I'm in a rental apartment with Comcast as provider. I have their regular home service. Upstaris PC (through ZyXEL powerline) fluctuates from "Very Slow" (1-3 Mbps) to "Good" (17 Mbps), with no obvious reasons for the change. I know powerlines are finicky and that is likely the source for the slowness. Questions now are: 1) Ditch the powerline and add a PCIE wireless card to upstairs pc? 2) Or hire an electrician to wire up the house for ethernet in the walls? PICE card will be around $100 (or less), but subject to connection issues and a less secure connection. Electrician will probably be a few hundred. Any thoughts from the experts?
