Use Your Own Router With Any UK ISP
Wanting a better router feels like one decision. It is actually four, and picking the wrong one is exactly why people end up stuck with a strict NAT, dead WiFi in the back bedroom, or a setup that half works. The right choice depends entirely on your ISP and whether you are on cable or full fibre.
We have done this swap across Virgin, Sky, BT and EE lines, so here is the honest map. We will walk through the four setups, explain the one trap they are all quietly trying to dodge, lay out the real per-ISP picture, and point you to the exact step-by-step for your provider.
Key Takeaways
- Using your own router is not one decision; it is choosing between modem mode, bridge mode, access-point mode, or leaving the hub as-is.
- Only some UK hubs become a true modem; Virgin's Hub 5 can, while Sky, BT and EE hubs cannot.
- Double NAT is the real problem most of these setups are trying to avoid, and it mainly hurts gamers, port forwarding, VPN servers and smart-home kit.
- On full fibre the missing modem mode matters far less, because a capable router can usually talk straight to the Openreach ONT.
- A new router gains you coverage, control and a cleaner NAT, but it never raises the line speed your package sells you.
You have four options, not one, and the wrong one is why people get stuck
Before any kit decision, get the four routes straight in your head. Everything else hangs off them.
- True modem mode (bridge on the hub). The ISP hub stops routing and hands the raw connection to your router on one LAN port. One device in charge, full control.
- Bridge mode on your own router. When the hub refuses to step down, you flip your router into a mode where it stops routing instead. Useful in narrow cases, but it does not remove the hub's NAT.
- Access-point (AP) mode. Your router or mesh does WiFi and switching only; the hub keeps routing. Great coverage, no double NAT, but you lose router-level features.
- Leave the hub as-is and add kit. Plug a second router or mesh in behind the hub and let it make its own network. Easiest, and the classic cause of double NAT.
One fact decides most of it: only some UK hubs can be turned into a real modem. Virgin's Hub 5 can. Sky, BT and EE hubs largely cannot, so on those you either compromise behind the hub or, on full fibre, bypass the hub entirely at the Openreach ONT.
Set the expectation honestly too. None of this makes your line faster; your package speed is your package speed. What you gain is coverage, control, and a cleaner connection for gaming and hosting.
Modem mode vs bridge mode vs access-point mode vs leaving the hub alone
True modem mode is the gold standard. The hub becomes a dumb modem, your router does the routing, and there is no double NAT. The Virgin Hub 5 is the headline UK example, and we cover the exact toggles in our guide to putting the Virgin Media Hub 5 into modem mode and using your own router.
Bridge mode on your router is the workaround for when the hub will not budge. Your router stops routing, which can help in a few specific chains, but it does not remove the hub's NAT, so know what it does and does not solve before you rely on it.
Access-point mode is the realistic answer for hubs that refuse to bridge, and for the Virgin Hub 5x. Your router or mesh handles WiFi while the hub keeps doing DHCP and routing. You get excellent WiFi and avoid double NAT, but you give up router-level extras like custom QoS and a VPN client or server, because the hub is still the boss.
Leaving the hub as-is is the no-config option. It is the easiest, and it is exactly what creates double NAT, so only do it knowingly.
A quick decision cue. If you want full control and one device in charge, choose modem mode where your hub supports it, or the ONT route if you are on full fibre. If you just want coverage with zero hassle, choose access-point mode. That single choice threads through the rest of this piece.
Double NAT is the trap most of these setups are quietly trying to dodge
Double NAT, in plain terms, is two routers in a chain both handing out private IP addresses and both doing NAT. It happens the moment you plug a second router behind an ISP hub that is still routing.
Most people never feel it. The ones who do are console and PC gamers (hello, strict or moderate NAT type, broken party chat and failed hosting), anyone running port forwarding, a VPN server, security cameras, smart-home hubs, or remote access into the house. Casual browsing and streaming usually sail right past it.
The fix-order ties straight back to the four options. Best is removing one NAT layer entirely: modem mode on the hub, or your router straight to the ONT. Next best is access-point mode on the second device. A DMZ is a last resort with security trade-offs. For the full how-to-detect-and-fix, see our explainer on what double NAT is and how to fix it.
Virgin Media: the only big UK ISP with a clean modem mode (with one Hub 5x catch)
Good news first. Virgin's cable hubs (Hub 3, Hub 4 and Hub 5) have a long-standing, reliable modem mode. Flip it on, connect your own router to LAN port 1, and the hub becomes a plain modem. It is the cleanest own-router experience in the UK.
Now the catch, verified for 2026. The Hub 5x, the XGS-PON full-fibre and nexfibre unit, still lacks a dependable modem mode across much of the footprint. Where it appears at all, people report drops. On a 5x the practical answer is a mesh in access-point mode behind the hub.
Two port notes worth knowing. The Hub 5's 2.5Gbps port matches the RT-AX86U's 2.5G WAN, though a known Energy-Efficient Ethernet (EEE/802.3az) conflict can drop some 2.5G links to 1Gbps until EEE is disabled on the connected device. The Hub 5x has a 10G port, but that is wired headroom, not a WiFi win. Whatever you do, check the Connect app for the Modem Mode option before buying a router, especially on a 5x.
For the full step-by-step and the which-hub detail, see the Virgin Media Hub 5 modem-mode guide and our breakdown of the Virgin Media Hub 5 vs Hub 5x differences.
Sky, BT and EE: no modem mode, so it is bridge-behind-the-hub or go to the ONT
None of the three has a true modem mode, so the playbook is different.
Sky hubs cannot be put into bridge or modem mode at all, because Sky authenticates with MER (MAC Encapsulation Routing over IPoE) plus CHAP and DHCP option 61. The everyday fix is to disable both the Sky hub's 2.4GHz and 5GHz WiFi and run your own router behind it, or drop your router into AP mode. On full-fibre FTTP you can connect to the Openreach ONT, though Sky's IPoE/MER authentication (DHCP option 61 plus a recognised WAN MAC) makes a self-configured own-router setup awkward without the right details. We cover the workaround in the Sky bridge mode guide.
BT Smart Hub 2 has no modem mode. On full fibre the clean route is to plug a PPPoE-capable router straight into the Openreach ONT using BT's generic credentials. The big caveat is BT Digital Voice: it forces the Smart Hub 2 to stay as the first device on the ONT, so an own-router setup gets more constrained. The detail lives in our recommended BT Smart Hub 2 replacement guide.
EE tells the same story. The EE Smart Hub has no true modem mode, so you either disable its WiFi and DHCP and let your router work behind it, or on FTTP go direct to the ONT over PPPoE. EE Digital Home Phone forces you to keep the EE or BT hub in the chain. Walk it through with our guide on how to use any router with EE broadband.
The unifying 2026 insight is simple. On full fibre, the hub's missing modem mode matters far less, because the ONT is a separate box and a capable router can usually talk to it directly. On cable or older copper you are stuck working around the hub. For the full-fibre route, see how to connect your own router to an Openreach ONT.
What you actually gain, and the honest limits
The gains are real. You get dramatically better WiFi range and stability from a proper antenna array instead of a locked hub, genuine control (guest networks, custom QoS, a VPN client or server, parental controls, your own DNS), painless mesh expansion later, and a clean NAT for gaming and hosting.
The limits deserve equal billing. There is no line-speed increase. You may lose ISP-tied extras like Virgin WiFi calling, and provider phone services such as BT Digital Voice and EE Digital Home Phone often force the hub to stay in the chain. Support gets murkier too, because the ISP only troubleshoots its own kit. And on hubs without modem mode you are accepting either double NAT or the AP-mode feature limits.
One habit saves a lot of false alarms: reboot order. After a power cut, bring the modem or hub up first, give it a couple of minutes, then power the router. The wrong order is the number-one "my internet is broken" panic.
If you are escaping the hub for control, buy a router with the right WAN. For Virgin's gigabit tiers and any full-fibre ONT route, a true 2.5G WAN matters.
Which router to buy when you are escaping the hub
The lead pick is the ASUS RT-AX86U. It has a genuine 2.5G WAN port (matching Virgin's Hub 5 and 1Gbps-plus full-fibre tiers), strong WiFi 6 range, and AiMesh so you can expand later. It is the natural pairing for modem mode or a direct-to-ONT PPPoE setup.

