Thanks Dupondt. I think a sticking point for an hour or two was that my Netgear router seemed to offer a wep option for awhile, and that tempted me into thinking maybe I could make the whole setup work, with some level of security, but then later when I went back I couldn't find it. At some point I upgraded firmware on the router, maybe that affected things.
In any event, the possible $20 solution you mention is unexpected and interesting. I'm slightly less pushing on this today because I did manage to rig a solution which was to pull an old Roku video streamer out of mothballs and an old HP computer screen from 2007 that I had never used, and I used that to tune the Roku to a station on Soundcast, and everything seems to be functioning the way I want for now. I put the soundbridge back with my collection of other unused audio components.
A reflection -
I live in the hills and conventional radio reception here is poor without the hassle of setting up a good antenna. Around 2006 when I bought the Soundbridge (and soon thereafter one or two for friends and family), it was an absolute keeper- one of the top computer or audio components I had ever bought because it allowed me to listen to radio again for the first time in many years outside of my car. It was an important component for me for a few years.
I did evolve eventually to using my TV as an occasional stereo, with my roku bringing in stations, but my tv is not in the right room for me to listen (when I want to listen).
Recently I have been on a kick to set up a separate two-channel audio-only system in a better area for me. I had a record player repaired (sometimes the schedule we are on is based in part on finding the right person for these things) and bought some proper used affordable furniture to help the thing stand on its own (it had been kludged in near a TV in an unwieldy way). So, I listened to some vinyl, listened to some CDS and eventually got around to the question, as I should have realized I would .... I'd like to let someone else do the driving, but I can't do that without an internet radio.... so, that led me to this week's Christmas internet radio project.
Perhaps one thing worth adding is that I pulled not just one but two old Roku components out of storage and both of them worked fine. Ok "old" in this case is a relative thing... they were not decades old..... one component is about 8 years old and other probably about 5-6 years. Neither was prohibitively expensive when I bought it. So, if there was an ethic at the early corporate meetings of Roku to make sure to dot the i's and cross the t's in terms of not cutting corners on long-lasting hardware quality, that does seem to have been born out in a quick anecdotal way in my experiences yesterday.
