Is your network 5 GHz, 2.4 GHz, or both?
Many ISPs have changed their 2.4 GHz settings from b/g/n to g/n, and that will prevent a Roku device from connecting properly on the 2.4 GHz band. If your network offers 5 GHz, it should connect; that is, I've not heard of ISPs screwing around with 5 GHz settings.
