How to Improve Your Router's Wi-Fi Range: A Step-by-Step Guide for Home and Office

A weak Wi-Fi signal is one of the most common problems faced by home and office network users. Even modern routers with Wi-Fi support Wi-Fi 6 And MU-MIMO Internet access points may distribute the internet ineffectively if their settings aren't optimized for specific conditions. This results in constant connection drops, slow download speeds, and "dead zones" in the apartment where there's no network connection at all.

There are various reasons for poor Wi-Fi performance, ranging from simple interference from neighboring routers to outdated firmware or improper device placement. In this article, we'll look at 10 Proven Ways to Improve Your Router's Wi-Fi Range, which work regardless of the model (TP-Link, ASUS, Keenetic, MikroTik and connection type (cable, ADSL, 4G/5G). All methods have been tested on real devices and do not require the purchase of additional equipment—except in rare cases where a repeater or mesh system is essential.

Important: If the problem with data distribution occurs suddenly (for example, after a thunderstorm or a firmware update), first check the physical condition of the router—a port may be burned out or the antenna damaged. Otherwise, follow the instructions below, starting with the simplest methods.

1. Optimal router placement

The first thing you need to do is properly position the router in the room. Even the most powerful one ASUS RT-AX88U It won't save you if it's in a corner behind a closet or surrounded by concrete walls. Here are the key rules:

• 📍 Center of the apartment/house — the perfect location. The signal is distributed evenly in all directions.
• 🚫 Avoid closed spaces: cabinets, niches, metal surfaces (refrigerator, radiator).
• ⬆️ Height 1–1.5 meters From the floor. On the floor, the signal is dampened by furniture, and under the ceiling, it is rarely used.
• 📶 Stay away from interference: microwaves, cordless telephones, Bluetooth speakers (operate at a frequency of 2.4 GHz).

If your router supports replaceable antennas (For example, TP-Link Archer C6), try rotating them at a 45° angle—this helps disperse the signal horizontally and vertically. For two-story houses, it's best to position the antennas vertically: one facing up, the other facing down.

2. Selecting the correct channel and frequency

Most routers default to automatic channel selection, but this isn't always optimal. In apartment buildings, channels 2.4 GHz (especially 1, 6, 11) are often overloaded, causing interference and speed drops. Here's how to fix it:

1. Check the channel load using utilities:
   • 🖥️ Wi-Fi Analyzer (Android)
   • 🍎 NetSpot (macOS/Windows)
   • 🌐 inSSIDer (professional tool)

How to change the channel in the router settings (using an example) Keenetic):

1. Go to the web interface at 192.168.1.1 (or my.keenetic.net).
2. Go to Wi-Fi → Hotspot.
3. In the section Radio settings select Manual channel selection.
4. Save the changes and reboot the router.

If your router supports dual range (2.4 + 5 GHz), separate the networks: leave 2.4 GHz for older devices (smart bulbs, printers), and use 5 GHz for laptops and smartphones. This will reduce the load on each band.

3. Updating the router firmware

Outdated firmware can not only slow down Wi-Fi distribution but also contain security vulnerabilities. Manufacturers regularly release updates that improve connection stability and add support for new standards (for example, Wi-Fi 6E) and fix bugs.

How to update firmware:

1. Find out the router model (written on the sticker at the bottom).
2. Download the latest firmware from the official website (tp-link.com, asus.com and others).
3. Go to the router's web interface (usually 192.168.0.1 or 192.168.1.1).
4. Find the section System Tools → Software Update (or similar).
5. Upload the downloaded file and wait for the process to complete (do not turn off the router!).

-->

⚠️ Caution: If your router shuts down during a firmware update (for example, due to a power surge), it may brick the router. Always use an uninterruptible power supply (UPS) or a laptop with a fully charged battery.

After updating, reset your router to factory settings (Reset (press and hold the button for 10 seconds) and configure it again. This will help avoid conflicts between old configurations and the new firmware.

4. Setting the transmission power and operating mode

Many routers allow you to adjust the signal transmission power (in mW or dBm). By default, it's often set to medium, but in some cases it can be increased—or, conversely, decreased—to reduce interference.

Where to find power settings:

• TP-Link: Wireless → Wireless Advanced → Transmit Power (select High).
• ASUS: Wireless → Professional → Tx Power Control.
• MikroTik: Wireless → Interfaces → [your network] → Advanced → Tx Power.

Optimal values:

Mode	Power (dBm)	When to use
Low	10–15	For small rooms (up to 30 m²) or if the router is located next to the devices.
Average	17–20	Standard mode for apartments of 50–70 m².
High	23–27	For large homes or offices (may increase disturbance to neighbors).
Maximum	30+	For open spaces (warehouses, hangars) only. In an apartment, it will cause a power surge.

Also check Wi-Fi operating mode (Wireless Mode). If you have a mixed network (old and new devices), select 802.11b/g/n/ac/ax for maximum compatibility. If all devices are modern, leave only 802.11n/ac/ax to increase speed.

5. Optimize security settings

Incorrect security settings can not only weaken the signal but also make the network vulnerable to hacking. Here's what to check:

• 🔒 Encryption type: use only WPA3-PSK (or WPA2-PSK, if WPA3 is not supported). WEP And WPA are outdated and easily hacked.
• 🔑 Complex password: minimum 12 characters with letters, numbers, and special characters. Example: WiFi#2026_K33n3t1c!.
• 📡 Hiding the SSID: disable the option Hide SSIDThis does not improve security, but it does make connecting new devices more difficult.
• 🛡️ Guest network: If you often have guests, create a separate network with limited access to local resources.

How to change the encryption type on Keenetic:

1. Go to Wi-Fi → Hotspot.
2. In the section Security select WPA3-Personal.
3. Set a new password and save the settings.

⚠️ Attention: If after changing the encryption some devices stop connecting (for example, old printers or IP cameras), please return WPA2-PSK or set up a separate network for them.

6. Use of additional equipment

If you've tried all software methods and the signal is still weak, you'll need to consider purchasing additional equipment. Here are the most effective solutions:

• 📶 Wi-Fi repeater: Boosts signal strength in dead zones. Suitable for apartments up to 100 m². Example: TP-Link RE605X (supports Wi-Fi 6).
• 🔄 Mesh system: Multiple access points working as a single network. Ideal for large homes. Examples: ASUS ZenWiFi AX, Google Nest WiFi.
• 📡 Directional antenna: if you need to "break through" the signal through a thick wall or outside. For example, an antenna TP-Link TL-ANT2408CL (8 dBi).
• 🔌 Powerline adapter: transmits internet through electrical wiring. Useful when cable installation is impossible. Example: Devolo Magic 2 WiFi.

How to choose a repeater:

Please check your router before purchasing. bridge mode (WDS) or MeshIf not, the repeater will have to be configured as a separate network, which isn't always convenient (you'll have to reconnect when moving between zones).

7. Diagnostics and troubleshooting

If Wi-Fi speed drops sharply at certain times of day (for example, in the evening), external interference is to blame. There are two types of interference sources:

1. Radio frequency:
   • Neighboring Wi-Fi networks (especially 2.4 GHz).
   • Bluetooth devices (headphones, speakers).
   • Microwave ovens, baby monitors, wireless cameras.
