Which Router Works With My Broadband?

Yes, with caveats. BT's help article says you can use your own modem or router if it is compatible with the service and can establish a PPPoE session with the username and password BT gives you, but BT's helpdesk does not support third-party routers and its engineers will not connect non-BT equipment. On full fibre the router's Ethernet WAN port plugs into the Openreach ONT. If you have Digital Voice, the phone runs through the Smart Hub, so keep it in place.

Through modem mode. Hub 3, Hub 4 and Hub 5 can be switched to modem mode at 192.168.0.1, which turns the Hub into a cable modem and lets you connect your own router to it; Virgin's page says the phone service keeps working while Intelligent WiFi, Plume pods and the Connect app features stop. The Hub 5x used on Virgin's XGS-PON full fibre does not currently offer modem mode, so Gig2 customers on that hub cannot swap it out.

Not for the WAN port: a gigabit WAN port carries roughly 940 Mbps, which is enough for every 900 Mbps tier from BT, EE, Sky, TalkTalk, Plusnet and Zen. The routers here that only have gigabit ports (the Deco X55, the Deco X10 and the Slate AX) fit these packages; the 2.5 Gbps ports only start to matter on Gig1, 1.6 Gbps, 2 Gbps and 2.5 Gbps lines. The reason to change router on a 900 Mbps line is Wi-Fi coverage, not the line.

A setting on a provider's hub that switches off its router functions (Wi-Fi, DHCP, firewall) and passes the public IP address straight through one Ethernet port to a router of your own. Virgin Media's Hubs use it because there is no separate ONT on a cable line; on Openreach, CityFibre and most altnet full fibre you connect your router directly to the ONT instead, so no modem mode is needed.

PPPoE is the log-in step BT, EE, Plusnet, Vodafone and Zen use on Openreach lines: the router opens a session over the Ethernet link and authenticates with a username and password. EE publishes a generic pair (bthomehub@btbroadband.com with the password BT or blank), Plusnet's is your account name followed by @plusdsl.net, Zen's follows the pattern zen123456@zen, and Vodafone gives you yours on request. TalkTalk, Community Fibre and YouFibre use DHCP with no log-in at all, and Sky and NOW use DHCP with an option 61 identifier instead.

Often not, unless the provider's hub stays in the chain. Digital landlines run over broadband and plug into the provider's hub: BT's Digital Voice needs the Hub powered, EE says Digital Home Phone needs the EE or BT hub as the primary router, and Vodafone says any plan with Digital Voice must use the Vodafone router. The analogue phone network closes at the end of January 2027, so this applies to more homes each month. Virgin Media is the exception, because its hub keeps the phone running in modem mode.

No. Wi-Fi 7 only speeds up devices that support it, and in most homes that is a recent phone and little else. What matters on a fast UK line is the WAN port: a Wi-Fi 6 router with a 2.5 Gbps port will use a 1.6 Gbps line, and a Wi-Fi 7 router with a gigabit port will not. Buy Wi-Fi 7 if you expect to keep the router for five years; buy mesh if the problem is coverage.

Sky and NOW do not use PPPoE in the UK. The router asks for an address by DHCP and has to include an option 61 client identifier, a string in the form username@skydsl|password, which DrayTek's set-up guide documents and which many consumer routers cannot send. ASUS's WAN settings have an option 61 field; TP-Link says option 61 is not supported on any of its routers, though its FAQ also says most Sky lines connect with a plain Dynamic IP WAN type. Neither Sky nor NOW publishes a help page on third-party routers, so check before you buy.
