I use a powerline adapter in order to use my PC and I recently upgraded my speed via Spectrem. Due to this they sent me a new modem and router and after setting it up and activating them, the powerline adapter gets little to no speed. Before the change I would get around 90 mbs if I did and speed test and now I am getting 8. The internet itself is faster as I have tested it on my laptop. I have reset the powerline adapters multiple times, changed outlets, tried all available ethernet ports on the back of the router, all to no improvement. The adapter is a TP-Link AV2000 and the router is whatever the router is that Spectrum gives you, Model: SAX2V1S.
