Before changing mode
Model-specific SAX/SBE/CBE specs and app controls are not verified in this pack. Do not substitute a generic modem approval list for exact model/speed-tier eligibility.
- Identify the gateway model and any TV or voice service on it.
- Record present cabling and Wi-Fi names.
- Confirm the provider’s recovery procedure before switching modes.
Check the result
After one change, verify a wired client, Wi-Fi clients, and any TV or phone service. If service disappears, restore the recorded mode and cabling.
