New Roku Premier 4k - Won't see 5g wireless

Jump to solution

I've been reading about the issues with 5g wireless channels and have tried 36, 40, 44, 48 153, 157, and 161.  My older Roku streaming stick sees each of these channels and I can see in the about connection screen that the channel is updating.  The brand new 4k Premier, however, continues to fail to see the 5g network.   Has anyone been able to connect this to a 5g wireless network?  Is this even 5g capable?  Do I need to change the frequency or even the channel width?

Thanks in advance, I'm frustrated as there's no longer someone to talk to.

The new Premiere 3920 and Premiere+ 3921 models are single band 802.11b/g/n 2.4 GHz only; there is no 5 GHz capability.

Also, just a point of terminology clarification. 5G refers to a wireless cellular protocol. With Wi-Fi, you are referring to radios that support the 5 GHz band. Not the same thing. There are different protocols with Wi-Fi as well, usually referred to by their official IEEE designation of 802.11 A/B/G/N/AC. Not all of those protocols support both 2.4 GHz and 5 GHz (the two radio bands authorized for Wi-Fi use). This chart shows the wireless capabilities of all past and current Roku devices. If your device doesn't say Dual Band, it only supports 2.4 GHz.

I should have done my research before buying it.  Why a streaming device would be made without access to 5GHz WiFi, astounds me.  5 GHz has greater speed and bandwidth than 2.4 GHz.

Not every Roku device supports 5 GHz WiFi. I don't know which TV you have, but that's most likely the issue.
