@Netwerktek Let me know how your situation plays out.  I was able to get one of the two consoles to play fortnite on his xbox.  I had to do dmz and port forwarding to that console, but that doesn't solve the entire problem.  It seems like when they pushed out this 1.3.2 firmware, it appears to have overreached on security and almost nothing goes out and is super unstable as you have mentioned.  If I'm home, I can't access my cameras at all unless I disconnect from the wifi.  Really close to just cancelling my subscription with tp-link and looking into another option that is more stable and provides less issues.  I originally went with this router because they have a semi-easy to use app for my wife to turn off the wifi to the kids' devices as an option for discipline, but what's the point when they can't access the stuff they want to play.  Today I'm going to be taking my modem out of bridge mode and using that entirely until a permanent solution is in place.  

  @CorruptedxDatax I was unable to resolve the issue with TP-Link for the Deco units I have. They wanted to do a remote session on my computer, install some debugging software, etc. that I wasn't comfortable with. I decided to return the units (thanks Costco) and I am currently running ASUS ZenWiFi XT8 mesh that I picked up from Amazon. Pretty solid thus far and I was able to create separate SSIDs for the 2.4Ghz and 5Ghz bands. Good luck.
