Most home office spending goes on the visible things. The improvements that make a real difference are duller and cheaper.

The connection, first

A cable to the router beats wi-fi for anyone working from home, and it is the change people resist most.

Video calls are sensitive to brief interruptions in a way that browsing is not. A momentary drop that you would never notice while reading email produces the freeze that makes you repeat yourself.

If a cable is genuinely impossible, get the wi-fi right rather than tolerating it — a mesh unit in the room, or better, one connected by cable. See home wi-fi that covers the whole house.

Also worth knowing: upload speed is what matters for calls, and it is usually much lower than download on consumer connections. If several people in the house are working and streaming simultaneously, upload is where the contention shows.

Audio, second

The most neglected element and the one that most affects how you are perceived.

A laptop microphone sits next to the fan and picks up the whole room. Everything you say arrives with a layer of ambient noise, and other people find you tiring to listen to without knowing why.

A wired headset is a substantial improvement for very little money. A separate microphone on a stand is better again if you are on calls all day and would rather not wear something.

Wired beats wireless here, because wireless audio adds a small delay that makes conversation slightly awkward and occasionally drops out.

The room matters too. Hard surfaces produce echo; a rug, curtains or a bookcase reduce it noticeably.

Lighting, third

Cheaper than a better camera and more effective.

A window behind you turns you into a silhouette. A window in front of you is excellent, free lighting. A lamp positioned to the side and slightly above, pointed at your face rather than at the screen, transforms how a modest camera performs.

Only after fixing lighting is a better camera worth considering, and even then the improvement is smaller than expected.

The screen and the seating

A second screen is the productivity improvement most people notice immediately, particularly for anything involving comparing two things.

Position matters more than specification. The top of the screen at roughly eye level, an arm's length away. A laptop on a desk puts your head down and forward, which is where the neck and shoulder pain comes from.

A laptop stand plus a separate keyboard and mouse costs little and fixes the posture problem entirely.

On seating: an adjustable office chair is worth the money if you sit for six hours a day. A dining chair is not designed for it. If your employer will contribute, ask — many will.

Spend in this order: connection, audio, lighting, screen position, chair. Almost everybody does it backwards.

The things people forget

Backups

If you work for an employer, your files should live in their cloud storage rather than on your local disk, so they are protected and accessible without you thinking about it.

If you work for yourself, an automatic cloud backup running continuously plus an occasional copy to an external drive covers most disasters. See home storage and family backups.

Separating work and personal

Separate user accounts on a shared computer at minimum. Ideally separate machines, because a work machine used by the household for other purposes is a risk to your employer and an awkward conversation waiting to happen.

Security

Router administrative password changed from the default. Automatic updates enabled on everything. Multi-factor authentication on work accounts, and on your personal email — which is the account that can reset all the others. See home network security basics.

Where you sit relative to the household

Not a technical point and often the one that matters most. A door that closes, or at least a position facing away from the through-route, changes the experience of a working day considerably.

What not to spend on

A very high-end camera. Video calls compress heavily. The difference between a decent camera in good light and an expensive one is largely invisible to the other person.

An expensive router, unless you have established the router is the problem.

Large curved monitors, if your work is documents and calls. Two ordinary screens are usually more useful.

Ring lights, in most cases. A lamp you already own, repositioned, does the same job.

The five-minute check

Start a call with yourself and record it. Watch it back.

You will notice the lighting, the angle, the background noise and the audio quality far more clearly than you do live, and it will tell you exactly which of the above to address first.
