Well, after a good deal of time reading, I think I have some answers. Garnering info from this site, and another one, I fin I now know something. After more leg work, I will hopefully find out more. Then, just get opinions on doing the WiU add on with the old, or getting rid of the old and getting the WTIU. I know which way I am leaning, for my situation, but am guessing everyone else will have different decisions regarding advantages/disadvantages of each option. May I will start a topic on that. Thank you for your patience with my question, sorry I did not do more "legwork" before posting my question.
This reply, "My advice is pick up Barry's book: The DCS WiFi Companion 2nd Edition Paperback That should answer any questions about the TIU and WIU." is a good one, and one I use if I thought I might go wifi running. But, I do not see a need until I decide which route to take. If I decide to opt for WIFI running, you can bet I will be purchasing. Thanks, Greg
