T-Mobile won't connect to Roku TV
Hi, has anyone discovered how to connect to a Roku TV?
Also, you might have to downgrade to WPA2 if you were using WPA3.
Is it that your Roku does not see the SSID? This happens if your Internet Gateway is on DFS for 5gHz. Found out the hard way after some head scratching then turning on Wifi Analyzer on the phone. LOL

Stay with 5GHz Wi-fi channels 36, 40, 44, and 48
According to T-Mobile:
Does T-Mobile support Roku TV?
The service will work through dedicated apps on Apple iOS and Android phones and tablets, as well as TV streamers and smart TVs including Apple TV, Amazon Fire TV and Android TV/Google TV. There is, however, no support for Roku, game consoles, Chromecast or AirPlay at launch. 2020
Your success may have to do with the Roku TV device you are using so it is maybe important to know the specific model/revision to be sure.
There are 10 generations of Roku so it might be helpful to know.

Go to the WIKI and look at the 802.11 wireless and identify the wireless band(s) it uses. If it is one of the models that supports Ethernet then using an Ethernet cable to connect it would make it simple. The 4800 from 2020 and others going forward also support a/b/g/n/ac dual-band MIMO. Some versions also supported Ethernet adapters. So, knowing the model and revision of the Roku and the wireless capabilities will help work out getting it connected.
I doubt that you would find an Arcadyan or Sagemcon gateway on DFS channels. Their configuration is so limited it is probably not an option. The Nokia is another story as it does support the configuration of those 5GHz channels. I could be mistaken but I don't believe the Arcadyan or Sagemcon have as extensive configuration for wifi channels.
Since there are so many different Roku models I would just guess it is either an older one without 802.11ac or ax or the authentication type it requires might not be available. If the gateway is defaulting to WPA2/WPA3 and the Roku model requires WPA then the authentication type on the gateway needs to be configured to allow the needed authentication type. Not having WPA authentication type available is one of the most common issues when connecting earlier generation wireless adapters.
Also, you might have to downgrade to WPA2 if you were using WPA3.
My replacement Arcadyan Internet Gateway defaulted to DFS (Sagecomm did that initially but I guess it detected radar and moved itself away) so I had to connect my Roku to my Mesh Router. Needless to say, I just discovered that I could not use channel 60 nor WPA3. LOL
That's interesting. It seems surprising that one of the two newer gateways would actually have DFS running. T-Mobile turns on the thumb screws on so many options that is really a surprise.
In looking over the WIKI info on the Roku models the subject of authentication types is never mentioned.
The Arcadyan router claims to be WiFi6 compliant..and I thought DFS channels are part of the deal with that.

they couldnt run WPA3-Personal-Transistion?
I would have to look at the standard to know but you could be right DFS might be allowed with the 802.11ax operation. I don't know that the DFS channels would be enabled by default.
