How many LAN ports should a Wi-Fi router have in 2026: A complete guide to choosing one

Choosing Wi-Fi router, many users pay attention to data transfer speed, support of standards Wi-Fi 6/6E or coverage radius, but they completely forget about such a critical parameter as number of LAN portsAfter all, the number of physical outputs determines how many devices you can connect via cable—and this is critical for connection stability. Smart TV, game consoles, NAS servers or IP cameras. A mistake in choosing will result in the need to purchase additional ones. switches, adapters or put up with lags on the wireless network.

In this article we will discuss:

• 🔌 How many ports are needed? for different scenarios (apartment, office, gaming room).
• 📊 Comparison of routers with 1, 2, 4, 6 and 8 LAN outputs - the pros and cons of each option.
• ⚡ How to increase the number of ports, if they are not enough (without losing speed).
• ⚠️ Typical mistakes when connecting devices to a router and how to avoid them.

Spoiler: Even if you only have 2-3 devices, a router with 4 LAN ports may prove insufficient after a year or two—and here's why.

1. What is a LAN port in a router and why is it needed?

LAN port (from English. Local Area Network) is a connector RJ-45 on the back panel of the router, designed to connect devices via twisted pair (cable Ethernet). Unlike a wireless connection, a wired connection provides:

• 📶 Minimal delays (ping up to 1 ms versus 10-50 ms over Wi-Fi) — critical for online gaming and streaming.
• 🔒 Greater stability: no interference from neighbors, microwaves or thick walls.
• 🛡️ Increased security: It is more difficult to intercept data over a cable than over the air.
• 🚀 Maximum speed: up to 10 Gbps (at Wi-Fi 6 — up to 2.4 Gbps under ideal conditions).

However, not all ports are created equal. Modern routers are equipped with:

• 🔹 100 Mbps - an outdated standard, found in budget models (for example, TP-Link TL-WR840N).
• 🔹 1 Gbps — the most common option (supported ASUS RT-AX55, Keenetic Hero).
• 🔹 2.5/5/10 Gbps — premium models for professionals (Netgear Nighthawk RAXE500, MikroTik CCR2004).

⚠️ Attention: If your router has a port WAN/LAN (usually highlighted in blue), it can be reassigned in mode LAN Through the settings, this will add +1 output. However, the speed on it will be limited by the WAN port's capabilities (often 1 Gbps, even in expensive models).

2. How many LAN ports are needed for different tasks: selection table

The number of ports required depends on the number of devices you plan to connect. via cableIt's important to consider not only current needs but also potential future network expansion. Below are recommendations for typical scenarios:

Please note: the table indicates recommended The number of ports with a reserve. For example, if you currently have 3 devices, but you plan to buy more NAS or a second console, get a router with 6 ports - it's cheaper than buying one later switch.

3. Routers with 1-2 LAN ports: who are they suitable for?

Models with 1-2 ports - this is usually:

• 📱 Mobile routers (TP-Link M7350, Huawei E5788) - for travel or backup Internet.
• 🏠 Budget home routers (Tenda AC10, Mercusys MR70X) — up to 3,000 ₽.
• 🌐 Modem routers from providers (for example, Rostelecom RTK-010).

Advantages:

• ✅ Compact size.
• ✅ Low price (from 1,500 ₽).
• ✅ Enough for minimalist tasks: laptop + smartphone via Wi-Fi.

Flaws:

• ❌ Unable to connect TV + console simultaneously.
• ❌ When connecting NAS or the camera will have to be sacrificed to another device.
• ❌ Often limited by speed 100 Mbps at the ports.

⚠️ Attention: If your provider provides IPTV, one of the two ports can be occupied by television (for example, port LAN4 in routers Keenetic). In fact, for your devices there will be only 1 free exit.

Who is it suitable for:

• 🏡 For students in the dormitory (laptop + smartphone).
• 🚗 For summer residents (Internet distribution to 1-2 devices).
• 📡 For those who use a router as repeater (signal repeater).

Is it possible to increase the number of ports on a router with 1-2 outputs?

Yes, but with some reservations:

1. Connect USB hub with Ethernet (For example, TP-Link UE300) — speed is limited to USB 2.0/3.0 (up to 1 Gbps).

2. Use Powerline adapters (data transmission over electrical wiring) - speed up to 600 Mbit/s, but depends on the quality of the network.

3. Buy unmanaged switch (from 800 ₽) is the best option, but will require additional space and power.

4. Routers with 4 LAN ports: the gold standard for home use

Most modern mid-range routers (ASUS RT-AX56U, Xiaomi AX3000, Zyxel Keenetic Hero) are equipped with exactly 4 portsThis is the optimal solution for:

• 🏠 Apartment or small house (3-4 people).
• 🎮 Gamers who have 1 PC + console.
• 📺 Users Smart TV And 4K streaming.

