Slower wifi speed with Asus RT-AC68U.
I have the 120/20Mbps plan and I use my own router Asus RT-AC68U (AC1900).
I noticed that my wifi speed is slower than when I use the Fizz box only. I have around 70/80Mbps in download and the upload is fine (around 20).
I have done a full reset/reboot on both my Fizz box and router but I still have have the same speed issues...
What is the best setup configuration for this Asus router?
Thank you for the help.
