I just came from the xFinity store where I signed up for my internet plan speed Extreme 250 Mbps (via Extreme added to Additional Services). I was told to and did power off my modem (I have my own), waited 15 minutes and powered back on. However, my speed test is still only 115 Mbps, same as it is each day and every day I've tried for a week now.
Can someone help, cause I'm not even anywhere close, or even up to HALF of what I'm supposed to be receiving? I have a Motorola MB7220 Comcast DOCSIS 3.0 (rated to 300Mbps)
Is there also a router in your setup ?
