A multi-gig cable-modem buying guide for the S33, including DOCSIS 3.1, its 2.5GbE plus 1GbE port layout, ISP approval risk, and why a separate router is still required. This UK edition adds exact regional model, compatibility, seller, delivery, warranty and return checks.

Quick answer for UK buyers
S33 is the disciplined modem upgrade when a cable plan can exceed gigabit and the router WAN port can actually use 2.5GbE. It is not a Wi-Fi upgrade by itself. For United Kingdom, verify the exact regional offer separately rather than assuming the US model or bundle is identical.
Use the main research and country edition together
The original page remains the evidence base for the practical decision. This edition adds the model and checkout details that can differ in United Kingdom.
Match the exact UK model
A shared product name can hide different model numbers, wireless bands, plugs, power supplies, dimensions, materials, bundles or app features. Compare the selected UK offer with current manufacturer documentation.
Check the complete landed offer
Confirm GBP price, seller, delivery, included hardware, regional warranty, return handling and current availability. The main risk from the research is: No router or Wi-Fi functions
