How to Create a Local Home Network Using a Wi-Fi Router: A Complete Guide

A local area network at home is not just a convenience, but a necessity for the modern user. It allows you to share files between devices without the internet, stream videos from your laptop to Smart TV, print documents from a tablet to a printer, and even play online games with minimal lag. But how do you properly set up such a network via a regular Wi-Fi routerso that all devices can "see" each other and work stably?

Many people mistakenly think that it is enough to simply connect to the same network Wi-FiIn practice, however, problems often arise: computers don't appear in the list of network devices, the printer isn't detected, and files are transferred at dial-up speeds from the 90s. The cause lies in incorrect settings. DHCP, firewall, or shared folder settings. In this article, we'll walk you through step-by-step instructions for creating a local network using routers from popular brands— TP-Link, ASUS, Keenetic And MikroTik, and we will also solve typical problems.

You will learn how to:

• 🔌 Configure your router to correctly distribute local IP addresses
• 🖥️ Connect to the network on Windows, macOS, Linux, Android, and iOS
• 📂 Share folders and printers
• 🛡️ Protect your local network from external threats
• 🔧 Diagnose and troubleshoot problems

1. Preparing the router: basic settings for a local network

Before connecting devices, you need to make sure that the router is properly configured to operate in local network mode. The main parameter is DHCP server, which automatically assigns IP addresses to connected devices. If it's disabled or configured incorrectly, devices won't be able to "see" each other.

Access the router's web interface by entering in the browser's address bar. 192.168.0.1 or 192.168.1.1 (The exact address is indicated on the device sticker). The default login and password are usually admin/admin or admin/passwordFind the section in the menu LAN or Local area network and check:

• 📌 Router IP address (usually 192.168.0.1 or 192.168.1.1)
• 🔄 DHCP server must be enabled (Enabled)
• 📊 Range of distributed addresses (for example, 192.168.0.100 — 192.168.0.199)
• ⏳ IP lease time (recommended) 24 hours or 1440 minutes)

If you have a router that supports Mesh networks (For example, ASUS ZenWiFi or TP-Link Deco), additionally check that all network nodes are in the same IP segmentOtherwise, devices from different access points will not see each other.

⚠️ Attention: On routers MikroTik Configuring DHCP may require creating a separate IP-pool and binding it to the interface bridge-localWithout this, the local network will not work.

2. Setting up devices: Windows, macOS, Android, and iOS

After configuring the router, you need to prepare the devices themselves. Let's start with Windows, as it is the most common system for home PCs. Go to Control Panel → Network and Internet → Network and Sharing Center and select Change advanced sharing options.

Enable the following options:

• 🔹 Network discovery (for all profiles)
• 🔹 File and Printer Sharing
• 🔹 Automatic configuration on network devices
• 🔹 Turn it off password-protected sharing (if the network is trusted)

For macOS open System Preferences → Sharing and activate File sharing, adding folders to the allowed list. On Android And iOS The local network works through special applications (for example, FX File Explorer or Feem), since mobile OSs limit direct work with SMB- protocol.

Are all devices connected to the same Wi-Fi network?

Is DHCP enabled on the router?

Are the sharing settings configured on your PC?

Is the firewall for the local network disabled (temporary solution for testing)?

-->

⚠️ Attention: On Windows 11 after the update KB5028185 (July 2023) Access to network folders may be lost due to changes in the protocol SMBSolution: in Settings → Networks → Advanced settings enable support SMB 1.0 (not recommended for security reasons, but works as a temporary fix).

3. Organizing shared access to folders and printers

To open access to a folder on Windows, right-click on it, select Properties → Access and press ShareIn the drop-down list, select All and set the resolution Reading and writing (or just Reading, if you want to restrict changes). For the printer, go to Control Panel → Devices and Printers, right-click on the printer and select Printer Properties → Access.

On macOS folders are configured via System Preferences → Sharing → File Sharing. Add the folder to the list and specify the rights for users (Read only or Reading and writing). For the printer, enable the option Printer sharing in the same menu.

To connect to a shared folder from another device:

• 🖥️ On Windows: enter in Explorer \\192.168.0.105\folder_name (replace IP with the current one).
• 🍎 On macOS: V Finder click Cmd + K and enter smb://192.168.0.105/folder_name.
• 📱 On Android: use the app Solid Explorer or FX File Explorer, adding network storage via protocol SMB.

