@Maxboy2023, what's the model number of your Roku device written on it or displayed under Settings->System->About?
Edit: I see from your other post (there's no need to post in two different threads) that your model number is 3920. It will only connect to 2.4GHz networks with the wireless mode set to b/g/n.
