I use Cox Cable in Vegas, and they just upgraded my 100mbps connection to 150. Well, my old modem maxed out at 100, but I have an Arris SB6182 lying around that can hit 150, so I swapped them out. Told Cox, they activated new modem, works well. Wired modem to computer directly, 170/180mbps top speed. But then when I connect it through the lan on my router, I drop to around 40mbps. Previously, this same router was giving me my 100mbps with the old modem. What do?? Please help!
