How to improve Wi-Fi quality in an apartment: a step-by-step guide with tables and tests

A weak Wi-Fi signal in an apartment is a problem faced by almost one in three users. Whether it's the router that can't reach the bedroom, or the speed that drops in the evening when neighbors are actively using the network, or YouTube videos that constantly freeze. The causes can vary, from improper router placement to outdated firmware or interference from household appliances. But the good news is that in 90% of cases, the problem can be fixed without calling a specialist.

In this article we will look at Practical ways to improve Wi-Fi, which work in 2026: from basic (replacing the router) to advanced (setting up channels and mesh systems). You will learn how diagnose the problem, which settings to change first, and when it's really worth buying new equipment. Finally, there's an FAQ with answers to the most frequently asked questions and a comparison chart of solutions based on price and efficiency.

Important: If you have fiber-optic Internet (for example, from Rostelecom or MTS), but the speed is high via cable and low via Wi-Fi, the problem is definitely with the network settings. If the speed is also low via cable, first check your provider's plan.

📊 How often do you have problems with Wi-Fi?
Constantly
Several times a week
Rarely, but accurately
Never

1. Check the current network status: diagnose before improvement

Before you change anything, you need to understand, where exactly does the signal "sag"?To do this:

  • 📶 Measure the speed on different devices (smartphone, laptop, TV) using Speedtest.net or Yandex InternetometerCompare results for Wi-Fi and cable (if possible).
  • 📊 Check the coverageWalk around your apartment with your phone, looking at the signal strength indicator. Note the "dead zones."
  • 🔍 Channel analysis: use apps like WiFi Analyzer (Android) or NetSpot (Windows/macOS) to see which channels are occupied by neighboring networks.

Typical "symptoms" of poor Wi-Fi:

  • 🐢 Download speed below 10 Mbps with 100+ Mbps plan.
  • 🔄 Constant connection breaks (especially when moving between rooms).
  • 📱 On some devices the internet works fine, on others it slows down.

If the speed via cable is high, but via Wi-Fi it is low, the problem is router or its settingsIf the speed is low in both places, the provider or tariff is to blame.

How to test speed correctly?

For accurate results:

1. Connect your laptop to the router via cable (if possible) and run the test Speedtest.net.

2. Repeat the Wi-Fi test while standing close to the router (1–2 meters).

3. Compare the results. If the difference is more than 50%, the problem is with the wireless network.

4. Run a test in different rooms. If the speed drops by 2 times or more, you need repeaters or a mesh system.

2. Optimal router placement: where to place it and where not to

A router installed in a corner of an apartment or behind furniture loses up to 70% of its signal strength due to physical obstacles. Even if you have TP-Link Archer AX6000 or ASUS RT-AX88U, incorrect placement will negate all the benefits.

Where to place the router:

  • 🏠 Center of the apartment — the ideal option. If your apartment has multiple rooms, place it closer to the room where you use the internet most often.
  • 🪑 At a height of 1–1.5 meters (for example, on a shelf or wall). The signal spreads better when the router is not on the floor.
  • 🚫 Away from:
    • Microwaves, refrigerators, washing machines (create interference).
    • Mirrors, aquariums, metal objects (reflect/absorb the signal).
    • Concrete walls and partitions with reinforcement (weaken the signal by 30–50%).

What should I do if my router is tied to my ISP's cable? Use Ethernet extender (up to 100 meters) or Powerline adapters (transmit internet through electrical wiring). The latter are suitable for apartments with high-quality wiring, but can be slow in older buildings.

The router is located in the center of the apartment or closer to frequently used rooms.

At least 1 meter above the floor

Keep away from household appliances and metal objects

The antennas are directed vertically (if the router is on a table) or at an angle (if on a wall)

3. Router setup: channels, standards, and firmware

Even if the router is perfectly positioned, Incorrect settings can choke speedLet's look at the key parameters:

3.1 Selecting a channel and bandwidth

In city apartment buildings there are canals 2.4 GHz are usually overloaded. Here's what to do:

  • 📡 2.4 GHz: Select the least loaded channel (1, 6 or 11 - they do not overlap). Channel width - 20 MHz (wider - more interference).
  • 🚀 5 GHz: use channels 36–48 or 149–165 (DFC), if your router supports them. Width - 40 MHz or 80 MHz for maximum speed.

How to change the channel:

  1. Go to the router's web interface (usually 192.168.0.1 or 192.168.1.1).
  2. Go to Wi-Fi Settings → General (the name may differ).
  3. Select manual mode and specify the channel.
  4. Save the settings and reboot the router.

