📶 Why is your Wi-Fi slow?

Before we start improving your network, let's understand why you might be having problems. Wi-Fi is like a radio that broadcasts from your device. When there are obstacles, interference, or incorrect settings, the signal weakens.

The most common reasons:

• 🧱 Walls and furniture blocking the signal
• 📱 Multiple devices connected simultaneously
• 🏘️ Interference from neighbors' Wi-Fi
• 📍 Poor placement of the device
• ⚙️ Incorrect settings
• 🕰️ Old software that needs updating

📍 The Correct Placement of the Router

The location of your device is the most important thing! Think of the signal as light that is emitted in all directions.

1Central Location

Place the device in the center of the house, not in a corner. This way the signal will reach all rooms evenly.

💡 Tip:

If your house is two-story, place the device on the first floor for better coverage on both levels.

2Height from Floor

Place the device at least 1-2 meters above the floor. A shelf or piece of furniture is ideal.

3Away from Obstacles

Keep the device away from:

• 🧱 Thick cement walls
• 💧 Aquariums and pots with water
• 🔥 Fireplaces with metal surfaces
• 📺 Televisions and monitors
• 🍳 Microwave ovens
• ☎️ Cordless phones
• 🔊 Bluetooth speakers

4Antenna Orientation

If your device has moving antennas:

• For a single-story: Place one antenna vertically and one horizontally
• For two-story: All antennas vertical
• Don't bring them close to each other.

⚙️ Settings That Make a Difference

Now we'll go into your device's settings. Don't worry, it's easier than you think!

1How to Enter Settings

📝 Step by Step:

1. Open your browser (Chrome, Firefox, etc.)
2. Type in the address bar: 192.168.1.1 ή 192.168.0.1
3. Press Enter
4. Enter your username and password (usually admin/admin)

⚠️ Attention:

If you don't know the code, look on the back of your device. There is a sticker with the information.

2Software update

The first thing you should do is check if there is a new version of the software:

• Look for a menu that says "Update" or "Update"
• Click "Check for updates"
• If there is a new version, install it.

3Frequency Band Selection

Most devices today work in two "bands":

(I.e. 2.4 GHz (Gigahertz):

• ✅ Reaches further
• ✅ Goes through walls better
• ❌ Slower speed
• ❌ More interference
• Ideal for: Remote devices, smart devices

(I.e. 5 GHz (Gigahertz):

• ✅ Much faster
• ✅ Less interference
• ❌ Shorter range
• ❌ Doesn't handle obstacles well
• Ideal for: Nearby devices, streaming, gaming

💡 The best solution:

Enable both bands with different names (e.g. "Home_2.4G" and "Home_5G"). This way you can choose depending on your device and location.

4Channel Width Adjustment

In the settings you will find an option that says "Channel Width":

• For 2.4 GHz: Choose 20 MHz (more stable signal)
• For 5 GHz: Choose 40 MHz or 80 MHz (faster)

📡 Choosing the Right Channel

Wi-Fi works on "channels" - think of them like radio stations. When too many neighbors use the same channel, congestion occurs.

1Why Change the Channel?

If you live in an apartment building, there are probably dozens of Wi-Fi networks around you. All of these can "conflict" and make yours slow.

2How to Find the Best Channel

📱 With mobile app (easy way):

1. Download a free app like "Wifi analyzer" (Android) or "Airport Utility" (iPhone)
2. Open it and you will see a graph with all the networks around you.
3. The app will recommend the best channel for you

3Changing Channel on Device

• Go to the device settings (as we saw before)
• Find the "Wireless" or "Wireless Network" menu
• Search for "Channel" or "Channel"
• Change from "Auto" to the channel you found.
• Save the changes

💡 Which channels are better?

For 2.4 GHz: Channels 1, 6 and 11 are the most stable because they do not overlap.

For 5 GHz: You have a lot more options and less crowding, so "Auto" usually works well.

🔒 Security and Speed

Proper security doesn't just protect your network - it also improves its speed!

1Check the Protection Type

In settings, find "Security" and choose:

• ✅ WPA3: The best (if your device supports it)
• ✅ WPA2: Very good for most cases
• ❌ WPA or WEP: Outdated, change them IMMEDIATELY

2Strong Password

⚠️ Very Important:

Your password must be at least 12 characters long with letters, numbers, and symbols. If someone gets on your network without permission, they will steal your speed!

3Disable WPS

WPS is a function that allows easy connection by pressing a button. However, it has security gaps. It is better to turn it off.

4Hidden Network Name?

Some say to hide your network name. DON'T do it! It does not offer real security and can create connection problems.

📱 Signal Analysis Tools

To understand exactly where your signal is strong and weak, you need the right tools.

Free Mobile Applications

📱 For Android:

• Wi-Fi Analyzer: The most popular, shows all networks and their strength
• netspot: More advanced, with heat maps
• WiFi Monitor: Simple and fast

📱 For iPhone:

• Airport Utility: Official from Apple (activate it) Wi-Fi Scanner in settings)
• Network Analyzer: Very useful for measurements

How to Use Them

1. Download one of the above applications
2. Walk through all the rooms of the house
3. Look at the signal strength indicator (in dBm)
4. Note the spots where the signal is weak.

