@redklay03 issues with a specific channel is usually pointing to a problem with that service. It might be the provider is having service issues, or there's an issue with the app/channel itself. in both cases, the best place to look for support if the service provider. If you are subscribing to this NBC channel directly with NBC, then they are whom you need to contact. If you are getting access though a different channel, say perhaps the Xfinity channel, then Comcast is whom you need to contact. Roku only provides the platform for channel providers. They themselves only offer The Roku Channel and Roku Media Player. For those two channels, Roku is who you would contact with issues.
If you are having problems with multiple channels, then it's certainly possible the Roku device is having an issue. But it's also possible there's a problem with either your home network or your Internet access. But with only one channel, it's unlikely to be the Roku, your network, or your Internet access.
One final caveat: I did encounter problems with Netflix once several years ago. After intense investigation by my ISP (with prodding from my state's AG office), they discovered that something outside their firewall, meaning somewhere on the Internet itself, was interfering with my Netflix connection. If it's something like that, it's out of the hands of your ISP or the content provider. My problem went away on its own after about 4 months. Whoever was messing with it must have finally tired of hijacking Netflix streams.
