I own a Surfboard SVG2482AC, getting downloads around 200 but xfinity plan should go up to 1200 mps . I have no issue with service but am clearly overpaying for service I am not receiving. Xfinity is blaming the modem (it is 3.5 years old) saying I should use their modem as they will always keep it updated.
How do I know if it really IS my modem and if I should purchase a new modem, or if it is their service? I only discovered this issue when trying out Verizon 5G service and comparing speeds online, so I do not know if it has always been this speed or not. (disclaimer- This was put in by our builder/tech division and I am not super techy so please explain to me like a toddler :)
