I currently have a new Time Capsule (the AC tower version) and have it set to extend wireless networking to a couple of AirPort Express routers (1 of the older wall-plug style, and 1 of the current AppleTV sized style). Both Express units report "Excellent" connectivity and are running on 802.11a/n at between 216 and 275Mb/s. Would I benefit from upgrading 1 or both of those Express units to the new Extreme AC model? Would the Time Capsule to Extreme AC offer higher throughput? The reason for this question is that I just purchased a TiVo setup and am experiencing some intermittent connectivity issues. Currently I have 2 TiVos connected to 1 of the Express routers via a switch. So the TiVos are not running wirelessly per se. I know I can add a MoCA network to run the TiVos, but would rather accomplish via the AirPorts as I have other uses for the AirPorts anyhow. Thank you in advance.
