Short answer
For an office of 10 to 30 people, buy one managed system rather than separate boxes: a business gateway, a PoE switch and ceiling access points from the same platform, managed through one controller.
That single decision is what separates an office network you can maintain from one that becomes a mystery within a year. On a managed system a VLAN created once exists everywhere. On a consumer router plus an unmanaged switch plus range extenders, nothing can be segmented and nothing can be diagnosed.
The core build: Omada ER707-M2 gateway ($99.99), TL-SG3452P 48 port PoE switch ($542.99), two or three EAP650 access points ($89.99 each), and a 12U rack ($89.90). Around $900 to $1,000 before cabling.
Then do the thing that matters most: segment the network with VLANs. Staff, guests, phones and cameras must not share one flat network.

Step 1: Buy a system, not a collection of boxes
This is the decision everything else depends on, and it is the one most small offices get wrong.
The common approach is a consumer router from the internet provider, an unmanaged switch when ports run out, and a couple of range extenders when the WiFi does not reach. Each piece is bought separately to solve one problem.
The result cannot be segmented, cannot be monitored and cannot be diagnosed. Nobody knows what is plugged into what, and every change is a guess.
A managed platform means the gateway, switches and access points are configured from one controller. Create a guest VLAN once and it exists on every port and every access point. Look at one dashboard and see every connected device and where it is plugged in.
The main options for a small office are TP-Link Omada, Ubiquiti UniFi and HPE Instant On. All three work. Omada is used in the build below because it is the cheapest complete platform and needs no subscription.
Pick one and stay in it. Mixing platforms loses the single pane of management that was the reason to buy in.
Step 2: Size the equipment
The gateway
The Omada ER707-M2 at $99.99 handles far more than a 30 person office needs, and that headroom is the point. It supports 500,000 concurrent sessions and over 1,000 clients.
Session count matters more than people expect. Every browser tab, every cloud application, every phone checking email opens connections. Thirty people can easily hold tens of thousands of sessions, which is where a consumer router starts dropping them and everything feels slow for no visible reason.
It has a 2.5 Gigabit WAN port, so a business fibre service above a gigabit is not throttled at the door, plus a second 2.5G WAN/LAN, four gigabit ports and an SFP slot.
VPN capacity is the other reason to buy business hardware: up to 100 site to site IPsec tunnels and 66 OpenVPN connections, which covers remote staff and a second site.
The USB port supports an LTE dongle for failover, so a broadband outage does not stop the office.
The switch
Count your ports honestly: one per desk, one per printer, one per access point, one per camera, one per phone if they are not daisy chained through the desk PC, plus 30 percent spare.
A 30 person office typically lands between 40 and 55 ports, which is a 48 port switch.
The PoE question decides the price. The TL-SG3452P at $542.99 gives 48 PoE+ ports with a 384W budget, powering access points, IP phones and cameras over the same cable that carries their data. No power adapters, no sockets in ceilings.
The SG2452LP at $359.99 saves $180 with no PoE. If you have three access points and nothing else needing power, three PoE injectors at around $20 each is cheaper. Beyond about ten powered devices, the PoE switch wins.
Watch the PoE budget. 384W across 48 ports averages 8W each. Our PoE power budget calculator adds your own devices up against a switch budget. Access points draw 10 to 15W and IP phones 5 to 8W, so a realistic mix fits comfortably. Twelve cameras with heaters would not.
Access points
Do not use a router’s WiFi to cover an office. Ceiling mounted access points are the correct approach and the difference is not subtle.
Plan roughly one access point per 1,500 to 2,000 sq ft of open office, and more where walls are solid. Three EAP650 units at $89.99 each cover most small offices.
Mount them on the ceiling, in the open. An access point in a cupboard or above a suspended ceiling tile loses a large part of its range before it starts.
The EAP650 is WiFi 6 AX3000 with mesh, seamless roaming, WPA3, band steering and load balancing. Seamless roaming is the feature that matters day to day: a staff member walking from a desk to a meeting room stays on the same call rather than reconnecting.
The EAP613 at $69.99 is AX1800 and saves $20 per unit, which is a reasonable trade in lower density areas such as corridors and storage.
Step 3: Segment the network with VLANs
This is the highest value hour of work in the whole project, and it is routinely skipped.
On a flat network, every device can reach every other device. A compromised smart TV, a guest laptop with malware or a camera running old firmware sits on the same network as the accounts computer.
Four VLANs cover most offices:
Staff. Computers and company phones. Full access to internal resources.
Guest. Visitor devices. Internet only, isolated from everything else, on its own WiFi network with a separate password.
Voice. IP phones, prioritised with quality of service so a large file transfer cannot degrade a call.
IoT and cameras. Cameras, sensors, smart devices. No internet access unless a device genuinely needs it, and no access to the staff network.
