Recent upgrade, speed unchanged
I became a customer about a year ago and signed up for the 300Mbps ("Do More" plan at the time?). I purchased my own Arris SB8200 (v2 apparently) on Amazon. Typical speed test gave me the expected 350Mbps down and 20Mbps up or so. I then got the automatic upgrade back in March I believe and my speed was bumped up to 400Mbps down and 35Mbps up. Typical speed tests of about 440Mbps down and 38Mbps up.
Anyway, my $35/mo (after discounts) 1-yr promo was ending soon, so I logged in yesterday to see what my options were. I see now that unlimited data is available with the new plans and customers are allowed to continue using their own equipment. Wonderful. So last night I opted to just upgrade to the 1Gbps w/ unlimited data and the 5-yr price guarantee. Not too bad of a deal if you ask me. I got the email fairly quickly that my new service with unlimited data was now active, reviewed the upcoming billing, etc. However, my modem never rebooted. I left it alone for the night. I rebooted it this morning and I'm still seeing about 440Mbps. I gave it a power cycle at lunch and unfortunately I'm still seeing the same speed, like it hasn't been provisioned for my new plan yet. Am I just being impatient?
I'll also note that my drop is a bit on the longer side and the tech did have to install the Evo preamp. My understanding is that the SB8200v2 should be capable of 900Mbps+ down and the SNRs I see here should be capable of that. Or am I wrong? I'll admit my DOCSIS knowledge is limited. I guess I kinda just expected to see 600Mbps or better.

The SB8200v2 is not compatible with Gigabit internet service. Comcast/Xfinity rates it for wired download speeds "Up to 936 Mbps". Follow the "See all modems" link near the bottom of https://www.xfinity.com/support/internet/customerowned and then under the "Compatible Modems" heading click the Arris list. Using devices on Internet speed tiers for which they are not approved tends to produce unexpected results, often speeds well below the ones you are paying for.
AFAIK Comcast/Xfinity has never said how they provision devices operating on speed tiers they're not approved for. All I can tell you is that many customers who tried it have reported that they don't get full speed. There's a tendency to think the device will operate at the maximum speed it is capable of, but that doesn't seem to be the case.
