I just got sonic installed and I got the router from Sonic. The speeds are clocking in at 300Mbps for both upload and download. The ping is amazing so I am happy with it, but I'm wondering how I could make use of the full (or close) gigabit? The person who installed it said I need to be connected with ethernet, but I was wondering if this was a limitation on the router? If I were to buy a new gigabit router that can handle higher speeds would I see closer to the Gigabit on WiFi?
