I have a 2008 mac mini with a time machine, this has a ethernet cable directly connected from an older virgin motorola modem. The mini then uses the network to connect to the wireless network. 1.Is this the best set up method to get good internet speed and streaming. 2. Virgin has sent a new (virgin super hub, NETGEAR) combined modem and wifi router, if i use this will it clash with the TM. Is it best to use the new router as the modem and connect ethernet direct to TM or just create a new network using the wifi router. I am after the best signal and stability for streaming.
