Why is my DSL speed so bad?

4 years ago I would have 3 people playing wow with very little lag. Noe for the last 2 years its just been me here and the lag is really bad when ever I try to download a game update, and even when I'm just using discord and roll 20. I did a spead test and don't see to get above a 2.6 download speed an a  0.7 upload spead. Fios is unavaible in my neighborhood. Hey Verizon can you help? or do I need to go to switch to cable?