On a managed platform this is configuration rather than extra hardware. Create the VLANs in the controller, assign switch ports and WiFi networks to them, and set firewall rules between them at the gateway.
Camera segmentation deserves emphasis. IP cameras are among the most frequently compromised devices on business networks, because they run old firmware that is rarely updated. Isolate them.
Step 4: Cable properly
Cable everything that does not move. Desktops, printers, phones, access points, cameras. WiFi is for laptops, phones and tablets. A wired connection is faster, more reliable, and takes load off the wireless.
Cat6 is the right choice in 2026. It handles 1 Gbps easily and 10 Gbps to 55 metres, which covers any office run. Cat6a costs more and is thicker and stiffer to pull; Cat5e is cheap and caps you at gigabit in a building you will be in for a decade. Our Cat6 vs Cat6a vs Cat7 vs Cat8 comparison covers where each one is genuinely worth the money.
Terminate into a patch panel, not directly into the switch. Every wall outlet runs back to a fixed port on the panel, and short patch leads connect panel to switch. That means moving a device is a thirty second job at the rack, and a damaged lead is replaced rather than a wall run being re-terminated.
Label both ends of every cable as you pull it. It takes seconds then and hours later.
Keep runs under 90 metres from panel to outlet, which is the Ethernet limit, with 10 metres allowed for patch leads at each end.
Step 5: Rack it
A rack is not tidiness for its own sake. Equipment stacked on a shelf overheats, gets knocked, and nobody can tell what is connected to what.
The Tecmojo 12U at $89.90 mounts on the floor or a wall and holds 260 lbs floor standing. Twelve units covers a gateway, a 48 port switch, a patch panel, a power distribution unit and a small UPS with room spare.
Two things to add that cost little. A rack mount UPS, so a brief power cut does not drop the internet and corrupt anything. And blanking panels in empty units, which stop hot exhaust air recirculating to the front of the equipment.
Our guide to server racks covers depth, hole types and load ratings in detail.
Step 6: Things to set before you finish
Change every default password, including the switch, the gateway, the access points and any camera. Default credentials are the most common way small business networks are compromised.
Turn on automatic firmware updates, or diary a monthly check. Network equipment security fixes matter and unpatched devices stay vulnerable indefinitely.
Set up quality of service and prioritise voice and video traffic, so a backup upload does not ruin a client call.
Export the configuration from the controller and store it somewhere off the network. Rebuilding a network from memory after a hardware failure is a bad day.
Document it. A one page diagram, a list of what is on which VLAN, and a table of which patch panel port serves which desk. Whoever inherits this network will need it, and that may be you in two years.
The equipment, in detail
Gateway
Omada ER707-M2 Multi-Gigabit VPN Router
A hundred dollars for a gateway that handles more than most small offices will ever ask of it, which is exactly what you want at the front of a network.
Five hundred thousand concurrent sessions and over 1,000 clients. A consumer router typically manages a few thousand sessions, and when it runs out the symptom is not an error but a network that feels slow with no obvious cause.
Ports are flexible: one 2.5G WAN, one 2.5G WAN/LAN, four gigabit WAN/LAN, one gigabit SFP WAN/LAN and a USB 2.0 port. Multiple WAN ports allow load balancing across two internet services, or failover if one drops.
The USB port supports an LTE dongle for backup, which for the price of a data SIM keeps the office online through a broadband outage. For any business that takes orders or calls over the internet, that is cheap insurance.
VPN capacity is generous: 100 site to site IPsec tunnels, 66 OpenVPN, 60 L2TP and 60 PPTP connections. Enough for remote staff and branch offices without a separate appliance.
Omada integration means it is configured from the same controller as the switches and access points, with cloud access for remote management.
Five year warranty with free technical support on weekdays.
It has no WiFi, which is correct for this design, because access points do that job far better than a router in a cupboard.
What works
- 500,000 sessions, far beyond what a consumer router manages
- 2.5G WAN so a fast business fibre service is not throttled
- LTE dongle failover keeps the office online in an outage
- Five year warranty and Omada controller integration
What doesn’t
- No WiFi, so access points are a separate purchase
- Needs a controller to get the full platform benefit
- Gigabit LAN ports rather than multi gig throughout
Buy this as the front door of the office network, with headroom you will not outgrow.
Switch with PoE
TP-Link TL-SG3452P
Forty eight PoE+ ports covers a 30 person office with room to grow, and PoE removes the need for a power socket at every access point and camera.
Each port supplies up to 30W under 802.3at, with a 384W total budget. Do the arithmetic for your own devices: access points at 10 to 15W and IP phones at 5 to 8W leave plenty of margin, while a dozen heated cameras would not.
PoE Auto Recovery is the feature that saves real time. The switch pings each powered device and power cycles its port if it stops responding. An access point frozen in a ceiling void recovers itself instead of needing a ladder and a lunchtime.
