK YOU!  After hours of unsuccessful attempts to connect my HP8600 printer to my new T-mobile router, I used your suggested process and IT WORKED!  Very helpful!!!!

THIS worked!!!!!  Thank you so very much for taking the time (and providing excellent instructions on how to get this done).

Have a wonderful week!

I'm a bit confused about the question. What exactly are you trying to do? Are you only going to allow certain devices or people to access this printer? Is the printer currently connected to the T-Mobile gateway?

Trying to get HP 8600 printer to attach wirelessly to my T-Mobile Home Internet. All else has failed so trying MAC address but cannot get lt passed the filter????  Any ideas are welcome 🤗 

So, I got successful test results from my HP Photosmart 5520 following the directions above, however I’m still unable to print from my Chromebook.
