slow internet speeds on gigabit speeds with motorola sb8200 and comcast modem CGM4140COM

So I'm having speed problems. Tech came out today, ran a new line to my Arris SB8200 modem which is connected to a netgear Orbi mesh router. Best speeds we could get on wifi and directly wired from modem to computer were around 490Mbps. Tech then swapped out my SB8200 for the comcast Technicolor modem, model CGM4140COM and performed the same test and recieved the same speeds, maybe 30-40Mbps to the better for around 520Mbps. I am using Cat6 wire from modem to Orbi and when tested directly to computer Cat6 as well. Please tell me where to proceed. I have read here that the Netgear CM1000 is a good choice as the phone is of no use to me on the comcast nmodem.