3.2. Firmware update

Outdated firmware can cause connection drops and slow speeds. Update it:

  1. Download the latest version from the manufacturer's website (for example, for Keenetickeenetic.com, For ASUSasus.com).
  2. Go to Administration → Software Update.
  3. Download the file and wait for it to reboot (do not turn off the power!).

3.3. Incorporation of modern standards

Make sure that the following are enabled in your router settings:

  • 802.11ac (Wi-Fi 5) or 802.11ax (Wi-Fi 6) for 5 GHz.
  • WPA3 instead of WPA2 (if supported by devices).
  • Beamforming (directional signal transmission) and MU-MIMO (simultaneous work with several devices).

4. Eliminate interference: What's blocking your Wi-Fi?

Wi-Fi signals operate on the same frequencies as many household appliances. Here are the main sources of interference and how to combat them:

Source of interference How does it affect Wi-Fi? Solution
Microwave ovens They operate at 2.4 GHz and create strong interference. Use 5 GHz or move the router further away
Cordless phones (DECT) They occupy 2.4 GHz channels Switch your phone to a different standard or use 5 GHz for Wi-Fi
Neighboring Wi-Fi networks They overload the channels, especially in apartment buildings Select a free channel (see section 3.1)
Bluetooth devices May interfere with 2.4 GHz Disable unnecessary Bluetooth devices or use 5 GHz
Mirrors, aquariums, metal furniture Reflect or absorb the signal Move the router or change the direction of the antennas

If you have dual-band router, separate the networks: for example, MyWiFi_2G And MyWiFi_5GConnect devices that support this standard (smartphones, laptops, TVs) to the 5 GHz band, and smart bulbs, sensors, and older gadgets to the 2.4 GHz band.

How to check which devices are overloading the network?

In the router's web interface, find the section Wireless Mode → Client List or DHCP clientsYou'll see which devices are connected and how much traffic they're consuming. If a device is using too much bandwidth (for example, a torrent on a PC), limit its speed in the settings. Qos or Bandwidth control.

5. Signal amplification: repeaters, mesh systems and antennas

If changing the router settings and reinstalling them doesn't help, it's time to think about hardware solutionsHere's what you can do:

5.1. Wi-Fi repeaters

Repeater captures the router's signal and retransmits it, increasing coverage area. Suitable for apartments up to 100 m².

  • Pros: inexpensive solution (from 1,500 ₽), easy setup.
  • Cons: the speed drops by 2 times (the repeater “shares” the channel with the router), it can create a separate network.

How to choose: take a repeater from the same manufacturer as the router (for example, TP-Link RE605X for routers TP-Link). Setup takes 5 minutes via WPS or web interface.

5.2. Mesh systems

Mesh system (for example, Google Nest WiFi, ASUS ZenWiFi) consists of several nodes, which automatically switch devices between each other, providing stable coverage.

  • Pros: Seamless roaming (no interruptions when moving), high speed, easy to control.
  • Cons: expensive (from 10,000 ₽ for a set of 2-3 units).

Ideal for large apartments (100+ m²) or multi-storey houses.

5.3. Replacing antennas

If your router removable antennas, they can be replaced with more powerful ones. For example, antennas with amplification 5–9 dBi (For example, TP-Link TL-ANT2408CL>) will increase the coverage radius by 20–30%.

⚠️ Attention: too powerful antennas (more 9 dBi) can degrade the signal near the router due to its narrow beam angle. Optimally, 6–7 dBi for the apartment.

5.4. Powerline adapters

If Wi-Fi doesn't go through walls and you can't run a cable, use Powerline adapters (For example, TP-Link AV1000). They transmit the Internet via electrical wiring, and then distribute it via Wi-Fi or cable.

  • Pros: More stable than repeaters, speed up to 1 Gbps.
  • Cons: Depends on the quality of the wiring, more expensive than repeaters.

6. Optimization for specific devices

Sometimes the problem is not in the router, but in device settings, which connects to Wi-Fi. Let's look at the most common cases:

6.1. Laptops and PCs

  • 🖥️ Update your Wi-Fi adapter driver (through device Manager or the manufacturer's website).
  • 📶 Turn off energy saving for adapter:
    1. Go to Control Panel → Power Options → Change plan settings → Change advanced settings.
    2. Find Wireless Network Adapter Settings → Power Saving Mode and install Maximum performance.
  • 🔧 Check your network settings:
    netsh wlan show settings

    Make sure the mode is enabled 802.11n/ac/ax.

  • 6.2. Smartphones and tablets

    • 📱 Forget the network and reconnect: Settings → Wi-Fi → [Your network] → Forget.
    • 🔄 Disable automatic connection to weak networks (in Wi-Fi settings).
    • 📴 Check the power saving mode: some phones (eg Xiaomi) limit Wi-Fi in power saving mode.

