I currently have a Motorola SBG6580 Modem/Router with a Netgear WNR1000V3 as an access point sitting right next too it. This is how I have them configured: The Motorola is my modem/5ghz router, it is broadcasting myssid_5ghz and a guest 5ghz wifi network and DHCP for both. The Netgear is doing 2.4 with no DHCP and 2.4ghz broadcasting my normal SSID (basically a 2.4ghz access point) it also will have a Trendnet TEW-737HRE extender connected to it but currently isn't because it is on the way.The reason I have them like this is because the Motorola is provided by my ISP and the Netgear I had laying around. So instead of spending $100 on a router I set them up like this. My question is the Motorola can only do N-5ghz and I was wondering if the AC upgrade was worth it. I only have a few devices that can support N-5ghz which I know of including: my ipad mini 1st gen, Moto X, and Droid Ultra with the Moto X and Droid Ultra supporting AC also. The rest are all 2.4ghz. At most times I have anywhere from 10-25 devices connected to my Wi-Fi network including a home media server which is of course connected via a CAT5e cable. Also my internet connection is only 6mbps down from my isp which I do get all of the time. I would use AC for range and streaming from my media server the only devices I know of that could support 5ghz ac on my network is the Moto X and Droid Ultra but they are two of the main devices. Thanks in advance for all help and suggestions.
