Problems Galaxy S8 Orbi RBR50 and Amazon Echo

Just out of curiosity, when you downgraded to the previous firmware, does your S8 connect on the main network?  I've had to use the hack on my system to turn on the guest network and have my S8+ connect to it.  I've been doing that since the 1.12 version of the firmware, and with the latest 2.0.0.74, I tried connecting to my main network with the S8+ and the same problem.  WiFi stays connected but internet drops.  So, I've switched back to the guest network and it seems to be working fine, albeit very hacky.  

I've had the system for about two weeks and debating if I'm going to keep it.  The connectivity in the house is awesome, but weird bugs like this and also the fact that if I have several people streaming at the same time, it seems like one of the two will just drop everything and be like "That's it...I'm not doing all that"...and then I have to manually unplug and plug everything back in.
