We currently have the XFINITY - ARRIS Touchstone DOCSIS 3.0 Cable Modem and Wireless Router with Telephony Adapter linked via an Ethernet cable to an Apple AirPort Extreme 2 and then to two additional AirPorts for coverage in the house... it's a fairly large house with 3 floors. The Xfinity modem is an older one that supports 2.4 ghz but not 5 ghz wi-fi. My Apple equipment supports both 2.4 and 5 ghz. When I do speed tests their is a marked difference in the 2.4 ghz upload and download speeds vs. when I switch to the 5 ghz network in the house. The 5 ghz being much faster. If the Xfinity modem doesn't actually support 5 ghz... am I really getting 5 ghz from the Apple routers... even though I have two separate networks (one 2.4 ghz and one 5 ghz) in the AirPort Utility on my MacBook Pro? I am not a real tech person so don't have any in-depth understanding of this.
The reason I ask is because Comcast wants me to turn in my current modem in exchange for their new one that supports both 2.4 and 5 ghz wi-fi networks. Does it really make any difference if I am pushing wi-fi through an ethernet cable on the modem to my AirPort Extreme 2?
Thanks in advance for any clarity you can bring to my less than stellar knowledge in this area....