Advantages:

• ✅ Enough for basic set: TV, set-top box, computer, NAS.
• ✅ Price/quality: models from 4,000 to 10,000 ₽.
• ✅ Support 1 Gbps on all ports (in most cases).

Typical connection diagram for a family of 3:

1. LAN1 → Smart TV (Samsung QLED).
2. LAN2 → Game console (PS5).
3. LAN3 → Work laptop (MacBook Pro).
4. LAN4 → IP camera or NAS (Synology DS220+).

⚠️ Attention: If you have dual-band router (2.4 + 5 GHz), and there are more than 4 devices, you will have to connect some of them via Wi-Fi. In this case, make sure the router supports MU-MIMO (simultaneous work with several clients without speed drops).

Examples of popular 4-port models:

✔ Port speed (must be at least 1 Gbps)

✔ Availability of a 2.5 Gbps port (for future devices)

✔ VLAN support (if IPTV is needed)

✔ Number of USB ports (for printer or 4G modem)

5. Routers with 6-8 LAN ports: for offices and advanced users

If you need to connect 5 or more devices via cable, take a closer look at routers with 6-8 portsSuch models are less common and usually refer to:

• 🖥️ Gaming routers (ASUS RT-AX88U, Netgear Nighthawk RAX120).
• 🏢 Office solutions (MikroTik hEX S, Ubiquiti UniFi Dream Machine).
• 🛠️ For advanced flashable routers (GL.iNet Flint 2 with OpenWRT).

Advantages:

• ✅ Reserve for the future: you can connect a server, several cameras, smart home.
• ✅ High performance: dual-core processors, 512 MB RAM.
• ✅ Additional functions: VLAN, QoS, Dual WAN.

Flaws:

• ❌ Price from 15,000 ₽ (exception - MikroTik from 8,000 ₽).
• ❌ Large dimensions and noisy coolers (in some models).
• ❌ Difficulty of setup for beginners.

Who is it suitable for:

• 🎮 For streamers and e-sportsmen (connecting a PC, capture card, console, microphone).
• 🏢 For small offices (up to 15 employees).
• 🏠 For smart home owners (controllers, cameras, panels, servers).

Configuration example for a gamer:

LAN1 → Main PC (RTX 4090)
LAN2 → Streaming PC (Ryzen 9)
LAN3 → Xbox Series X
LAN4 → VR headset (Meta Quest Pro in Link mode)
LAN5 → NAS (for stream recording)
LAN6 → IP camera (for streaming)
LAN7 → Switch (for additional devices)
LAN8 → Reserve

⚠️ Attention: In routers with 8 ports, one of them is often dedicated to WAN (Internet from your provider). Check the specifications to see how many ports can be used. LANFor example, ASUS RT-AX88U out of 8 ports 1 — WAN, and 1 — 2.5G LAN, the remaining 6 are standard 1G LAN.

6. What to do if you don't have enough ports: 3 ways to expand your network

If your router can't handle the number of devices, don't rush to replace it. There are several ways to add additional ports:

Method 1: Connect an unmanaged switch

The easiest and cheapest solution is to buy Ethernet switch (from 800 ₽). It connects to one of the router's ports and adds 4-8 additional outputs.

• ✅ Pros: low price, easy setup (plug-and-play).
• ❌ Cons: all devices will be on the same network, no traffic management.

Examples of models:

• 🔹 TP-Link TL-SG105 (5 ports, 1 Gbps) — ~1,200 ₽.
• 🔹 Netgear GS308 (8 ports, 1 Gbps) — ~2,500 ₽.

Method 2: Use a managed switch

If needed additional functions (VLAN, QoS, traffic monitoring), get a managed switch (from 5,000 ₽). It allows you to:

• 🔧 Divide the network into segments (for example, separate IP cameras from the main devices).
• 📊 Prioritize traffic (for example, give maximum speed to a gaming PC).

Examples:

• 🔹 Zyxel GS1900-8 (8 ports, 1 Gbps) — ~6,000 ₽.
• 🔹 MikroTik CSS326-24G-2S+RM (24 ports, 1 Gbps + 2 SFP) — ~15,000 ₽.

Method 3: Powerline adapters

If it is difficult to lay cables, use Powerline — data transmission over electrical wiring. Speed ​​up to 1,200 Mbps (actually ~300-600 Mbps).

• ✅ Pros: no need to pull cables, just plug it into the socket.
• ❌ Cons: speed depends on the quality of the wiring, there may be interference.

