New Boston, NH
Rebooted my modem this morning, and noticed upstream bonding for the first time. (New Boston, NH)
Speedtests afterwards seem to show some change in my download speeds. Have Extreme 50 - always go about 62mpbs prior to today. Best I've seen today is about 52mbps using closest speedtest.comcast.net server (Boston). Will watch / see if that changes at all.
