I am living in South Korea. I purchased a US-made Roku box and connected to my TV via the HDMI port and AC adapter. When I tried to access my Wi-Fi, it could not be detected by the Roku. The Roku uses 802.11 b/g/n dual-band receiver. (I'm thinking that my local Wi-Fi might use a different frequency.) I also had heard that even if could connect to my local Wi-Fi, most of the Roku channels cannot be accessed overseas (except for just a handful of countries now). Does anyone out there have any experience trying to use Roku, Amazon Fire Stick, or Google Chromecast overseas?