L2+ static routing lets traffic between VLANs be routed on the switch rather than sent up to the gateway and back. On a segmented network that keeps internal traffic local and off the gateway.
Four gigabit SFP slots for fibre uplinks, useful for reaching another floor or building.
Security features cover what an office needs: 802.1Q VLANs, IP-MAC-Port binding, ACLs, port security, DoS defence, storm control, DHCP snooping and 802.1X RADIUS authentication.
Omada integration means it appears in the same controller as the gateway and access points. Check the firmware is the SDN version, since non SDN firmware will not join a controller.
It has fans, so it belongs in a rack in a separate room rather than in an open office.
What works
- 48 PoE+ ports remove the need for power at every device
- PoE Auto Recovery reboots a frozen ceiling device by itself
- L2+ routing keeps inter VLAN traffic off the gateway
- Full security set including 802.1X and DHCP snooping
What doesn’t
- 384W averages 8W per port if all 48 are used
- Fans mean it needs a separate room
- $180 more than the equivalent switch without PoE
Buy this when you have ten or more PoE devices. Below that, injectors are cheaper.
Access point
Omada EAP650 WiFi 6 Access Point
Ninety dollars per access point, and three of them cover most small offices far better than any router’s built in WiFi.
Free cloud management with no subscription is the standout. Scan the serial number in the Omada app and the unit is adopted. No hardware controller and no licence, which is where competing platforms often add cost.
WiFi 6 AX3000 with 1024-QAM, boosting dual band speeds to 2,976 Mbps. More relevant than the headline number is how WiFi 6 handles many devices at once, which is the actual office problem: thirty laptops and thirty phones on one access point.
Seamless roaming hands a device between access points without dropping the connection, so a call survives the walk from a desk to a meeting room. It requires an Omada controller, which the cloud option provides free.
Band steering pushes capable devices to 5 GHz, load balancing spreads clients across access points, and airtime fairness stops one slow old device holding up everyone else. That last one matters more than people realise in an office with mixed hardware.
WPA3 support, and the slim design mounts discreetly on a ceiling.
PoE powered, so one cable does data and power. That is why the PoE switch above earns its price.
Mount it in the open. Above a ceiling tile or inside a cupboard, an access point loses much of its range before it starts.
What works
- Free cloud management with no controller hardware or licence
- WiFi 6 handles many simultaneous devices, the real office problem
- Seamless roaming keeps calls alive between rooms
- Airtime fairness stops one old device slowing everyone
What doesn’t
- Roaming and mesh need an Omada controller
- Needs a PoE switch or an injector per unit
- Loses much of its range if mounted out of sight
Buy one per 1,500 to 2,000 sq ft of open office, mounted on the ceiling in the open.
Frequently asked questions
How much does a small office network cost?
For 10 to 30 people, budget around $900 to $1,000 for the core equipment: a gateway at $99.99, a 48 port PoE switch at $542.99, three access points at $89.99 each and a rack at $89.90. Cabling and installation are separate and often cost as much again.
Do I need a business router or is a consumer one enough?
A business gateway, for session capacity rather than speed. Thirty people generate tens of thousands of concurrent sessions, and a consumer router runs out without reporting an error, which shows up as a network that feels slow for no visible reason.
How many WiFi access points does an office need?
Roughly one per 1,500 to 2,000 sq ft of open office, and more where walls are solid or device density is high. Three access points cover most small offices. Mount them on the ceiling in the open, not above tiles or inside cupboards.
What VLANs should an office network have?
Four cover most cases: staff with full internal access, guest with internet only and full isolation, voice with quality of service priority, and IoT and cameras with no access to the staff network. Camera isolation matters most, because cameras run old firmware and are frequently compromised.
Should I use Cat6 or Cat6a cable?
Cat6 for almost every office. It carries 1 Gbps easily and 10 Gbps to 55 metres, which covers any run in a normal building. Cat6a costs more and is thicker and stiffer to pull, and is only worth it for long 10 Gbps backbone runs.
Do I need a patch panel?
Yes, for anything beyond a handful of ports. Wall outlets terminate at the panel and short leads connect panel to switch, so moving a device is a thirty second change at the rack rather than re-terminating a wall run, and a damaged lead is simply replaced.
The verdict
Buy one platform and stay in it. The Omada ER707-M2 at $99.99, the TL-SG3452P at $542.99 and three EAP650 access points at $89.99 each give a 30 person office a network that can be segmented, monitored and handed over, for around $900 plus a $89.90 rack.
If you have fewer than ten powered devices, take the SG2452LP at $359.99 and use injectors, saving $180 and gaining a silent fanless switch.
Then spend the hour that matters most: create four VLANs, isolate the guests and the cameras, change every default password, and write down what is plugged into which patch panel port. That hour is worth more than any hardware upgrade you could make later.
