Roku TV no longer discovered by Alexa

About a year ago I purchased a 42” Philips Roku tv from Sams Club.  I set it up and paired it with Alexa and it worked but was a novelty as I was on a Direct TV dish.  I am now turning Direct TV off in favor of a streaming service but discovered that the TV has lost the ability to pair with Alexa.

About 3 months ago ATT came out and upgraded the router.  Everything was the same and all appeared to work as it did but I did not check to see if the TV was still paired with Alexa.

To date I have removed the TV from the Roku account.  Removed the skill from the Alexa app.  Reset the TV to out of box.  Set the TV back up.  Checked that the TV was back in the Roku account.  Installed the Roku skill in the Alexa app. Then scanned for new devices but found none.

I also went in and forced the router to have a different SSID for the 2.4G and the 5G bands.  The TV is using the 2.4G band same as the Echo show. 

What am I missing?
