Cannot find Tablo on TCL

Hello,
We have a pair of TCL Roku TV’s.

  • 49S405 - 49"
  • 32S305 - 32"

Both of them pickup the connection to Tablo through our router via WIFI. The 49" unit never loses its connection with the router. Almost daily the 32" unit loses it’s connection and resetting the tablo resolves it.
Tonight I deleted the Tablo TV app from my Roku channel and also reserved IP addresses for each TV.