📊 How to read the measurements:

• -30 to -50 dBm: Excellent signal
• -50 to -60 dBm: Very good
• -60 to -70 dBm: Good
• -70 to -80 dBm: Moderate (you will have issues)
• Worse than -80 dBm: Very weak

🛠️ Advanced Tips

1Setting Transmission Power

Some devices allow you to adjust how loud the signal "shouts":

• If you live in a small apartment: Reduce the power a little (70-80%) to reduce interference
• If you have a big house: Leave it at 100%

2Quality of Service (QoS)

This setting allows you to prioritize specific devices or activities:

• Give high priority to video calls and streaming
• Average for internet browsing
• Low for file downloads

3Creating a Visitor Network

Create a separate network for your friends:

• ✅ Protects your personal devices
• ✅ You can set a speed limit for it
• ✅ Easy to close when you don't need it

4Wi-Fi schedule

Many devices have a timer. You can:

• You turn off Wi-Fi at night to sleep better.
• You limit your children's internet access to specific times.
• You save energy

5Disable Old Templates

In the settings you will see options like 802.11b/g/n/ac/ax. These are the Wi-Fi "standards":

• ❌ b/g: Too old, too late - turn them off
• ✅ n: They keep it for compatibility.
• ✅ Ac: Modern and fast - they keep it
• ✅ ax (6 WiFi): The newest - if you have it, activate it

💡 Tip:

If all your devices are relatively new (less than 5 years old), turn off b/g. You'll gain speed!

💡 Additional Solutions

1Aluminum Foil (DIY Solution!)

Yes, you read that right! You can make a reflector:

1. Take a piece of aluminum foil 30x30 centimeters.
2. Wrap it around a piece of cardboard to make it stand up.
3. Place it behind the device, in the direction you DO NOT want signal.
4. The signal will "bounce" in the opposite direction

⚠️ Attention:

This is a temporary solution and may not work in all cases. Try it and see if you see a difference!

2Expansion with Old Router

If you have an old router that you don't use:

• You can turn it into a "signal repeater"
• Put it in a room with a weak signal
• Connect it with a network cable to the main router (better) or wirelessly

3Powerline Adapters

These devices transmit the internet through the electrical installation:

✅ Advantages:

• They reach anywhere there is a power outlet
• Stable connection without interference
• Easy installation

4Mesh WiFi Systems

If none of the above works, you may need a Mesh system:

• Many small devices working together
• They create a single network
• Ideal for multi-story or large homes
• More expensive solution but very effective

5Network Cable (Ethernet)

For stationary devices (computer, Smart TV):

💡 The best solution:

Wired connections! It's faster, more stable, and doesn't affect other wireless devices. A good Cat6 cable costs a few euros.

🔄 Maintenance and Inspections

Monthly Checklist

• ✓ Clean the dust from the device and antennas
• ✓ Check for software updates
• ✓ See which devices are connected (is someone "stealing" your Wi-Fi?)
• ✓ Do speed tests in different locations

Restart

Once a month, restart your device:

1. Unplug the power cord.
2. Wait 30 seconds.
3. Re-fill
4. Wait 2-3 minutes for it to fully boot

💡 Why it helps:

Restarting clears the device's memory, fixes minor problems, and can improve performance.

📊 How to Measure Your Speed

Correct Speed ​​Test

1. Close all programs that use the internet.
2. Disconnect all other devices from the network.
3. Go to fast.com ή speedtest.net
4. Take the test 3 times and take the average.

What Speed ​​Do You Need?

• 📧 Email, browsing: 1-5 Mbps
• 📺 SD streaming: 3-5 Mbps
• 📺 HD streaming: 5-10 Mbps
• 📺 4K streaming: 25-40 Mbps
• 🎮 Online gaming: 10-25 Mbps (low ping more important)
• 💼 Teleworking, video calls: 10-20 Mbps

⚠️ Important Note:

The speed your provider promises you is the MAXIMUM. On Wi-Fi you will get 40-60% of that speed. With cable you will get much closer to the promised speed.

🔧 Solutions for Common Problems

Problem 1: The signal is there but the internet is slow

Try out:

• Change Wi-Fi channel
• Turn off devices you are not using.
• Enable QoS for priorities
• Test with a cable - if it's fast, the problem is Wi-Fi

Problem 2: Constant disconnections

Try out:

• Router software update
• Change to fixed channel (not Auto)
• Disable energy saving on your device
• Channel bandwidth reduction to 20 MHz

Problem 3: The signal does not reach a room

Try out:

• Move the device closer or higher
• Use 2.4 GHz instead of 5 GHz
• Try the aluminum foil trick
• Consider expanding with powerline ή mesh

Problem 4: Wi-Fi drops when I use the oven

Why does it happen:

The microwave oven operates on the same frequency (2.4 GHz) as Wi-Fi and creates interference.

Solution:

Use the 5 GHz network or move the device away from the kitchen.

🎯 Final Tips

The 10 Golden Rules for Strong Wi-Fi:

1. Central position: The device in the center of the house
2. Height: At least 1-2 meters from the floor
3. Free space: Away from obstacles and devices
