The Sky Hub does a reasonable job for most households, but nothing about a Sky broadband contract requires it to stay plugged in. The service runs over shared national infrastructure rather than Sky-only wiring, and a third-party router can connect once the line type and the authentication method are both correct. This guide covers the line types, the settings that matter, the swap itself, and the caveats worth knowing before the hub gets unplugged.
Sky broadband works with a third-party router, since the service runs over the Openreach network, or Sky's own full fibre in places, rather than proprietary wiring. Full replacement of the Sky Hub needs a router supporting Sky's DHCP Option 61 authentication, mainly ASUS or Netgear, with other routers running behind the hub. Note the line type, check Sky's current own-router guidance, and keep the hub if Sky Talk or a Sky TV product needs it.
Key Takeaways
- Sky broadband runs on the Openreach network, or Sky's own full fibre in places, so a third-party router is never blocked outright, though Sky only supports troubleshooting on its own hub.
- Full fibre lines connect a router straight to the ONT; FTTC lines need the VDSL modem the Sky Hub carries, and no Sky Hub has a bridge mode to hand that job over cleanly.
- Sky authenticates with DHCP Option 61 rather than PPPoE, so there is no standard username and password, and only ASUS or Netgear routers typically support it.
- Noting the current settings, swapping at a quiet time and testing wired before wireless keeps the Sky Hub as a fallback throughout the process.
- Sky Talk and some Sky TV products such as Sky Q, Sky Glass and Sky Stream are built around the hub, so check those before removing it from the network.
Sky broadband does not lock you to the Sky Hub
Sky delivers home broadband over the Openreach network across most of the UK, with Sky's own full fibre build reaching some areas directly, and the Sky Hub is simply the router Sky posts out to make setup straightforward. There is no proprietary Sky-only wiring and no hardware whitelist stopping another router from connecting, provided that router matches the line type and the way Sky signs the connection in.
The honest catch is support. Sky troubleshoots faults on its own equipment, so a call about a dropped connection while running a third-party router usually starts with a request to plug the Sky Hub back in. That is reasonable rather than obstructive, since it is the fastest way to tell whether a fault sits on the line or in the replacement hardware. Other Openreach-based providers work the same way, and the guide to using your own router with any UK ISP sets out where Sky sits next to BT, EE and Plusnet on this.
Your line type decides where the router plugs in
Everything about the swap depends on whether the Sky line is full fibre or part fibre.
On full fibre (FTTP), Openreach or Sky's own network fits a small box called an ONT on the wall, and the fibre ends there. A router with an Ethernet WAN port connects to the ONT's LAN port directly, and the Sky Hub becomes optional at that point, subject to the authentication caveat covered below.
On FTTC, the connection arrives over copper from a street cabinet and lands at the master socket. Signing in on this kind of line needs a router with a built-in VDSL modem, since there is no ONT doing that conversion. The Sky Hub carries this modem internally, and because no Sky Hub has a bridge or modem-only mode, there is no clean way to hand that job to a separate router the way full fibre allows. The workable setup on FTTC is to keep the Sky Hub connected to the socket, turn its WiFi off, and run the new router behind it handling the WiFi and the rest of the home network.
Checking which line type is in the house is straightforward: an ONT on the wall with a fibre light means full fibre, while a hub cabled into a phone-style master socket means FTTC.
Sky's settings differ from most providers
Most UK broadband runs on PPPoE, a username-and-password style login. Sky does not. Sky authenticates with DHCP, often labelled IPoE, using a method called MER or DHCP Option 61, and the how to use any router with EE broadband guide shows what the more common PPPoE pattern looks like on a similar Openreach line for comparison.
A router capable of fully replacing the Sky Hub on full fibre needs to support Option 61 specifically, which in practice narrows the field to ASUS and Netgear. On a compatible router the IPv4 connection type is set to DHCP, the Option 61 client string is entered as anything@skydsl with anything used as the password, and VLAN tagging is left off. Some newer full fibre and CityFibre-based Sky lines connect on plain DHCP with no Option 61 string required at all, but which method a given line needs cannot be known for certain in advance, so checking Sky's current own-router guidance, or the connection details in the Sky account, before buying anything is the sensible order of operations. Rather than inventing a single universal setting, treat this section as the shape of what to expect and confirm the specifics against Sky's own documentation.
Before any of the old network is unplugged, it is worth logging into the existing hub to note its current WiFi name and password, so devices reconnect to the new router without retyping anything on every phone and laptop in the house. The Sky Hub login guide covers the 192.168.0.1 address and where the admin password is printed on each hub model.
The swap, step by step
With the line type confirmed and the settings noted, the swap itself is a short job that stays low-risk because the Sky Hub remains a working fallback throughout.
- Note the settings. Record the Sky Hub's current WiFi name and password, and confirm from Sky's current guidance whether the line uses Option 61, plain DHCP, or needs the hub kept in place on FTTC.
- Pick a quiet time. A weekday mid-morning causes less disruption than an evening with the household relying on the connection.
- Connect the new router. On full fibre with an Option 61-capable router, cable the router's WAN port to the ONT's LAN port in place of the Sky Hub. On FTTC, or with any router that lacks Option 61 support, leave the Sky Hub connected to the master socket or ONT and cable the new router into one of the hub's LAN ports instead.
- Configure the connection. On a full replacement, set the IPv4 protocol to DHCP and enter the Option 61 details from Sky's current guidance. On a behind-the-hub setup, run the new router's own setup wizard and switch the Sky Hub's WiFi off so only one WiFi network is broadcasting.
- Test wired first, then wireless. Confirm a laptop on Ethernet gets online before checking WiFi coverage around the house.
- Tidy up. Reusing the old WiFi name and password lets phones, TVs and smart devices rejoin automatically. Box the Sky Hub rather than disposing of it.
If the new router will not connect, plug the Sky Hub back into its original position, confirm the line itself is working, and revisit the connection settings before trying again.
The caveats that catch people out
The technical side of the swap is the easy half. These are the details that actually cause problems.
Sky Talk runs through the hub. Sky's landline service plugs into the phone port on the back of the Sky Hub, not into the ONT or the master socket. Removing the hub from the network disconnects the landline, so anyone using Sky Talk should keep the hub in the chain, generally with its WiFi switched off, or check Sky's current guidance before making any change.
Some Sky TV products expect the hub on the network. Sky Q, Sky Glass and Sky Stream can have their own network requirements, and it is worth checking Sky's guidance for the specific box in the house before the hub disappears, particularly if it currently talks to the hub for updates or a second-room connection.
Keep the hub for support calls. Sky troubleshoots faults on its own equipment, so boxing the hub rather than getting rid of it is worthwhile. Reconnecting it briefly during a fault report is the fastest way to confirm whether an issue sits on the line or the replacement router.
None of this makes the swap a bad idea. It simply means Sky Talk users and anyone on certain Sky TV products need one extra check before the hub comes out, and that the hub itself is worth a shelf in a drawer rather than the bin.
The router worth buying for a Sky line
A full buying guide is not necessary here, but the default pick for running an own router on Sky is worth naming. The ASUS RT-AX86U Pro supports the DHCP Option 61 authentication Sky needs for a full replacement on full fibre, connects to the ONT over a 2.5G WAN port that suits Sky's faster tiers, and its WiFi coverage and device handling comfortably outperform the stock hub whether it ends up replacing the hub outright or running behind it on an FTTC line.
