I was under the impression that 3 Telus boosters are the maximum. It sounds like you're trying to set up 4 in total. Could this be why the last one only shows a red light?
Is there more to it than just plugging an ethernet cord into the booster and then into my laptop? I tried this after I turned off the wifi on my laptop but I don't get an internet connection. My booster says that it has a good connection.
