Network & Wi-Fi support
The network is the part of the office nobody sees.
Until the Wi-Fi drops, the card reader stalls or a video call freezes. This page explains what the boxes in the closet do, why offices outgrow home-style equipment, and what usually causes slow Wi-Fi.

Quick answer
What equipment does a small office network need?
Four things: a modem from the internet provider, a business firewall that controls what comes in and goes out, a switch that connects the wired devices, and wireless access points placed for coverage. A single home-style router tries to be all four at once, which is why offices outgrow it.
The parts, in plain words
Four boxes, four jobs.
Follow the cable from the wall and you will meet them in this order.
Modem
Belongs to your internet provider. It turns the line coming into the building into a connection your equipment can use.
Firewall
The front door. It decides which traffic may come in and go out, keeps your office network separate from the internet, and often provides secure remote access.
Switch
The power strip for network cables. Every wired device plugs into it: desktops, printers, phones, access points. Some switches also power those devices through the cable.
Access points
The Wi-Fi itself. Small radios, usually on the ceiling, wired back to the switch. Several of them working together cover a whole building.
Consumer vs business equipment
Why a home router falls short in an office.
Home-style router
- Built for a handful of devices in a house
- One Wi-Fi radio trying to cover a whole building
- Security updates stop after a few years
- Little or no way to separate guests from office devices
- No alerts when something goes wrong
- No record of what happened
Business network
- Built for dozens of devices in use all day
- Several access points with one network name
- Regular security updates for a longer life
- Separate networks for staff, guests and equipment
- Can be watched remotely, with alerts
- Logs to look at when there is a problem
Two things to get right
Guest Wi-Fi and firewall updates.
Keep guests off the office network
A customer’s phone on the same network as your file server and card readers is a risk you do not need. Guest Wi-Fi should reach the internet and nothing else. The same goes for smart TVs, cameras and personal phones: give them their own network.
Keep the firewall updated
The firewall faces the internet all day, so it is the first thing attackers probe. Manufacturers publish fixes when weaknesses are found. A firewall that has not been updated in years, or is too old to get updates, is an open door with a lock painted on it.
Slow Wi-Fi
The usual causes, in the order we check them.
- 01
Too few access points, or in the wrong place
One unit at the front desk cannot serve the back office through block walls, metal shelving or a walk-in cooler.
- 02
Interference
Neighboring networks on the same channel, and equipment such as microwaves and cordless devices, crowd the older 2.4 GHz band. The 5 GHz band is faster but does not reach as far.
- 03
Old devices
An older laptop or printer can only use older, slower Wi-Fi, no matter how good the access point is.
- 04
Extenders and mesh without wires
A repeater that receives over Wi-Fi and then rebroadcasts spends much of its capacity talking to itself. Access points wired back to the switch do not.
- 05
It is not the Wi-Fi at all
Sometimes the internet connection itself is the limit. Test with a computer on a cable: if that is slow too, the Wi-Fi is not the cause.
Cabling and documentation
The boring parts that save hours.
When the internet is down is the wrong time to hunt for the provider’s account number.
Cabling basics
- Wire anything that stays put: desktops, printers, phones, access points
- Category 6 cable is the usual choice for new office runs
- A single Ethernet run should stay under 100 meters, about 328 feet
- Label both ends of every cable, at the wall and in the closet
- Keep network equipment off the floor, ventilated and on battery backup
What to write down
- Internet provider, account number and support phone
- A simple diagram: what plugs into what
- The firewall, switch and access point models, and when they were bought
- Wi-Fi network names and where the passwords are kept
- Any fixed addresses, such as printers and servers
- Who has the admin sign-ins, and that more than one person can reach them
What it costs
Management is included. New equipment is quoted.
Network and firewall management is part of the plan: updates, monitoring, changes and troubleshooting for the equipment you have. Minimum 5 users. Microsoft 365 licenses billed separately at Microsoft’s price.
- Network & firewall management
- 24/7 monitoring and alerting
- Patch management
- Advanced security monitoring
- Quarterly on-site visits
- Vendor management
Priced in a written proposal before any work starts, with equipment and labor as separate lines.
- A new firewall, switches or access points
- A Wi-Fi coverage redesign
- New cable runs and a tidy network closet
- A network for a new or second location
Questions
Network questions, plainly answered.
Why is the Wi-Fi slow in only part of our building?
Usually distance or materials. Block walls, metal and refrigeration weaken the signal quickly. The fix is normally another access point wired back to the switch, placed where the people are, not a stronger router at the front.
Do we need a firewall if our internet provider gave us a router?
The provider’s box offers basic protection, but it is rarely updated on your schedule, gives you little control and usually cannot separate guest, staff and equipment networks. A business firewall that is kept updated does those jobs properly.
How often should network equipment be replaced?
There is no fixed number of years. The practical test is whether the manufacturer still publishes security updates for it. Once updates stop, plan the replacement, starting with the firewall.
Is guest Wi-Fi safe to offer customers?
Yes, if it is separated so guests reach the internet and nothing inside your office. If guests are on the same network as your computers and card readers, it is not.
Should we use Wi-Fi or cables for office computers?
Cable anything that does not move. Wired connections are faster and steadier, and every device you take off the Wi-Fi leaves more room for the laptops and phones that need it.
Can you work with the equipment we already have?
Yes. We start by looking at what is in place and whether it still gets security updates. We recommend replacing only what you actually need to.
Is network support included in Managed IT?
Network and firewall management is included at $175 per user, per month, with a 5-user minimum. New equipment and cabling projects are quoted separately.
