No High Speed as promised comcast

can someone please confirm? an xfinity tech came to my house and told me that my comp did not handle High speeed internet - It is lenovo desktop connected ethernet  to the modem - Xfinity keeps advertsing High Speed Internet but they can not get more than 300 mbps at my house - I starting to believe what ATT says about comcast can not delivery high speed - I watched movies on my fire stick and it is so slow and buffered 4 times almost 2 o 3 minutes. Do not know what to believe anymore - I tried to contact comcast but honestly those techs are horrible - they told me I needed ficr optics to get High speed - the tech came and only told me that was my computer - which there is nothing wrong with my computer. HELLLPPP
