📶 You upgraded to a faster internet plan, but your Wi-Fi still slows down the moment you walk into the next room. Streaming starts buffering, video calls become unstable, and online games suddenly suffer from higher latency. In many cases, the problem isn't your internet connection—it's your Wi-Fi network. The good news is that a few simple adjustments can often make a noticeable difference, without upgrading your broadband plan or buying expensive new equipment.
A weak Wi-Fi signal remains one of the most common networking issues in homes and apartments. Even with a high-speed fiber connection, poor router placement, thick walls, interference from neighboring networks, and outdated wireless settings can significantly reduce performance by the time the signal reaches the other side of your home.
In this guide, we'll walk through the most effective ways to improve Wi-Fi coverage, increase wireless speeds, and build a more stable home network. We'll start with simple changes that cost nothing and then look at the hardware upgrades that can make a real difference when free solutions aren't enough.
📍 Fix #1: Move Your Router — Yes, It Really Matters
If there's one change that can improve Wi-Fi coverage without costing anything, it's relocating your router. Wireless signals spread outward in all directions, so placing the router inside a cabinet, behind a television, or in the corner of a room prevents much of that signal from reaching the areas where you actually use your devices.
For the best coverage, position the router as close to the center of your home as practical. It should be placed on a shelf or desk rather than on the floor, with plenty of open space around it. Keeping it away from large metal objects and other sources of interference also helps maintain a stronger signal.
- Place the router near the center of your home whenever possible.
- Keep it elevated instead of placing it on the floor.
- Avoid nearby microwaves, cordless phones, baby monitors, and other wireless devices.
- Don't hide the router inside cabinets or enclosed furniture.
- Adjust the antennas according to your home's layout, especially if you have multiple floors.
💡 Example: If your router is installed near your home's entrance but you spend most of your time in a bedroom or home office at the opposite end, simply moving it closer to the middle of the house can noticeably improve coverage throughout the property.
🔄 Fix #2: Restart Your Router Regularly
Routers run continuously, often for weeks or even months without being restarted. Over time, temporary processes, memory usage, and network connections can accumulate, leading to slower performance or occasional connectivity problems.
A simple restart clears temporary data and allows the router to establish fresh network connections. Although it isn't a permanent solution, it often resolves minor performance issues in just a few minutes.
💡 Quick tip: Turn the router off, wait around 30 seconds, and switch it back on. Some users also schedule an automatic weekly restart if their router supports it, helping maintain consistent performance over time.
📡 Fix #3: Choose the Right Wi-Fi Band
Most modern routers broadcast both a 2.4 GHz and a 5 GHz wireless network. Although they provide access to the same internet connection, each frequency is designed for different situations.
...If you're using your laptop or smartphone in the same room as the router, connecting to the 5 GHz network will usually provide higher speeds and lower latency. Devices located farther away, or separated by several walls, often benefit from the greater range of the 2.4 GHz band.
💡 Recommendation: Reserve the 5 GHz band for devices that require maximum performance, such as computers, gaming consoles, streaming devices, and smartphones. Use the 2.4 GHz band for smart home devices or rooms where signal strength is more important than raw speed.
🔧 Fix #4: Keep Your Router's Firmware Up to Date
Your router runs its own operating software, known as firmware. Manufacturers periodically release updates that improve stability, address security vulnerabilities, fix bugs, and occasionally enhance wireless performance.
Unlike smartphones and computers, many routers don't install these updates automatically. Checking for new firmware every few months is a good habit and can help prevent both performance and security issues.
💡 How to check: Open your router's management page—commonly available at 192.168.1.1 or 192.168.0.1—sign in with the administrator credentials, and look for a menu such as Firmware Update, System, or Administration. If an update is available, follow the manufacturer's instructions to install it.
📊 Fix #5: Change Your Wi-Fi Channel to Reduce Interference
If you live in an apartment building, condo, or densely populated neighborhood, your Wi-Fi network is probably competing with dozens of nearby routers at the same time. Every wireless network broadcasts on a specific Wi-Fi channel, and when too many routers use the same one, interference increases — slowing everyone down.
