UK workflow

Before replacing a UK ISP hub, check these six things

The Wi-Fi standard on the box is rarely the deciding factor. Start with the access technology and WAN requirements.

1. Is it FTTP or FTTC/SOGEA?

FTTP normally gives you Ethernet from an ONT. FTTC/SOGEA can require your replacement device to include a VDSL modem.

2. What WAN authentication does the ISP use?

PPPoE is common on several UK profiles. Sky can require line-specific DHCP/MER behavior instead.

3. Is VLAN configuration needed?

Some DSL profiles use VLAN 101 while some FTTP profiles explicitly do not. Never copy a VLAN value from the wrong access type.

4. Does the router support the exact special option?

For Sky, DHCP Option 61 can matter on some lines. Brand-wide claims are unsafe; verify the exact model/firmware.

5. Do you need Digital Voice or ISP TV?

Hub-dependent phone or TV features can turn a direct internet replacement into a keep-the-hub topology.

6. Is AP/bridge mode actually the better goal?

If you mainly want better Wi-Fi, keeping the ISP box for access/authentication and using your mesh as an AP can be simpler and more supportable.
