Asus AX11000 Compatibility

Hello @Bld(Edited per community guidelines)r2005 , we will be happy to offer some assistance with your router inquiry.

We cannot exactly confirm if the AX11000 will be compatible with an AT&T gateway. If it is, you would need to set it up the behind the AT&T gateway. You can do so by following the steps on how to do so. It has pretty thorough directions on what needs to be done and how.

If that does not work, we recommend contacting the Hometech team for further assistance.

Please let us know if you have any other questions.

I would recommend against the Hometech recommendation.  However, I agree with the rest.  AT&T doesn't support any particular model of router behind its Gateways; most will work fine.  The ASUS routers are widely used by many, I use one myself, though not that model.
