Does Buying A New Modem Increase Internet Speed Link

: Modern cable internet relies on DOCSIS 3.1 technology, which handles higher bandwidth and more data channels. Upgrading from DOCSIS 3.0 to 3.1 can "unlock" your plan's full potential.

: If your ISP has upgraded its local network infrastructure, your older modem may no longer be optimized to communicate with their systems efficiently. Common Limitations Does A Router Or Modem Affect Internet Speed? - Astound
