After successfully logging in, you'll see the main control panel page. This displays key parameters, including internet connection status, a list of connected devices, and the firmware version.

Basic Internet setup (WAN)

The first step is to set up your internet connection. Go to the section Advanced → Network → WAN (or Basic → Internet (in the English version). Here you need to specify the parameters provided by your provider. Typically, these are:

• 📡 Connection type: Dynamic IP (DHCP), Static IP, PPPoE, L2TP or PPTPCheck with your provider if you don't know.
• 🔑 Username and password (for PPPoE/L2TP/PPTP).
• 🔢 Additional options: MTU (usually 1500), VLAN ID (if required).

For most providers (eg. MTS, Megaphone, Dom.ru) fits Dynamic IPIf you have Rostelecom or Beeline, most likely it will be required PPPoE with login/password from the contract.

If the internet still doesn't work after saving the settings, check if the router's MAC address matches the one registered with your provider. In the section Advanced → Network → MAC Clone You can copy the address from your computer or enter it manually.

What should I do if my ISP uses MAC address binding?

If your ISP binds your internet connection to the MAC address of your old device (modem or previous router), follow these steps:

1. Find out the MAC address of the old device (usually indicated on a sticker or in the web interface).

2. In the control panel Mercusys AC10 go to Advanced → Network → MAC Clone.

3. Enter the MAC address manually or clone it from a connected computer (button Clone MAC Address).

4. Save the settings and reboot the router.

After this, your internet should work. If not, contact your provider and ask if additional connection is required.

Setting up a Wi-Fi network: name, password, and security

Now let's set up the wireless network. Go to the section Basic Setup → Wireless Mode (or Wireless). Here you can:

• 📛 Change network name (SSID): Create a unique name to distinguish it from other networks. Avoid using personal information (such as your last name or address).
• 🔒 Set a password: minimum 8 characters, with capital letters, numbers and special characters (eg Wifi@Home2026!).
• 📶 Select operating mode: For maximum compatibility, please select 11ax/b/g/n/ac (or 11ac/n/a 5GHz for the 5 GHz range).
• 🛡️ Protection: use WPA2-PSK or WPA3-PSK (if supported by devices). WEP unsafe!

For Mercusys AC10 two networks are available:

• 2.4 GHz: Better through walls, but susceptible to interference from other devices. Suitable for smart home (lamps, sensors).
• 5 GHz: High speed, but shorter range. Ideal for streaming video, gaming, and downloading.

We recommend using different names for ranges (eg MyWiFi_2G And MyWiFi_5G) to see which network you're connecting to. You can make the password the same for convenience.

⚠️ Attention: if you enable the option Hide SSID (hide the network name), this won't improve security—attackers will still be able to detect the network. It's better to use a strong password and update it regularly.

Additional settings: guest network, parental controls, and QoS

After the basic setup, you can optimize the router's performance to suit your needs. Let's take a look at the most useful features:

Guest network

If you have frequent guests, create a separate network with limited access:
