Modem to router speed slower than Modem to PC speed - RP614v2

Thanks for the advice on the MTU. I did the same process you did and then checked my MTU in WAN and it was already set correctly(to 1500). I think the router should make a big difference. Will let you know. I have an Asus RT-AC3200 for my wifi currently. Was going to get the Nighthawk but man that is very expensive. This 3200 makes a huge difference though and I can walk around outside almost 100yds from my house and still be connected. Very happy with this. Now I just need a wired router and thats were the AC68U comes in to replace this ancient RP614.