Examples:

• 🔹 TP-Link AV1000 (set of 2 adapters) — ~3,500 ₽.
• 🔹 Devolo Magic 2 Wi-Fi (with Wi-Fi support) - ~10,000 ₽.

7. Common mistakes when connecting devices to LAN ports

Even if you have enough ports, an incorrect connection can lead to speed drops, connection breaks or IP conflictsLet's look at the most common mistakes:

Mistake 1: Using low-quality cables

If you connect the device with a cable Cat.5e (maximum 1 Gbps) to the port 2.5 Gbps, the speed will drop to 1 Gbps. For full functionality, the following cables are required:

• 🔹 Cat.6 — up to 10 Gbit/s at a distance of up to 55 m.
• 🔹 Cat.6a — up to 10 Gbit/s at a distance of up to 100 m.

Error 2: Connecting to a WAN port instead of a LAN port

If you accidentally inserted the cable into WAN port (usually highlighted in color), the device will not be able to access the local network. Symptoms:

• 🔴 No access to other devices on the network (for example, to NAS).
• 🔴 The Internet works, but local resources don't.

Error 3: Single port overload

If too many devices (for example, 10 cameras) are connected to one router port via a switch, the following may occur:

• 🐢 Speed ​​drop due to limitations of the router's processor.
• 🔄 Packet loss (packet loss) - critical for online games.

How to check if a port is overloaded?

Open your router's web interface (usually 192.168.1.1) and find the section Statistics or Traffic monitoringIf the port load is constantly close to 100%, it needs to be unloaded (by moving some devices to another port or switch).

Error 4: Incorrect VLAN configuration

If your provider uses VLAN For IPTV or telephony, but you haven't configured it in the router, some ports may not work. For example, in Keenetic need to:

1. Log in Internet → Connection.
2. Specify ID VLAN (check with your provider).
3. Bind the VLAN to the desired port (usually LAN4).

⚠️ Attention: Settings VLAN, QoS and traffic prioritization may vary depending on the router firmware. Some providers (for example, Beeline or MTS) block access to these settings in "branded" routers. In this case, you will have to use your router in "proprietary" mode. Bridge or buy a model with support Double NAT.

8. Frequently Asked Questions (FAQ)

❓ Can the WAN port be used as a LAN?

Yes, in most routers WAN port can be reassigned to LAN via the web interface. For example, in ASUS this is done in the section Local Area Network → Router, and in Keenetic - V System → Port SwitchingHowever, the speed on it may be limited (for example, 1 Gbps instead of 2.5 Gbps on ports).

❓ How many devices can be connected to one LAN port via a switch?

Technically - up to 254 (protocol limitation Ethernet). However, in practice, everything comes down to:

• 🔧 Router performance: budget models "suffocate" with 10-15 devices.
• 📶 Port speed: if the port is 1 Gbps, and 5 devices are connected to it via a switch, each will get ~200 Mbps.
• 🛠️ Switch type: Unmanaged switches cannot balance the load.

Optimally, no more than 4-5 active devices per router port.

❓ Does the number of connected devices affect Wi-Fi speed?

No, LAN ports and Wi-Fi They operate independently—the number of wired devices does not affect the speed of wireless ones. However:

• 🔹 If the router is weak (for example, TP-Link WR841N), it may not be able to handle a large load overall.
• 🔹 If devices are actively using the network (for example, torrents on a PC + streaming on TV), this may occur competition for the channel (even via cable).

Solution: enable QoS in the router settings and set priorities.

❓ Which router should I choose for a smart home with 10+ devices?

The following are critical for a smart home:

• 🔹 6-8 LAN ports (for controllers, cameras, servers).
• 🔹 VLAN support (for insulation IoT-devices).
• 🔹 Stable firmware (better OpenWRT or KeeneticOS).

Recommended models:

• 🔹 Keenetic Ultra II (6 ports, 2.5 Gbps, support HomeKit).
• 🔹 Ubiquiti UniFi Dream Machine Pro (8 ports, built-in smart home controller).
• 🔹 MikroTik hEX S (5 ports, flexible configuration, price ~8,000 ₽).

❓ Is it possible to connect a router to a router to increase the number of ports?

Yes, but it requires proper configuration. There are two options:

1. Bridge mode (Bridge):
• 🔧 The second router acts as an "extension" of the first.
• 🔧 All devices will be on the same network.
• 🔧 Setting: Disable DHCP on the second router and connect it through LAN-to-LAN.

Router mode (Router):

• 🔧 The second router creates a separate subnet.
• 🔧 Can be useful for isolating devices (eg. IoT in a separate network).
• 🔧 Setup: Connect the cable from LAN first router to WAN second.

The downside of this solution is double routing (Double NAT) may cause problems with UPnP (for example, in online games).
