speeds

I don’t understand much of this I have a max transit cat 18. I have had it for about a year I am trying to determine if at&t is slowing me down or I have a mother problem. I am getting on Speedtest 80 down through the pep wave 98 down on 5g. on the usage report aggregate and cellular getting 6. the problem is every thing I am using computer Apple TV and iPad seem to be running slow.Thanks for any info

speedtest at fast.com , that will show you if your carrier caps streaming sites. if you see like 2.5mbps, or 5.0 flat, thats the case with almost all plans.
