Practical guides to choosing and living with home internet

1. How much speed does a household actually need?

Speed requirements are driven by simultaneous activity rather than by the number of devices. Dozens of idle smart-home devices consume almost nothing; three people on separate video calls while someone streams in 4K is a genuinely demanding pattern.

As a rough frame of reference, a single high-definition stream generally needs a few megabits per second and a 4K stream several times that. Video calls are modest on download but comparatively demanding on upload. Online gaming needs very little bandwidth but is highly sensitive to latency and packet loss, which is why a lower-speed fiber connection often outperforms a higher-speed connection on a congested network.

The practical implication: if your household is upload-heavy — remote work, live streaming, large file uploads, cloud backups — the upload figure deserves more attention than the headline download number.

2. Your WiFi speed is not your plan speed

The plan speed is what arrives at the modem. What reaches a laptop in a back bedroom depends on the router, its placement, the wireless standard it supports, how many walls the signal crosses, and how much interference exists from neighbouring networks.

Common causes of a fast plan feeling slow include a router hidden in a cabinet or basement, an older router unable to deliver the plan's speed over wireless, devices with older WiFi radios, and a single access point trying to cover a large or multi-storey home. Testing over a wired connection at the modem separates a network problem from a WiFi problem in about a minute.

3. Equipment: leased, purchased, or included

Providers handle equipment three different ways. Some include a gateway in the plan price, some lease it as a separate recurring line item, and some allow a customer-owned modem and router. Where purchasing your own is permitted, it can be less expensive over a period of years, but compatibility depends on the specific speed tier and the provider's approved device list.

Two things are worth confirming: whether a monthly equipment charge is included in the price you were quoted, and whether using your own hardware changes eligibility for anything else in the plan.

4. Data allowances and what happens if you pass them

Some plans are genuinely unlimited, some apply a monthly threshold with an overage charge, and some apply a fair-use policy that can slow speeds after a certain volume. Policies vary by provider and, in several cases, by region within the same provider.

Households that stream heavily in 4K, work with large media files, or run frequent cloud backups should ask directly whether a cap applies at their address, what the threshold is, and what the consequence of exceeding it would be.

5. Moving to a new address

Service does not automatically follow you. Your current provider may not serve the new address at all, and where it does, the technology and the available tiers can be different. Promotional pricing tied to your old address does not necessarily transfer.

The sequence that causes the fewest problems: confirm what is serviceable at the new address first, schedule installation there before your move date if possible, and only then arrange disconnection at the old address. Check whether a term agreement at the old address carries a fee if the move is not to a serviceable location.
