Thanks for responding.
My problem is that my Roku does identify and connect to the local wireless network but can not get to the internet from there. When you connect to the local wireless network with a computer you get to a welcome page and then you have to click on a "connect" icon to proceed to the internet. Since I am not able to see the welcome page with the Roku I can not click the "connect" icon to reach the internet.
I was told by someone that I may be able to use a router to connect. They told me that if I connected to the local network via a router with my computer and then connect to the internet that the Roku should be able to reach the internet if it is also connecting through the router. Their logic was that the local network will recognize the ip address from the router so any device going through the router would also be connected to the internet.
It sounded logical but I wanted someone else to confirm it before I bought a router. I went to Best Buy, CompUSA, and Hhgregg, and nobody could answer my question. I am a little disappointed that electronics stores don't have employees that are trained enough to answer a question I don't feel is that complicated.
Thanks again for your response and any help you can offer.
It sounds very much like the networks you find in hotels, where you are forced through their home page to agree to terms. It might be that you could set a router so that you have the PC online and the roku routes thru the access point to the net (where the ISP will only see the one IP of your router, not one for the roku). That is all probably by design so that streaming devices can't hog bandwidth. If you buy a router, keep the receipt and all the packaging. Sorry I didn't have a magic bullet to solve this.
