I have 2 ROKU Premiere devices. The serial numbers are
YH009E133102 and YH00FV573728.
Spectrum is my internet provider. I have a Spectrum Router/Modem. In setting up both my ROKU devices I only have the standard internet connection visible. I do not get the 5G connection I see on my I-Pads, Laptop, and Cell Phones. How do I enable the 5G connection?
First, it's 5 GHz, not 5G.
Very few Roku devices support 5 GHz. Most only have a single band radio on 2.4 GHz. I can't tell what model Roku you have from the serial numbers. But unless they are the very first Premiere models (model 4620/4630) from four years ago they do not have dual band radios. So you can't connect to a 5 GHz WiFi access point.
