Updated September 2026. Equipment names change; the principles here do not. Check current models and your provider’s plans before buying.

For someone who works from home, the network is business equipment. A call that drops during a pitch, an upload that fails at a deadline, a client file on an unprotected connection — these cost money in a way that streaming problems never do. This guide takes you from whatever your provider left in the hallway to a setup you can rely on, in the order that matters.

Start by measuring, not buying

Before spending anything, find out what you actually have:

• Run a speed test from where you work, at the time of day you work — and note the upload figure, not just the download. Video calls and file delivery live on upload.
• Repeat it over a wired connection if you can. If the wired result is much better, your problem is Wi-Fi, not your provider.
• Watch for dropouts rather than speed. Calls fail because the connection stutters, not because it is slow. A long ping test tells you more than a headline speed.

Our guide to testing and fixing a slow connection covers the diagnosis in detail.

Fix things in this order

Wire what matters

The single most effective upgrade for a home office is a cable between your main computer and the router. It removes interference, competing devices and distance from the equation, and it costs the price of a cable. If running one across the house is impractical, a mesh system whose nodes connect over ethernet — or over your existing coaxial or electrical wiring — gets most of the same benefit.

Leave Wi-Fi for the phones, tablets and everything else. Modern routers handle both bands automatically; the older advice about manually splitting them matters mainly for smart home gadgets that only understand the slower band.

Prioritise your own traffic

Most routers can put one device or one type of traffic first. Set your work computer and video calls above everything else, and the family’s streaming stops competing with your client meeting. Look for “QoS”, “traffic prioritisation” or “device priority” in the router’s settings.

Security, because you hold other people’s data

• Change the router’s admin password from the printed default, and store the new one in your password manager.
• Use the current Wi-Fi security standard your devices support, with a long passphrase.
• Turn on automatic firmware updates, or check for them monthly. Router flaws are exploited quickly.
• Disable remote administration and WPS unless you truly need them.
• Put visitors and smart home gadgets on the guest network, away from your work machine.
• Encrypt the laptop itself. A network is no protection against a stolen device.

A VPN is worth having for hotel and café networks, but it is not a substitute for any of the above, and it does not protect a machine that is already compromised. See our cybersecurity essentials guide.

What the router specifications actually mean

• Wi-Fi generation — each generation mainly improves how the router copes with many devices at once, which matters more in a busy household than raw speed.
• Bands — the slower band travels further and through walls; the faster one is for rooms near the router. Some routers add a third band used to link mesh nodes together.
• Gigabit or faster ethernet ports — the reason to buy is the wired desk connection, so check the ports, not just the wireless claims.
• Handling many devices — the feature lists call this MU-MIMO and OFDMA; the practical effect is that phones, cameras and laptops interrupt each other less.
• Update policy — how long the manufacturer promises security updates. This is the specification nobody advertises and the one that decides how long the router is safe to keep.

Ignore the big number on the box. It adds together every band’s theoretical maximum, and no single device will ever see it.

Plan for the day it breaks

• Know your backup connection before you need it — usually your phone’s hotspot. Test it once so you know it works and how much data you have.
• Keep the router on a small battery backup if your power flickers; a brief cut mid-call is avoidable.
• Keep your provider’s fault number saved somewhere that does not need the internet.
• Know which client work can continue offline, so an outage costs an hour rather than a day.

A monthly ten minutes

1. Check for router firmware updates.
2. Look at the list of connected devices and remove anything you don’t recognise.
3. Re-run a speed test at your desk and compare it with your baseline.
4. Restart the router if it has been up for months.

Frequently asked questions

Do I need a business internet plan?

Usually not. What matters is enough upload speed and a stable line. Business plans mainly add a static address and faster fault response — useful if you host something yourself, unnecessary for most freelancers.

Is mesh Wi-Fi better than a single router?

In a larger or awkwardly shaped home, yes — it removes dead zones and hands devices between nodes as you move. In a small flat, a well-placed single router is simpler and often faster.

How much speed do I actually need for video calls?

Less than most people assume; stability matters far more than headline speed. A connection that never stutters at a modest speed beats a fast one that drops packets.

Should I hide my Wi-Fi network name?

No. It makes connecting harder for you and barely inconveniences anyone attacking the network. A long passphrase and current security standard do the real work.