This problem is especially common on the 2.4 GHz band because it has fewer non-overlapping channels available. In most regions, channels 1, 6, and 11 are the best choices because they don’t overlap with one another. If your router is using the same crowded channel as several nearby networks, changing it manually can significantly improve connection quality and stability.
💡 Helpful free app: Apps like Wi-Fi Analyzer (available on Android) can show which channels nearby networks are using. Choose the least crowded channel whenever possible. You can usually change the Wi-Fi channel from the same router settings panel used for firmware updates.
🔌 Fix #6: Use an Ethernet Cable for the Devices That Matter Most
Wi-Fi is convenient, but a physical cable will always be faster and more stable. If you're working from home and need a reliable connection for video calls, or if you have a smart TV that keeps buffering, plugging it directly into the router with an Ethernet cable solves the problem instantly.
You don't have to wire up everything — just the devices where a rock-solid connection matters most. Your work laptop and smart TV are the obvious candidates.
💡 Bonus benefit: Moving your work computer or TV to a wired connection also frees up Wi-Fi bandwidth for everything else — your phones, tablets, and other wireless devices will all feel a bit snappier as a result.
📶 Fix #7: Check How Many Devices Are Connected
Every device connected to your Wi-Fi is sharing the same bandwidth. Phones, tablets, laptops, smart TVs, game consoles, smart speakers, security cameras, robot vacuum cleaners — it adds up fast. A modern home easily has 15–30 connected devices, and if several of them are actively downloading or streaming at the same time, your connection slows down for everyone.
Log into your router's settings page and look for a section called "Connected Devices" or "DHCP Clients." You might be surprised what you find — devices you forgot you even had, or perhaps an unknown device using your network without your knowledge.
⚠️ Heads up: If you see a device on your network that you don't recognize, it might be a neighbor who figured out your Wi-Fi password at some point. You can remove unknown devices from your router's settings and then change your Wi-Fi password to close them out.
📡 Fix #8: Add a Wi-Fi Extender or Mesh System
If you've tried everything above and still have rooms with a weak signal — especially in a larger home, a multi-floor house, or a property with thick stone or concrete walls — it's time to consider some hardware.
You have two main options:
Wi-Fi Extender (Repeater): A relatively inexpensive device (often €30–€60) that picks up your existing signal and rebroadcasts it. It works well for getting signal into one specific dead zone — a garage, a back bedroom, a garden office. The downside is that it creates a second network with a different name, so your phone won't switch to it automatically, and it can cut available speeds roughly in half because it's both receiving and rebroadcasting on the same frequency.
Mesh Wi-Fi System: A more powerful and elegant solution. Instead of one router, you have two or three "nodes" spread around your home, all working as one unified network with the same name. Your devices connect to whichever node gives the best signal, and hand off seamlessly as you move between rooms. Brands like Google Nest WiFi, TP-Link Deco, and Amazon Eero are popular choices. They cost more (typically €150–€400 for a two or three-node kit), but the coverage and reliability improvement is dramatic in larger homes.
💡 Which should you choose? If you just need signal in one extra room — go for an extender. If your whole house feels patchy, or you have two or more floors, a mesh system is worth the investment. It genuinely changes the experience.
🚀 Fix #9: Is Your Router Just Old?
Networking technology has moved fast in the past few years. If your router is more than four or five years old, it may simply not be capable of keeping up with the demands of a modern home — even if your internet plan is perfectly good.
The current standard to look for is Wi-Fi 6 (also written as 802.11ax). Compared to the older Wi-Fi 5 standard, Wi-Fi 6 is not just faster on paper — it's smarter about handling many devices at once, which is exactly what modern homes need. It's especially noticeable when multiple people are online simultaneously.
You don't need to spend a fortune. A solid Wi-Fi 6 router can be found for under €80, and the difference in day-to-day experience in a busy household can be quite noticeable.
