Sharp Roku TV and connection to TabloTV Live TV Menu

I purchased a Sharp Roku TV and have the TabloTV 4-Tuner Device. I have found the Sharp TV with Roku built into it to be slow displaying the Live TV Menu from the Tablo Device. It takes about 30 seconds to upload from a grey out version. How can I get the Sharp TV with Roku built into it to respond with Tablo Live TV Menu in a quickly? I am setup to a NetGear Modem Router and connected with 5.2 GHz WiFi speed.

I had used separate Roku Streaming Stick and Roku Ultra and the Menu for the TabloTV displays almost immediately. I purchased the Sharp TV with Roku Built into it to have just one remote. Any suggestions?
