(Fixed the problem by buying two new Roku stick 4k for each tv with both having 2.4 & 5g available internet connections......lets see if this works for a while, but for now, all is good)
Good to hear you got it resolved. 👍
----
For the Roku Express 3931 and other 2.4ghz-only Roku device, try using Wireless Mode b/g/n in your 2.4ghz band Wireless Settings of this router and see if that addresses your previous issue with disconnections and needing to restart.
Keep in mind that the Arris G36 is DFS compatible. (able to use DFS channels 52-140 on the 5ghz band). Roku devices cannot currently see or use DFS channels so if you begin to see disconnections on your 5ghz band with these new Streaming Sticks, try disabling DFS capability in your router if you use Auto Channel Selection, or manually assign the 5ghz band to use a non-DFS channel 36-48, or 149-161.
Thanks for the information Gunnar!
