SUCCESS! (Well, sort of... read on.) I've got other things going on, so this took a while.... After researching and corresponding with Trendnet, I think I've got it set up with the best performance possible. (I learned how to make a simple parabolic reflector out of aluminum foil; this was fun, but did not improve signal reception by the Roku.) Trendnet did help out, however, I had already experimented with their suggestions; they offered nothing that improved the signal strength. (I reviewed the router at Newegg; it's the most recent review, using my user name of "beat," as in tired, defeated, and giving up.) The best signal strength I can get is 3 bars on the Roku (as it searches and detects networks). 3 bars (strength of detected network; 3 of 4-bar maximum) is enough to set up and activate the Roku. Yesterday I did that, getting on the Chat line so I could activate my Roku account without having to provide my credit card information. The process went quite smoothly, with the support rep asking me to check the progress on my TV as we went along, and then try a free (no subscription) channel. No problem!
I signed up for the free 30-day trial at Netflix. This is where the disappointment comes in. Last night I thought I'd watch the movie, "Green Lantern," since I missed it at the movie theater. Did a search for it (far easier on the computer at their web site) -- but it's available only on DVD!!! Netflix wants you to double-up on your subscription fees by opting (in addition) for the DVD rental option, bringing the total monthly fee from $8 to $16. Crappy deal. So, I watched Captain America. All went well. I had wondered previously how it would look on my standard TV screen -- it had the typical upper and lower black borders to yield the typical wide screen/movie screen format. I did search with the Roku for Green Lantern (awkward and time-consuming compared to using a computer) but it yielded no title. So, I see a bunch of titles and I see "Burn Notice." I ended up watching three episodes of this, including the pilot, after watching Captain America. Good show.
This morning my wife says she wants to watch "The Life of Pi." A few minutes ago on the computer I searched for it at the Netflix website and this also is available only on DVD.
I am getting pissed. Obviously this is an intentional ploy by Netflix to squeeze more money from its subscribers, but I'll have nothing to do with it. We don't watch that many movies, and I'm not going to spend $16 a month for them, or for the ability to watch them, as the $16 would be charged no matter how many movies & DVDs you watch. Is there a good alternative -- one that really has a good movies selection for on demand viewing -- available. Amazon, perhaps? I have no idea. Any suggestions?
My next step in developing my home network will be to research and set up a NAS unit. That will really be a challenge compared to my Roku ordeal.
