My ISP speed is 120mbps. When connected directly to my modem, my speed runs at upwards of 100mbps. However when connected through my router, (either wired or WiFi) my speed is right around 10mbps. I have a brand new Netgear Nighthawk AC2300, Model: R7000P router. I spoke to a Netgear agent who suggested I change the channel on my WiFi connection which did nothing. He also said the WiFi vs wired may result in up to 30% less speed. 10mbps out of 100 is 90% less though. That seems like a big difference to me.
