• 🔄 Make sure the router is plugged into a power outlet and the power and Wi-Fi indicators are lit.
• 📡 If you use mesh system (For example, Google Nest Wi-Fi), wait until the nodes are synchronized (the indicators will stop flashing).

✅ Basic router setup:

• 🖥️ Connect the router to your computer via cable (or via old Wi-Fi, if it still works) and log into the control panel at 192.168.0.1 or 192.168.1.1.
• 🔑 Check that the Wi-Fi network included (on the menu Wireless → Basic Settings).
• 📛 Write down or take a photo of the network name (SSID) and password - you will need them for your phone.

Important! If you haven't changed your router settings, the network name and password are located on a sticker on the bottom of the router (e.g. TP-Link_1234 And admin1234). But the factory data is often the same for different devices - they are easy to find, so after connecting the phone Be sure to change your password (more on this in section 5).

2. Step-by-step instructions for Android

• 🚨 Attention! If the network is not displayed, check if it is hidden in the router settings (parameter Hide SSID should be turned off).

🔐 Step 3: Connect to the network:

• Click on the network name, enter the password (case sensitive!) and tap Connect.
• If an error occurs "Authentication...", check if the password or security type is correct (should be WPA2-PSK or WPA3).

⚙️ Step 4: Adjust settings (if necessary):

• Once connected, click on the network name → Change network → turn on Auto-connection.
• If the Internet doesn't work, check your settings. IP (should be there) DHCP).

• Go to Wireless → Security and set a new password (at least 12 characters, with numbers and special characters).

🛡️ Step 2: Choose the Right Security Type:

• Use WPA2-PSK or WPA3-PSK (if the router supports it).
• 🚫 Never choose WEP or Open network - they are hacked in seconds.

📡 Step 3: Disable unnecessary features:

• Turn it off WPS (vulnerability to brute force attacks).
• Hiding SSID does not protect against hacking, but can make it difficult for legitimate devices to connect.

📱 Step 4: Set up a guest network (optional):

• Create a separate network for guests with limited access to local devices.
• Set a speed limit to prevent guests from eating up your bandwidth.

6. Additional settings for stable operation

If your Wi-Fi is working but the speed is slow or the connection keeps dropping, try optimizing your router and phone settings.

📶 Optimizing the Wi-Fi channel:

• 📊 Use apps like Wi-Fi Analyzer (Android) or AirPort Utility (iOS) to find the least crowded channel.
• For 2.4 GHz, select channels 1, 6 or 11 - they do not intersect.
• On 5 GHz you can use any channel, but avoid DF (radar frequencies).

🔄 Configuring DHCP:

• In the router panel, find DHCP Settings and set the IP address range (eg. 192.168.1.100-199).
• This will prevent conflicts if you have many devices.

📱 Phone settings for better communication:

• On Android, disable Adaptive Wi-Fi (in network settings) if the signal is unstable.
• On iPhone, turn on Private Wi-Fi address (in network settings) to make it more difficult to track your device.

⚡ Problems with speed?

• Check if there are any other devices connected to your network (in DHCP Client List on the router).
• If you use dual band router (2.4 + 5 GHz), try disabling 2.4 GHz - there is less interference on 5 GHz.

How to check who is connected to your Wi-Fi?

Go to your router's control panel → DHCP Client List or Attached DevicesIf you see unfamiliar MAC addresses, change the network password.

7. Frequently asked questions and answers

❓ Why won't my phone connect to Wi-Fi even though the password is correct?

This may be due to:

• Incorrect type of security (for example, the router is configured to WPA3, and the phone only supports WPA2).
• MAC filtering (in the router settings, access may be allowed only to certain devices).
• Limitation on the number of devices (on some routers the limit is 10-20 gadgets).

Solution: Check your router settings or reset it to factory settings (button Reset on the back panel).

❓ How do I transfer Wi-Fi settings from an old router to a new one?

Unfortunately, automatically It's impossible to transfer settings—each router has its own firmware. But you can:

• Take a photo of the old settings (network name, password, MAC addresses devices).
• Download a backup copy of the configuration (if the old router supports exporting settings).
• Manually reproduce the main parameters (SSID, Security, DHCP).

❓ Do I need to change the network name (SSID) after replacing the router?

It's not necessary, but recommended, If:

• You want devices (TV, printer) to automatically connect to a new network with the same name.
• You are using roaming between multiple access points (for example, in a big house).

If you leave the old name, the phone will connect automatically, but there is a risk of conflict if the device memory still contains data from the old network.

❓ Is it possible to connect a phone to a router without a password?

Technically yes, but that's extremely unsafeIf you need to share the Internet with guests, it's better to:

• Create guest network with a separate password.
• Use WPS (but turn this feature off after connecting!).
• Turn on QR code for connection (available on some routers) ASUS And TP-Link).

❓ Why are some devices not connecting after replacing the router?

The reasons may be different:

• Outdated firmware on the device (for example, an old printer or Smart TV).
• Incompatibility of standards (the router is running on 802.11ac, and the device only supports 802.11n).
• IP address conflict (if the new router distributes addresses from a different range).

Solution: Check your settings Wireless Mode on the router - install 11b/g/n mixed for maximum compatibility.

If after all these steps the Wi-Fi on your phone still doesn't work, check:

• 🔌 Does the Internet work on other devices (computer, tablet)?
• 📱 Is it turned on on your phone? Airplane mode or Saving traffic.
• 🔄 Does your antivirus (for example) block it? Kaspersky or Avast) connecting to a new network.

As a last resort, reset the network settings on your phone:

• On Android: Settings → System → Reset → Reset Wi-Fi, mobile network, and Bluetooth settings.
• On iPhone: Settings → General → Transfer or reset iPhone → Reset network settings.
