I just got the new modem from Charter to upgrade my internet dl speed from 60 mbps to 200 mbps. When I connect my computer directly to the modem with an Ethernet cable I get the full 200 mbps. However, via wifi on the R6300v2 router, I'm still restricted to 60 mbps even though the router is supposed to be capable of 1 gig mbps speeds over wifi. Is there a setting I must change in the router to get the faster speed on my wifi or what?
