Possible your router can't handle gigabit. Or just the wi-fi.

I'm plugged direct into the modem, everything else is wireless to the fiber connection. I'll start looking into tweeks. First thing I need to see if they (internet company) let me into the modem. The installer didn't provide a username and password and the only default one I could find online for that modem didn't work.
