Home WiFi & Network Installation

Reliable WiFi in every room and a home network built to support streaming, smart home systems and working from home.

WiFi that works everywhere in the house

Most WiFi problems come from relying on a single router to cover a whole house. Thick walls, extensions, garden rooms and a growing number of connected devices all make it worse.

We design and install home networks with properly positioned wireless access points and wired connections where they matter, so that streaming, video calls and smart home systems work reliably in every room.

What we install

Whole-home WiFi using ceiling or wall-mounted access points
Wired data points for TVs, offices and equipment that need a solid connection
Structured cabling during new builds and renovations
Network equipment racks that keep everything tidy and accessible
Coverage for gardens, garages and outbuildings
Secure network setup to protect your devices and data

How it works

Consultation. We look at the property, where coverage is poor and what you use the network for.
Design. We plan access point positions and cabling routes.
Installation. Cabling, access points and network equipment are installed and configured.
Testing. We check coverage and performance around the property before handover.

A solid network is the foundation of every smart home system we install. For business premises, see data cabling and business WiFi. To improve your WiFi, book a free consultation.

Who home networking is for

Larger and older homes

Thick walls, long layouts and extensions are the usual causes of poor WiFi. Properly placed access points give even coverage throughout.

People working from home

Video calls and cloud software need a stable connection. A wired point at the desk and strong WiFi in the office make a real difference.

New builds and smart homes

Every connected system in the house depends on the network, so we design it at the start alongside the other cabling.

What makes home WiFi reliable

Access points, not extenders

Plug-in extenders repeat a weak signal. Ceiling or wall-mounted access points, each cabled back to the router, deliver a strong signal exactly where it is needed.

Wired where it matters

TVs, desktop computers, games consoles and equipment racks work best on a cable, which also frees up WiFi for phones, tablets and laptops.

Cable during building work

Data cable is inexpensive to install while walls and ceilings are open, and much more disruptive to add afterwards.

Security and guests

We set the network up securely and can provide a separate guest network, so visitors can get online without access to your own devices.

What affects the cost?

Every project is different, so we quote each one individually after a free consultation. The main things that affect the cost of home wifi and network installation are:

The size and construction of the property
The number of access points needed for full coverage
How easy it is to run cabling
The number of wired data points
Coverage for gardens, garages and outbuildings

We are happy to design to a budget and to phase a project so that it can be completed in stages. Book a free consultation to get started.

I can’t recommend Smart System AV highly enough for sorting our office networking and installing a new rack. It’s clear Joe really cares about his work, and that shows in the quality of the execution. Many thanks!

 Trustindex verifies that the original source of the review is Google. We have been very privileged to have Joe work in our new build smart home recently. Joe treated our home with respect, listened to our wants and needs and made sure that we had a system that worked for us from mood lighting, sound systems, automated blinds and curtains, alarm system and CCTV. We are very happy with Joe and his workmanship. Thank you Joe for all you have done. Top notch service

Home WiFi & Networking FAQs

Why is my WiFi poor in some rooms?

A single router often cannot reach the whole house, especially through thick walls or into extensions. Additional access points connected by cable give consistent coverage.

Is a wired network better than mesh WiFi?

Access points connected by cable are generally faster and more reliable than wireless mesh systems, because each one has a dedicated connection back to the network.

Can you extend WiFi to a garden room or outbuilding?

Yes. We can extend the network to gardens, garages and outbuildings.

Do I need a good network for a smart home?

Yes. Smart home, streaming and security systems all depend on a reliable network, which is why we design the network as part of every project.

Do I need to change my broadband provider?

No. We work with your existing broadband connection and improve how it is distributed around the house.

Will better WiFi make my internet faster?

It will not increase the speed coming into the house, but it will make sure the speed you are paying for reaches every room.

Can I have a separate network for guests?

Yes. A guest network lets visitors get online without giving them access to your own devices.
