I do not have a long enough RJ-45 to reach the router or modem, but will try relocating box to a PC near the router and cable modem later this evening.
The internet connection is not dial-up, it is a broadband cable service.
This is a "brand new just out of box Roku" and once you plug it in it goes through the selection of wired/wireless internet selection, security key, and maybe one or two other screens that are really just user prompts. There is not an option screen to choose if you wish to perform an update or not.
***** To the people at Roku, it is my opinion that soft/firmware updates post-purchase should be optional, and that a brand new product should be shipped with the latest soft/firmware pre-installed. As a consumer, when I receive a brand new product the first thing I do is make sure it is not broken and appears to work. For electronics such as a router or PC, I will verify functionality first, and then process updates if I am interested. In this case, the device is definitely not as plug-and-play as the cartoon like installation sheet makes it appear. As it stands I do not know if my product works or not, and as I understand the terms of sale and/or warranty offered by Roku my clock is ticking. *****
