Switched from CM3000 to CAX80 and it destroyed upload/download speeds

So I recently moved to Benicia, CA and signed up for the 2Gbps download 300Mbps upload package Xfinity offers. At first I got the CM3000 just missing the fact that it only supported 1Gbps but ran a speed test and got what I was expecting (941Mbps down and 358Mbps up). I decided to get the CAX80 since it has the 2.5Gbps port and I wanted the Wifi. So I replaced the the CM3000 with the CAX80, registered it with Xfinity, went through the set up process using the Nighthawk app and now I'm getting worse speeds (700Mbps down, and 5.88Mbps up). I haven't changed my set up in any way other than doing this. What's going on?

So to reiterate (ran these tests multiple times on both modems):

CM3000: 941Mbps down and 358Mbps up
CAX80: 700Mbps down (1.34x slower) and 5.88Mbps up (60x slower!)

CAX80 Firmware Version: V5.1.1.8
CAX80 Cable Firmware Version V1.02.08

OS: Windows 11
