Modem provisioning issue and speed mismatch

ever since i upgraded my plan to the highest tier i have been noticing issues and it seems like customer service and the techs don't really understand. When i upgraded the website showed symmetrical speeds of 2000Mbps then after i upgraded i was sent the attached summary, which clearly states those speeds. Now the app is stating that i only get 250 Mbps and the website says 300 Mbps, so I'm trying to find the disconnect. However, my main issue is there is some sort of bug on Xfinitys end with the modem provisioning where there is a hard cap on my upload speeds at exactly 40 Mbps, I had a tech come out and test the speeds, i have gone into my modems admin page and confirmed everything is configured correctly. i keep getting assured everything is working correctly but thats hard to accept when the speed im getting is 8% of the speed im getting to the outlet and 2% of the speed i was told i would receive. there is something off here and its the principle at this point.

user_xkclt5 I can definitely understand why this would be frustrating, especially after upgrading and being told to expect much higher speeds. You’ve already done a lot of the right troubleshooting steps, and I agree with you that something doesn’t seem to be adding up here. I’d like to take a closer look at your account and the provisioning details so we can really get to the bottom of what’s going on. Please send me a direct message with your full name and service address, and I’ll dig into this with you. We’ll review everything together and work toward getting a clear answer and a proper resolution.

I couldn’t figure out how to dm you directly but I still need some assistance. They pushed a new bootfile - this made my upload a lot better 300ish (still not 2000 but i was happy bc its alot better than 40). But now my download is won’t go over 1000mbps (2000 previously). I checked SNR and it good sitting at around 41dbs. Let me know what you need from me to help fix this

It was a bootfile error, they had to repush the correct bootfile. Took me awhile to get to the correct customer service person, but they were able to fix some of the issue. However I think they still pushed the wrong file because my upload is fixed but my download is now having issues