    6.3. Smart TV and set-top boxes

    • 📺 Connect via cable, if possible (especially for 4K content).
    • 🔌 Update the firmware TV or set-top boxes (Android TV, LG webOS, Samsung Tizen).
    • 🎮 For game consoles (PS5, Xbox Series X) use 5 GHz or cable - Wi-Fi on 2.4 GHz gives a high ping.

    7. When it's time to replace your router: signs and recommendations

    If you've tried everything and your Wi-Fi is still slow, the problem might be outdated routerHere are the signs that it's time to change it:

    • 🕒 The router is more than 5 years old (especially if it only supports 802.11n).
    • 📉 Maximum Wi-Fi speed is below 100 Mbps (even near the router).
    • 🔄 Constant reboots or freezes.
    • 🚫 No support for 5GHz or Wi-Fi 6 (802.11ax).

    Which router to choose in 2026:

    Apartment type Recommended model Price (≈) Peculiarities
    1–2 rooms, up to 60 m² TP-Link Archer AX23 3 500 ₽ Wi-Fi 6.5 GHz, 4 antennas
    3–4 rooms, up to 100 m² ASUS RT-AX55 6 000 ₽ Wi-Fi 6, Mesh mode, good cooling
    A large apartment or house Keenetic Hero 4G + Mesh 15 000 ₽ Wi-Fi 6, Mesh support, 2.5G port
    For gamers and 4K streaming Netgear Nighthawk RAXE500 25 000 ₽ Wi-Fi 6E (6 GHz), 8 streams, low ping

    ⚠️ Attention: If you have a tariff of up to 100 Mbps, there is no point in buying a router with support 2.5G ports or Wi-Fi 6E — they are needed for speeds of 300+ Mbps.

    8. Alternative solutions: if nothing helps

    If you've tried all these methods and your Wi-Fi is still poor, consider drastic measures:

    • 📡 Laying Ethernet cable to problem areas (for example, to the bedroom or study). Cable Cat 6 provides speeds of up to 1 Gbps at 50 meters.
    • 📶 4G/5G router (For example, Huawei B535) - If the wired internet in your home is unstable, a mobile network may be better.
    • 🏢 Changing providers — Sometimes the problem is a bad line or overloaded operator nodes. Before switching, check coverage reviews in your area.

    If you are renting an apartment and can't run cables, try mobile Internet with an unlimited tariff (for example, from Tele2 or MTS). Modern 5G routers (for example, ZTE MC801A) provide speeds of up to 1 Gbps, which is enough for work and streaming.

    FAQ: Answers to Frequently Asked Questions

    Is it possible to boost Wi-Fi signal using foil or cans?

    Theoretically yes: foil or a metal can can send a signal in the desired direction (the "reflector" effect). However, in practice, the gain is minimal (5-10%), and improper installation can actually worsen coverage. It's better to buy an inexpensive repeater or redirect the router's antennas.

    Why does Wi-Fi slow down in the evening but work fine during the day?

    In the evening the load on neighboring networks increases, which creates interference. Solutions:

    • Switch to 5 GHz (there is less interference).
    • Turn on Qos in your router settings to prioritize your devices.
    • Try changing the channel to a less busy one (see section 3.1).
    How can I check if my neighbor is stealing my Wi-Fi?

    Go to your router settings (192.168.0.1 or 192.168.1.1) and look at the list of connected devices (DHCP clients or Wireless Network → Clients). If you see unfamiliar gadgets:

    • Change your Wi-Fi password to a more complex one (at least 12 characters, with numbers and special characters).
    • Enable MAC address filtering (but this is not a panacea - MAC addresses are easy to spoof).
    • Turn it off WPS - This is a vulnerable protocol.
    Should you turn off Wi-Fi at night?

    From the point of view security - Yes: this will reduce the risk of network hacking. From the point of view of health — There's no evidence that Wi-Fi is harmful, but if you're a light sleeper, you can turn it off. From a health perspective savings — modern routers consume little power (5–10 W), so the difference in your electricity bill will be negligible.

    If you disable it, use schedule in the router settings (for example, System Tools → Schedule).

    Can a router be used as a repeater?

    Yes, many routers (for example, ASUS, TP-Link, Keenetic) support the regime Repeater (repeater) or Bridge (bridge). For this:

    1. Go to the settings of the router you want to make a repeater.
    2. Find the section Opening hours or Wireless Mode.
    3. Select Repeater and connect to the main network.
    4. Save the settings.

    ⚠️ Attention: In repeater mode, the router will work slower than in main mode (speed will drop by 30–50%).