For the faster CPU and the same true 2.5G WAN, the premium step-up is the ASUS RT-AX86U Pro. For a sub-gigabit package where 2.5G is not needed, the TP-Link Archer AX73 is a strong WiFi 6 router for a normal house at a fraction of the price.
When coverage is the real problem, or your hub simply will not bridge (the Hub 5x, or Sky and EE behind the hub), run a mesh as access points (eero calls this bridge mode; TP-Link Deco calls it Access Point mode). For the simplest setup, the eero Pro 6E is hard to beat.

For value across more floors, the TP-Link Deco X60 is excellent, and for smaller homes on a budget the TP-Link Deco X20 does the job.

If the real issue is dead zones rather than the router itself, our WiFi extender vs mesh guide will sort it.
Quick start: figure out your route in two minutes
- Identify your tech. Cable (Virgin coax), full fibre / FTTP (a separate ONT box on the wall), or copper FTTC. This decides everything.
- Check for modem mode. Virgin, via the Connect app: likely yes on the Hub 5, likely no on the Hub 5x. Sky, BT and EE: assume no.
- Pick the route. Virgin Hub 5 means modem mode. Full-fibre BT, EE or Sky means consider the ONT (mind the phone-service caveats). Everything else means disable the hub WiFi and run AP mode to avoid double NAT.
- Match the router to the route, then check our router lights guide if anything looks off after the swap, and our reset guide for every UK ISP if you need a clean restart.
