Re: Internet Speed 400 mbps Problem

Fot the last 7 years I’ve been on Blast 150MPBS and only until recently have we begun to have issues w/internet. Yesterday I decided to call because
(Like I have an extra 3 hours to waste with your support people). I do have my MacBook hard wired to the Xfinity router as well as my Sonos. The router I now have is from comcast the xFi Advanced gateway Technicolor CGM4140COM. I have done speedtest after speedtest and I am not getting even close to 400 mbps. Matter of fact its significantly less than what it was before, not even reaching all areas of the home! Topping out at 78Mpbs. Before I was getting anywhere from 125 mbps to about 150mbps. Thats hard wired. If I do a speedtest on my laptop using wireless im getting 75 mbps. Could anyone here explain why this is? If Im paying for 400 mbps, I want 400 mbps.

Try callingl 1-800-comcast and ask a rep to completely remove the modem from your account and to "re-provision" it from scratch. Also ask them to confirm that the provisioning and account data in their database is correct and complete and that the correct configuration / bootfile for your subscribed to speed tier is being pushed to the modem.
