5G Hub vs 4G router

Which Three router do you actually need?

Three ships two very different routers depending on the plan. The 5G Hub is the flagship; the 4G unit is a fallback. Picking the right one matters more than the monthly price.

Recommended in 5G areas

Three 5G Hub (ZyXEL)

Three’s flagship router. Connects on 5G where available and falls back to 4G transparently. Wi-Fi 6 dual-band, two gigabit ethernet ports, external antenna sockets if you want to boost signal further.

  • Average ~150 Mbps download, up to 400 Mbps in strong 5G areas.
  • Wi-Fi 6 dual-band, around 30 connected devices supported.
  • External antenna ports for marginal-signal addresses.
  • Falls back to 4G automatically, no settings to change.

Only outside 5G coverage

Three 4G router (ZTE)

A more basic router for homes outside 5G areas. Single-band Wi-Fi, 4G only, one ethernet port. Fine for typical streaming, video calls and remote work, but you will not see fibre-like speeds.

  • Average 20 to 50 Mbps download, depending on 4G signal.
  • Basic Wi-Fi, ~10 connected devices comfortably.
  • Higher latency, occasional drops during peak hours.
  • £6/month cheaper than the 5G Hub plan.

Rule of thumb: if Three’s coverage map shows any 5G at your address, pay the extra few pounds for the 5G Hub. The headroom and Wi-Fi quality are worth it.

Speed guide

Which Three plan matches your use?

Match your household’s real use to the right plan. Heavy users should consider Openreach FTTP if available; lighter users will be happy on Three for less money than most fixed-line ISPs.

Your use case Minimum sensible speed Recommended plan
Browsing, email, social media 15 Mbps 4G Home Broadband
HD streaming on 1 to 2 devices 25 Mbps 4G Home Broadband or 5G Hub
4K streaming on 1 to 2 devices 50 Mbps 5G Hub in good 5G area
Family of 4, multiple devices, video calls 100 Mbps 5G Hub in strong 5G area
Heavy gaming and 4K on 4+ devices 300 Mbps Openreach FTTP recommended
Smart home, content creator, online seller 500 Mbps Openreach FTTP recommended

FAQ

Three home broadband questions and answers

Is Three 5G Home Broadband available at my address?

Three Home Broadband works wherever the Three mobile network reaches, so the test is mobile coverage, not Openreach. Three’s outdoor 4G covers around 99% of the UK population, and 5G now covers most major towns and cities. The fastest way to check is the Three coverage checker. Always verify INDOOR signal where the router will actually live, walls absorb 5G heavily.

What is the difference between the 5G Hub and the 4G router?

The 5G Hub is Three’s flagship router (made by ZyXEL). It uses 5G where available and falls back to 4G if needed, with Wi-Fi 6 dual-band and gigabit ethernet. The 4G router is a more basic ZTE unit, 4G only, for homes outside 5G coverage. If your address has any 5G signal at all, the 5G Hub is worth the extra few pounds a month, you get the headroom and the dual-band Wi-Fi is much better.

How fast is Three 5G Home Broadband in real homes?

Three publishes an average download speed of around 150 Mbps on the 5G Hub, but the real-world number depends on three things: how close you are to a 5G mast, whether your home has thick walls or metal cladding, and how busy the cell is at the time. In strong 5G areas, Selectra has measured 250 to 400 Mbps; in weak 5G areas, 30 to 80 Mbps; in 4G fallback, 20 to 50 Mbps.

How does it compare with Openreach Full Fibre?

For pure speed and reliability, Openreach FTTP wins. A 150 Mbps Full Fibre line is more stable than a 150 Mbps 5G line because fibre does not care about weather, walls or how many neighbours are streaming. But Three 5G Hub wins on three things: no engineer install (router arrives in 1 to 2 working days), no Openreach phone line required (renters love this) and 30-day money-back guarantee if the signal is weak.

Do I need to install anything?

No. The 5G Hub or 4G router arrives pre-configured. You plug it into the mains, wait a couple of minutes for it to find the network, then connect your phone or laptop to the Wi-Fi using the password printed on a sticker on the router. There is no Openreach engineer, no phone-line install, no drilling. If your address has a window with strong signal, place the router there for the best speed.

What happens if my signal is too weak?

Three’s 30-day money-back guarantee covers exactly this case. Order the router, test it for up to 30 days in the rooms you actually use, and if the signal is not good enough, return it and pay nothing. This is the single most useful feature of the offer and the main reason Selectra recommends signing up to it before any 24-month commitment.
