Does AT&T offer any DSL modems that feature QOS?

Thank you.  Any particular brand/model that you would recommend?

I like the ASUS line of routers.  They pretty much run the same firmware, so for this purpose they should be equivalent.  Other brands will also have routers with this feature.

Thank you, Jeffer.  What do you think about this one?  I cannot tell if it has QoS or not though.  TRENDnet TEW-816DRM AC750

The TEW-816DRM is a Modem/Router combination that works with VDSL2/ADSL2+, i.e. U-verse-like connections.  I say U-verse-like because AT&T will not allow you to use any gear but that they they provided on a U-verse connection.  I do not know, given that you said 6.0 MBps whether you are DSL or VDSL2/ADSL2+.  If DSL, then you could find a similar device to the one above that is a Modem/Router that supports old-style ADSL connections.  Regardless, you can find a wireless router—with no modem functionality—to put between the modem and the rest of your network.

I found out from AT&T and TRENDnet that the TEW-816DRM AC750 will work with my DSL service and does have QoS.  Thanks for all your help today.
