So to preface, I'm very familiar with networking and I've tried all the troubleshooting that I could think of on my end before reaching out here.
LEAD UP TO THE CURRENT ISSUES:
I just moved and transfered my service, and the tech came out and setup my internet and replaced my XB3 to the XB6 when the tech was setting up my internet. We tested the speed while the tech was there, and at the time I was on the 250mbps plan, and had no issues.
About a week or two after the internet was setup, and I was all moved in, I decided to check out faster speed offers, and ended up upgrading to the 1000mbps plan as I now had the XB6 that is supposed to support said plan.
(TO CLARIFY, I'M NOT EXPECTING 1000MBPS DOWNSPEEDS, BUT I SHOULDN'T ONLY BE GETTING HALF OF THE MAX)
ISSUE #1 (WIFI DOWNSPEED HALF OF WHAT IT SHOULD BE):
Currently using 5GHZ on my thinkpad p52, my NVIDIA Shield 2017, and various other 5GHZ devices, I average a downspeed of only 415-485mbps as show below:
ISSUE #2 (ETHERNET CONNECTION CAPPED AT ONLY 90mbps down)
I've tried testing ethernet speeds from the XB6 over cat5e and cat6 ethernet cables and they seem to be capped at 90mbps for some odd reason (The ports on the XB6 are flashing green, not orange so it's not setting it as 100mbps). I have done a factory reset on the XB6 and this still has not fixed the issue. I get the same results on my NVIDIA Shield ethernet, my Thinkpad P52 ethernet, and various other ethernet capatable devices. So it's leading me to believe that there were multiple provisioning issues after I did the internet speed package upgrade online, and also that the tech did not properly provision my upgrade from the XB3 to the XB6.
ISSUE #3 (MY XFINITY ACCOUNT STILL SHOWS THE XB3 AS MY DEVICE)
For some strange reason my xfinity account shows that my device is still the XB3 when my xfi app is showing that my device is the XB6, so this again leads me to believe that the provisioning of both the XB3 to XB6 upgrade and the faster internet package upgrade have partially failed to complete or sync.
I wanted to make sure that the image wasn't just a standard default image to represente all routers/modems, so I verified the URL and image meta data. It shows that the image uses the specific XB3 device name, leading me to assume that xfinity is indeed assuming I still have a XB3 setup on part of it's system:
SUMMARY OF TROUBLESHOOTING PERFORMED:
- XFINITY reset signals
- Multiple power off and on cycles of all equipment and XB6
- Factory Reset of the XB6
- Manually adding the XB6 in the xfi app
- Delete existing profiles for eth0 and wlan0 on my Thinkpad p52, and reset network connections
- Confirmed the MTU values are at 1500 for eth0 and wlan0
- Confirmed all coaxil connections are secure
- Performed dozens of speed tests at various distances from the XB6 over the 5GHZ, on various devices, and various speed test providers (Xfinity, speakeasy, etc) to make sure it wasn't an isolated speed test provider issue.
- Performed dozens of speed tests, on each XB6 ethernet port, on a multitude of speed test providers (Xfinity, speakeasy, etc) to make sure it wasn't an isolated speed test provider issue
- Confirmed that each of the CAT5e & CAT6 cables were not showing up as a 100mbps connection by checking to make sure the port LED on Ports 1 & 2 displayed green when an ethernet connection was established.
- Tried speed tests on both ethernet and 5GHZ on multiple operating systems including windows, mac os, and Linux (debian and ubuntu)
I WOULD LIKE THE FOLLOWING TROUBLESHOOTING TO BE PERFORMED BY XFINITY:
- Verify that my account is properly setup and that my XB6 is in deed provisioned properly, and possibly address why the xfi app shows my XB6, while xfinity.com shows my devices as the XB3.
- If number one wasn't the cause of these issues, please run diagnostics on my local neighborhood node to make sure there isn't issues arrising from that.
- If nothing can be figured out remotely, I'd like to request a technician to come out and figure out a solution. I WOULD ALSO REQUEST ANY TECH FEE TO BE WAIVED AS I HAVE OBVISOULY TRIED EVERYTHING SO FAR

@ComcastMorgan I saw you had experince helping run a node healthcheck to another user who has a similar 90mbps downstream issue via ethernet so maybe you could help?
***ALSO IF I TRY RIGHT NOW TO UPGRADE AGAIN TO ANOTHER PACKAGE, IT SHOWS THAT I NEED TO UPGRADE MY DEVICE....I AGAIN HAD THE TECH TAKE MY XD3 AND INSTALL A NEW XD6 WHEN HE SETUP MY INTERNET AT MY NEW ADDRESS. I ONLY HAVE SERVICE AT ONE ADDRESS, SO MAYBE DURING THE ADDRESS CHANGE THE ACCOUNT DIDN'T GET PROVISIONED PROPERLY?***