4. Device Visibility Issues: Diagnostics and Solutions

A common problem: devices are connected to the same network but don't show up in the network neighborhood. The reasons can vary, from the trivial firewall before the conflict IP addressesLet's start by checking the basic parameters:

1. Make sure all devices are receiving IP addresses from the same range (e.g. 192.168.0.x).
2. Check that working group the same on all PCs (by default) WORKGROUP on Windows).
3. Temporarily disable your firewall and antivirus (for example, Kaspersky or ESET often blocked NetBIOS).
4. Run the command ping 192.168.0.105 V CMDto check the connection between devices.

If ping passes (answers like Reply from 192.168.0.105), but the folders don't open, the problem is in the settings SMB or LLMNRFor Windows 10/11, run in PowerShell as administrator:

Enable-WindowsOptionalFeature -Online -FeatureName"SMB1Protocol" -NoRestart
Set-SmbServerConfiguration -EnableSMB1Protocol $true -Force

On routers ASUS with firmware Asuswrt-Merlin disabling might help AP Isolation (client isolation) on the menu Wireless → ProfessionalThis feature blocks communication between devices on the same network by default.

5. Optimizing the speed and stability of the local network

Local area network via Wi-Fi It will always be slower than a wired connection due to the nature of wireless data transmission. However, speed can be significantly improved by properly configuring your router and devices. Here are the key parameters:

• 📶 Wi-Fi standard: use 802.11ac (Wi-Fi 5) or 802.11ax (Wi-Fi 6) instead of the outdated one 802.11n.
• 🔄 Channel and width: select a free channel (eg. 36 or 149 for 5 GHz) and width 80 MHz (if supported).
• 🔒 Security mode: use WPA3-Personal or WPA2/WPA3-Transition (Not WEP!).
• 📡 MoCA or PowerlineIf your Wi-Fi is unstable, consider adapters. TP-Link AV2000 for transmitting data over electrical wiring.

To test the speed between devices on a local network, use the utility iPerf3Install it on two computers and run the server on one:

iperf3 -s

And on the second one, do:

iperf3 -c 192.168.0.105 -P 10 -t 30

Normal speed for Wi-Fi 5 is 300-800 Mbps, for Wi-Fi 6 - 900-1500 Mbps (under ideal conditions). If the values ​​are lower, check the settings. QoS on the router - local network traffic may be limited.

⚠️ Attention: On routers Keenetic with firmware NDMS v3 enabled by default Bandwidth Management (BWM), which can limit the speed between local devices. Disable it in the menu. Channel width control, if you need maximum performance.

6. Local Network Security: How to Protect Yourself from Data Leaks

By sharing folders and printers, you potentially expose your network to hacking. Here are the minimum security measures you should take:

• 🔐 Disable the guest network, if it's not in use. The guest network is isolated from the main network, but it can become an attack surface.
• 🛡️ Update your router firmware. Vulnerabilities in older versions (for example, CVE-2021-20090 in TP-Link routers) allow hackers to gain access to the local network.
• 🔑 Use complex passwords to access shared folders (even on a home network).
• 📋 Keep a connection logOn routers ASUS And MikroTik enable logging in System log.

For additional protection, please set up VLAN (virtual networks) on the router, if supported. For example, on MikroTik you can create a separate one VLAN For IoT-devices (smart bulbs, cameras) so they don't have access to the main network. Instructions:

/interface vlan add interface=bridge-local name=vlan_iot vlan-id=10
/ip address add address=192.168.10.1/24 interface=vlan_iot

It is also recommended to disable the protocol UPnP in the router settings (Forwarding → UPnP). It simplifies the configuration of devices, but is often used by attackers to carry out attacks from within the network.

7. Alternative ways to create a local network

If setting through Wi-Fi The router is causing problems, consider alternative options:

• 🌐 Cloud solutions: services like Resilio Sync or Syncthing create encrypted tunnels between devices over the Internet, bypassing the router.
• 🔌 Direct connection: connect two PCs with a cable Ethernet (crossover) and assign static IPs (eg 192.168.5.1 And 192.168.5.2).
• 📶 Ad-hoc network: On Windows, you can create a computer-to-computer access point via netsh wlan set hostednetwork mode=allow ssid=MyNetwork key=12345678.
• 🖧 VPN server on the router: on ASUS or Keenetic can be raised OpenVPNso that devices can connect to the local network remotely.

For Android-devices are convenient to use the application LocalSend - it transfers files over a local network without router settings, using multicast (multicast). The speed is lower than SMB, but the reliability is higher.
