I don't understand broadband/wifi
I have a bunch of vimeo stuff to watch. Shiny iMac was giving me bursts of 3 seconds then pausing for more like 10 seconds. I tried cheap Windows laptop and it streamed fine, though the picture and sound were a bit crappy. Both machines are in the same room as the router, running wifi, and both are less than 4 months old. Speedtest shows 0.9 Mbps on iMac and 6 Mbps on cheap Windows laptop. Any suggestions?
