Network setup: what to know

What the job involves, what changes the price, and what to ask a pro.

What network setup is

A technician designs and configures a wired and wireless network, including routers, switches, cabling and security settings for a home or office. You need it when you are setting up a new space, adding devices, or moving to a network that needs to be more reliable and secure.

Signs you need it

  • The network slows down when many devices are connected
  • Devices in different parts of the building cannot reach each other or shared files
  • You need wired connections for a desk, a TV or a server that wireless cannot serve well
  • You are opening a new office, adding staff or moving to a new building
  • The network needs separate areas for work, guests and smart devices

What the pro does

  • Surveys the space and lists the devices and the traffic each area needs
  • Designs the network layout with the router, switches and access points
  • Runs or checks the cabling and terminates it correctly
  • Configures the network settings, the VLANs or guest areas, and the security
  • Tests the speed, the connection and the failover before handing it over

What changes the price

Every job is different, so we do not publish prices. These are the things that move the quote up or down.

  • The size and layout of the space and the number of rooms or floors
  • The amount of cabling needed and how hard it is to run
  • The number and type of switches and access points
  • Whether the network needs separate guest or device areas
  • Whether a firewall or advanced security device is included
  • Whether the work is done on site, in phases or outside working hours

What a written quote should spell out

  • The network diagram and the equipment list
  • Cabling length, termination and any wall plates
  • Configuration of the network and the security settings
  • Testing results and the admin login details delivered in writing
  • Warranty for the work and for the equipment

Questions to ask before you hire

  • Can you show me the network diagram before you install?
  • Which equipment is yours, and which is mine to keep?
  • How do you secure the admin login and the guest network?
  • Will you test the speed and the cable runs?
  • What happens if a switch or router fails after installation?
  • Will you document the network so I can manage it later?

Red flags

  • Installs equipment without a diagram or a written plan
  • Leaves the default admin password in place
  • Uses cabling that is not tested
  • Will not explain the network security settings

What you can do yourself

You can list the devices and rooms that need connections, and measure where cable runs would go. Do not run cable inside walls without knowing where wires and pipes are, and do not work on any power outlet or wall box. Hire a technician for the cable runs, the switches and the security setup.

Licenses and permits

A license is usually not required for network setup, but some areas have rules for cabling inside buildings. Check with your state or local licensing agency, and ask the technician to show proof of training or certifications.

Network setup questions

Do I need a wired network or is Wi-Fi enough?

Wired connections are more stable for fixed devices and large data flows. A technician can tell you which parts of the space need cabling.

How long does a network setup take?

It depends on the size of the space and the amount of cabling. Ask for a schedule in writing before the work starts.

Can I manage the network myself afterward?

Yes, if the technician leaves clear documentation and the admin logins. Ask for both at the handover.
