Why do I pay for 100Mbps and get 80Mbps?

Nothing else is connected to the network right now and speed test reads at 80Mbps, instead of the 100Mbps I pay for.  There is no wi-fi used. Only Ethernet cables.

Tested without router in circuit and got 100Mbps. Will buy a newer router and see if it fixes the speed issue.

Does your computer's ethernet network adapter support 10/100/1000 (gigabit) speeds ? If not 80 is what is to be expected due to the normal overhead.

I think if you read the description, you might find it says 'UP TO' 100 Mbps, nothing about 'guaranteed'.

Thank you for representing the comcast lawyer's opinion. However I am actually for solving this problem. Pehaps this is similar to the BTU rating on portable air conditioners. They were so inefficient that a new equivalency BTU rating was established to more accurately represent the comparable normal wall mounted/central  air conditioner BTU rating.

Newer router didn't fix speed issue.
