Hello. Cablevision Optimum is directing me to you. I am hoping I don’t need a new modem since I recently bought an Arris Surfbiard. Today I requested that Optimum increase my Internet speed to 300 MBPS, which they did and will start charging me for it. But the speed test does not show 300 Mbps for the download which it should, according to Optimum. They said my speed is fine on their end and directed me to the modem manufacturer. When I went on your website, I don’t see the product number of the modem that I bought. I’m trying to determine if I have to get a new modem or not. This is the p/n: SBG00DAY20RT. is this compatible? According to the optimum site I can use a DOCSIS certified DOCSIS 3.1 modem for all speeds.thank you for any guidance
Cablevision Optimum says my modem (arris surfboard) is the issue

The model number is G20. I decided to disable this modem and go with the optimum modem. I would be interested in hearing the reply though. So I know, for the future
When checking internet speed, keep in mind that results can vary depending on the device you're using.
To see if your gateway is delivering the correct speed, try connecting a computer directly to it using an Ethernet cable.
This type of connection gives the most accurate speed test results and can show the at most speed of your subscribed internet plan.
Additionally, the 5 GHz Wi-Fi band offers faster speeds but shorter range, while the 2.4 GHz band provides better coverage with slower speeds.
