Bought the AX55 to replace an older/slower Archer router.  Everything seems great with the exception of this issue with Samsung TV Plus.  Will be returning the router to Amazon if I don't get this resolved, so hoping someone from TPLink (or the community) has a fix.

To summarize, my Samsung is connected to the Archer, which sits behind my provider modem (ATT gigabit).  Router handles all the LAN assignments and traffic, modem is the gateway.  Setup worked fine before, largely with the same settings, and mostly works fine now.  

The ONLY issue is that the router refuses to allow the Samsung TV to load Samsung TV Plus content.  When I select an STVP channel on the TV it will show me the guide, show me the channels, show me whats on, etc, but it will NOT resolve the actual channel/video.  It just shows a black screen.

I know this is an Archer problem because, when tethered to my phone or another hotspot, the TV still works fine, and it worked fine before I switched it over to the AX55.  I have tried EVERY solution provided on every forum to try to resolve this, to no end.  I have:

- Switched the TV between wired and wireless

- Manually managed/changed the DNS servers and IP assignments (thinking maybe a manual IP for the TV on a reserved block would work... no joy).

- Reset/reinstalled the STVP app, and even nuked the entire Smart Hub on the TV.  Again, no joy.

- Rebooted the AX55 and made sure it's updated

- Modified various settings on the AX55

I will say that this problem seemed to happen right around the time I started using the Tether app and linked my TPLink ID with my unit.  It seems insane that that could have anything to do with this, but... I've seen stranger stuff when it comes to how some of these services are configured.

Anyway, hopefully someone knows the final solution to this, because I'm about done giving TPLink anymore of my hours/time for free QA.

Thanks,
Dante
