They always attenuate speeds no matter what. My lad gets ~60 on our 200 package (and his Solwise PA's have gigabit ports.
TP-Link AV1300 covers a few "models" - which one is it and does it have 1GB ethernet ports - if not and they are 10/100 - then the max speed (before the maims attenuation) will be 100mbps.
