Re: How do I access my wireless cable service from Roku??
The latest version of the Roku Premiere (it's not the model they call the Stick) uses the 2.4 GHz WiFi band only. It does not support the 5 GHz band. But I'm not aware of any WiFi access point/router that doesn't support 2.4 GHz. So you should have no problem connecting it to your existing WiFi system. Simply go into the network settings and have it search for your access point.
Dan Roku Stick (3600), Ultra (4640), Ultra (4670), Premiere (3920), Insignia 720p Roku TV, Sharp 4K Roku TV, Nvidia Shield, Windows 10 Pro x64 running Serviio and Plex on a wired Gigabit network.
