Signal levels / truck roll / plant issue / maintenance

@ComcastCares (Really?)

 

I upgraded from 200Pro Plus/Double Play and added Gig, went and bought a SB8200 modem of my own, provisioned it on your network and got terrible speeds of 150mbs (15% of Gig), wired direct to my pc which I have iperf tested to run at gig speeds over local switches.

 

Troubleshot repeatedly with tech support who would basically reboot my modem, ending chat support session (What a convient way to get rid of your customers), finally was able to speak to a rep and was "escalated" to tier 2 whom proceeded to reboot my modem several times to no avail and ultimately suggested trying the new X7 cable modem from Xfinity, I got it today and what do you know same terrible speeds. Call back in and get put through the run-around again hung up on several times, chats disconnected by reps rebooting my cable modem, and my speeds are still trash. 

 

Im supposed to get a "call" tommorow from a "Virtual Tech" which Im certain will just be the automated system rebooting my cable modem once again (Not fixing the issue)

 

Since Ive had 2 seperate docsis 3.1 cable modems both run at 150Mbps *MAX* (Again 15% of what I am paying for which is unaccetable), their is obviously a plant issue or something in the head end. (Both 3.1 modems have been re-provisioned several times)

 

I setup my brothers Gig, and he is getting close to 890Mbps, which is much more reasonable.
