Upgraded but not getting speeds

[Otisboat]

Hello, I just upgraded from performance around 3pm 5/20/20 (100mbps) to extreme (300mbps) Online. After upgrading, modem reset about every 30 minutes on its own and it now remaining on. I am not receiving new download speed ONLY upload speed of 20mbps instead of 5mbps. I have a TC-7610 which Xfinity says it can do 270mbps download. How long does it take to get new download speed? I have reset multiple times but keep getting my prior 90 down wired and 80 down WiFi. Any advise is appreciated. Thanks,

If you look at the website don’t look at the speeds your modem can possibly achieve, look at the plan it’s approved for. It’s approved for, 200 not 300. Then factor in your model router and it’s capability , then factor in the equipment your testing speeds with, does it even have the capability to go over 100? First things first though, your modem isn’t the proper one for your plan

I understand it isn’t the recommended modem, but if it is recommended for 200mbps then I should at least be getting a boost that would reflect that? I’ve been told by Xfinity that I should expect 80% of my speed wired and 60% WiFi which I have found to be fairly accurate. So following this principal, on my wired connection I should be seeing at least 160 down? If this is an issue with router than I will purchase better one but if I buy a new router and it doesn’t resolve anything than what’s the point? I just figure I should see some bump especially since the upload has increased 15mbps but download has remained same?

That’s not how it works in reality, if you provision a modem for the wrong package, you get a way slower speed, not the next step down in speed. Get the proper modem. Again, What are you testing hardwired speeds with and can it go over 100? Can’t stress the importance of having the correct modem first
