Who needs to check connectivity first?

People moving home

If you are choosing a connection before or just after a move, check what can be supplied to the new address and when it can be activated before buying equipment for it.

Home workers with uncertain fixed-line service

If calls and cloud-based work depend on the connection, establish whether a fixed service is available and assess any mobile or fixed-wireless alternative at the property before choosing a router.

Households in hard-to-serve locations

Where fixed broadband is limited or unconfirmed, compare provider availability with reception at the property. Satellite also requires a suitable installation position with a clear view of the sky.

What to check before buying

Confirm the connection at the address first, then match the equipment to that service and the way the household will use it.

Concern What to check Who this matters to
Confirming a service route Use Ofcom's checker for the exact address, then ask the provider to confirm orderability, access technology and installation requirements. Ofcom warns that predicted availability can differ from service at a property. If I do not yet know which connection reaches my home, I need to establish that before choosing a router; around 37% of consumers would put confirming the service route first.
Flexible wireless access For mobile or fixed wireless, confirm provider serviceability and test reception where the equipment would sit. Check the intended plan and the exact router's SIM and antenna compatibility. When a fixed connection is delayed or uncertain, I need an alternative I can use at home; around 27% of consumers would make flexible wireless access their primary concern.
Home-working and household use Compare the provider's available service with your simultaneous uses. For an Openreach FTTP connection, check for an Ethernet WAN port to connect to the optical network terminal. If work calls and other household devices will share the connection, I need the service and router setup to suit that use; around 27% of consumers would prioritise this concern.
Satellite installation Check the intended position for sky obstructions before choosing a mount, and establish any property permissions or applicable installation requirements. If other connection routes remain uncertain, I need to know whether a satellite kit can be installed at my property; around 9% of consumers would put that question first.

Purchasing mistakes to avoid

  • Assuming any router will work with the eventual connection

    A DSL modem-router, a router connected to a full-fibre optical network terminal, a SIM router and satellite equipment serve different access routes. An Ofcom coverage prediction does not confirm which service a provider can install at your property.

    Confirm the address, provider and access technology before buying route-specific equipment. Ask how the service connects to the router.

  • Taking outdoor mobile coverage as proof of indoor performance

    Reception at the intended hub position can differ from a coverage prediction or a signal seen outdoors. Placement and network conditions can also affect a mobile or fixed-wireless connection.

    Check the intended network at the address and test likely indoor positions where possible before committing to the equipment and service.

  • Assuming every 5G router uses the same SIM or antenna

    These details depend on the model. Three's documentation identifies a Micro SIM and two TS9 external-antenna connections for its Zyxel NR5103E V2; that does not establish compatibility for another router.

    Match the SIM, plan, supported network bands and any required antenna connectors to the exact router model.

  • Choosing a satellite mount before checking the site

    Starlink says sky obstructions can interrupt its service. An installation position may also raise property-permission or local planning questions.

    Use the provider's obstruction assessment at the intended location, then check the permissions that apply before fitting a permanent mount.

    A position change may also require a different cable route or further mounting work.

Relevant brands and providers

Openreach

Openreach is relevant to the equipment decision at a property with its full-fibre connection; it is not a retail router choice.

  • Openreach instructs users to keep the optical network terminal powered and connect it to the router's WAN port using CAT5e or CAT6 Ethernet.
  • That connection detail does not establish a third-party router's compatibility with a particular internet provider's settings or phone service.

EE

EE offers mobile-broadband hubs as a connection route to consider where a fixed-line service is unavailable or delayed.

  • EE describes its mobile broadband as using a plug-in hub rather than a fixed phone line.
  • Check EE's 4G or 5G coverage at the property and assess the connection indoors; performance depends on local conditions and the chosen service.

Three

Three's mobile-home-broadband equipment is relevant when its service and reception suit the property.

  • Three documents a Micro SIM and two TS9 external-antenna connections for the Zyxel NR5103E V2.
  • Those specifications are model-specific; check the exact hub and service plan before choosing a SIM or antenna.

Starlink

Starlink's satellite equipment is a route to assess at a hard-to-serve property when other connections remain uncertain.

  • Starlink advises using its app to assess the proposed installation position for sky obstructions.
  • A workable position and any necessary permission must be established before fitting the equipment permanently.

Frequently asked questions

Does an Ofcom checker result guarantee broadband at my address?

No. Ofcom says its availability and speed results are predictions, and the service received at a property may differ. Ask the prospective provider to confirm that it can supply the specific address before buying equipment for that connection.

Can I use any router with a full-fibre connection?

No; the router must suit both the installed connection and the provider's requirements. For Openreach FTTP, its optical network terminal connects by CAT5e or CAT6 Ethernet to the router's WAN port. Check provider settings and whether a phone service depends on the supplied hub before replacing it.

What should I check before buying a 4G or 5G home router?

Check usable indoor reception on the intended network, then match the plan and SIM to the exact router. If you need an external antenna, verify that model's connectors and supported network bands rather than relying on another router's specifications.

Do I need permission to install a satellite dish?

You may need permission depending on the property and proposed installation. For England, GOV.UK advises checking planning permission, listed-building consent and landlord or owner permission before installing an antenna. Check the requirements applicable to your property rather than assuming the England guidance covers the rest of the UK.

How can I tell whether satellite equipment is practical at my home?

Assess the intended installation position for a clear view of the sky before choosing a permanent mount. Starlink says obstructions can interrupt its service; also check that the position can be used with the necessary property permissions.
