Roku Express and No 5G

I've looked through the various forums, but I'm coming up empty so I thought I'd throw this out here:
New Roku Express (3900x) - will only "see" my 2.4Ghz network which is too slow for proper playback (the Roku even says so itself).
I logged into my router and changed the SSID to both a low station (36) and a high one (157) - neither time could it find my 5 ghz network.

A couple of questions: 

1. Does the Roku Express even support 5Ghz (some forum posts said no)?

2. If it DOES support 5ghz, is there something else I should try?
Thanks,

Don't think it supports 5Ghz.
Yeah, I got some Rokus.

Re: Roku Express and No 5G

Yeah, I kind of ruled out any other reasons why I couldn't get it to work other than an act of God to make it 5ghz compatible

Re: Roku Express and No 5G

I have 5 Roku Expresses scattered throughout my 3400 sq ft home with double-paned storm windows and doors, including one in the farthest corner of the garage and another on a wall mount outside by the pool. None of them have any issue streaming anything through my Arris wifi cable modem that sits on top of the entertainment center in the family room at the back of the house. 2.4ghz band works fine for me.

Re: Roku Express and No 5G

I found the specs page for Roku Express and it says it receives an 802.11bgn single band wifi signal. When I Googled that to see what it means, I got this result:

"802.11bgn Wi-Fi routers are single band. This means they support only the 2.4 GHz band."

So that tells me that our Roku Express antennas will not receive the 5.0 GHz signal from our modem/router that is putting out both a 2.4 and 5.0 signal. Here's hoping the 2.4 works well enough.

That is correct. Single band devices only work on 2.4 GHz. However, virtually all recent wireless devices support at least 802.11N, which is in theory capable of speeds in excess of 100 Mbps. No Internet streaming service streams much higher that 16-20 Mbps. Unless you are streaming from a personal device on your network, and those streams are full 4K UHD Blu Ray rips, you'll be just fine. The only noticeable improvements you get with 5 GHz are faster speed and less interference. And as I said, in most cases the speed is immaterial.

Re: Roku Express and No 5G

I have 3 Roku express units ranging from 1 to 7 years old. All were connected to 5G fine until earlier today when they all stopped working. My router is still putting out all the wifi signals and other devices detect and can connect, but not any of the Roku. I am able to connect to 2.4 ghz on some of them, but it's a poor signal strength.

The Roku Express was first released in Oct 2016, so you don't have an Express older than just under 4 years. Also, no Express model has ever supported 5 GHz. They have never had a dual band WiFi radio, so 5 GHz support was impossible with those players. Perhaps you don't have Express players, but instead have the Premiere/Premiere+. The original versions of that player (4620/4630) did have dual band radios, but all newer releases switched back to single band (2.4 GHz only). So please clarify which model numbers are shown on your Roku players. 

As far as 5 GHz goes, there are only a subset of channels that Roku devices will work on. The unavailable channels are labeled as DFS, and have restrictions on their use almost worldwide. That's why Roku doesn't even support those channels. When wireless access points are set to select a channel automatically (as almost all do with factory settings), it's possible for them to change channels on their own, and they might have selected a DFS channel. The solution for this is to assign the channel yourself manually. You need to assign a channel number 32-48. or 149-165. If you're located somewhere other than North America, you might need to confirm what 5 GHz channels are permitted for use there. They aren't all available everywhere, but the DFS channel numbers are consistent world wide.
