RBR/RBS50 2.1.4.10 dropping internet

Hmm, I see my SB6190 listed as a bad modem.   It would be odd in my mind if issues with the modem caused some clients to loose internet and not others, but as this modem looks problematic and I have an older modem that should run as fast as my ISP specs I will swap that out first and give it a try.  In the interest of speed I will also turn off daisy-chain.  This may kill my performance upstairs but it is worth a test.  MU-MIMO, Fast Roaming and BEAMFORMING are all off, I hadn't looked at turning them on and they seem off by default.  Thanks for the pointers, I'll start here and see if I can improve things.  I have a gut feeling about daisy-chain, though that not working would bite.  I can try to work out a better setup, but I was counting on not pulling cable up from the basment, and placing the satilites where I need wired connections.  Hence the dual satilite setup (with all the $$$)!
