1. What equipment is needed to connect to Wi-Fi from Garant?

Before you begin setting up, make sure you have everything you need. Provider Guarantee In most cases, we provide clients with a ready-made equipment kit, but sometimes additional devices may need to be purchased. Here's what you might need:

• 📶 Modem or ONT terminal (if connected via GPON technology). Typically provided by the provider, models vary by region: Huawei HG8245H, ZTE F660 or Sercomm RV6699.
• 🖧 Router with standards support 802.11ac or Wi-Fi 6. The garant often offers rental of its devices (for example, Keenetic Lite or TP-Link Archer C6U), but you can also use your own.
• 🔌 Cables: optical patch cord (for GPON), twisted pair Cat.5e/Cat.6 (for Ethernet connection), power supply for the router.
• 📱 Tuning device: A laptop, smartphone, or tablet with Wi-Fi support. Some router models may require an Ethernet cable for initial configuration.

Important: If you use own router, check its compatibility with the network GuaranteeSome models (especially older ones) do not support the protocol. PPPoE or DHCP Binding by MAC address, which may result in inaccessibility. A list of recommended devices is usually published in the subscriber's personal account.

⚠️ Attention: In 2026 Guarantee began the transition to a new authentication system 802.1X For corporate clients. If your plan is in the business segment, please check with support to see if additional software is required for setup.

2. Preparing for connection: checking cables and settings

Before connecting the router, make sure all physical connections are correct. Errors at this stage are the most common cause of internet failure. Follow these steps:

1. Connect the optical cable (if you have GPON) to the port PON on the ONT terminal. For an Ethernet connection, use the port WAN on the router.
2. Connect the ONT terminal to the router with an Ethernet cable (port LAN on the terminal → port WAN on the router).
3. Connect the power supply to the router and plug it in. Wait for the indicators on the router to stabilize (usually 1–2 minutes).

If you have combined connection (GPON + telephone line), check that the cable from the splitter is connected to the port PHONE on the ONT terminal. Otherwise, the phone service will not work, even if the internet is available.

We also recommend checking in advance in your personal account or with a support specialist. Guarantee the following parameters:

• 🔢 Connection type: PPPoE, DHCP or Static IP.
• 🔑 Login and password for access (if used) PPPoE).
• 🖥️ MAC address of the bound device (if required).

⚠️ Attention: If you are connecting via technology GPON, don't use cheap optical cables longer than 5 meters—this can lead to a drop in speed or connection failure. The best option: cable LC-LC with crimping 9/125 µm.

3. Configuring your router to work with Garant: step-by-step instructions

The setup process depends on the router model and connection type. We'll cover a universal algorithm that works for most devices (using the example TP-Link Archer C6 And Keenetic Lite). If you have a different model, the principles will remain the same, but the menu item names may differ.

First, connect to the router:

• By cable: connect the port LAN router with a computer network card.
• By Wi-Fi: Find a network with the router model name (e.g. TP-LINK_1234) and connect to it. The password is usually found on the device's sticker.

Next, open your browser and enter the router's IP address in the address bar. Standard addresses:

• 192.168.0.1 (for most TP-Link, D-Link models)
• 192.168.1.1 (for Keenetic, Asus, Zyxel)

Log in using your login and password (default - admin/admin or admin/password from sticker).

Now let's move on to setting up your internet connection. In the router menu, find the section Network → WAN or Internet and select the connection type that is used Guarantee:

After saving the settings, reboot the router and check your internet connection. If the indicator WAN If the light is not on or flashing red, go back to the settings and make sure all parameters are entered correctly.

4. Setting up a wireless Wi-Fi network

Once the internet connection is working on your router, you can start setting up Wi-Fi. Open the section Wireless network or Wi-Fi in the router menu. Here you need to set the following parameters:

• 📛 Network name (SSID): Come up with a unique name, avoiding personal information. For example, HomeNet_5G instead of Ivanov_Family.
• 🔒 Security type: select WPA2-PSK or WPA3-PSK (if supported) Never use WEP or open network!
• 🔑 Password: minimum 8 characters, using letters, numbers, and special characters. Example: G4r@nt_WiFi_2026.
• 📶 Channel and width: For 2.4 GHz select a channel 1, 6 or 11 (least loaded). For 5 GHz use channel width 40 MHz or 80 MHz (if devices support it).

To improve coverage, turn off the feature. WPS (it's not safe) and activate it Beamforming (if available in the settings). If you have a dual-band router, set up separate networks for 2.4 GHz And 5 GHz - this will allow you to connect devices to the optimal frequency.

How to choose the least crowded Wi-Fi channel?

Open the app on your phone Wi-Fi Analyzer (Android) or NetSpot (iOS). It will show the channel load in your area. Choose the one with the least overlap with neighboring networks. In urban areas 2.4 GHz usually overloaded, so for stable operation it is better to use 5 GHz (if your devices support it).

Don't forget about the guest network if you need one. Find the section in your router settings. Guest Network and activate it. Limit the speed for guests (for example, to 10 Mbps) and disable access to the local network - this will protect your personal data.

5. Typical mistakes and their solutions

Even with proper setup, problems can still arise. We've compiled the most common errors and how to fix them:

If none of the methods helped, check router logs (chapter System Tools → Journal). Often specific errors are indicated there, for example, PPPoE timeout (authentication problems) or DHCP lease failed (unable to obtain IP address). This information will be useful when contacting support. Guarantee.

⚠️ Attention: If the Internet is lost after resetting the router, do not try to change the settings yourself VLAN ID or PVID This may result in the port being blocked on the provider's side. Please contact support. Guarantee and clarify the correct values.

6. Optimize Wi-Fi speed and stability

To ensure your wireless network works at its best, follow these guidelines:

• 📍 Router locationPlace it in the center of your apartment, 1–1.5 meters above the floor. Avoid placing it close to microwaves, cordless phones, and other sources of interference.
• 🔄 Firmware update: Check for updates for your router regularly. New firmware versions often improve stability and speed.
• 📊 Control of connected devices: Limit the number of devices connected simultaneously. For example, to watch 4K video, one device requires up to 25 Mbps, and there may be several of them.
• ⚡ Using Mesh Systems: If the coverage area is large, consider installing Mesh routers (For example, TP-Link Deco or Keenetic Hero). They provide seamless roaming between access points.

For advanced users: you can activate it in your router settings QoS (Quality of Service)to prioritize traffic. For example, give maximum priority to video calls (Zoom, Skype) and streaming (Netflix, YouTube), and limit torrent downloads.

Important: If you're using a Garant plan with speeds above 300 Mbps, make sure your router supports Wi-Fi 5 (802.11ac) or Wi-Fi 6 (802.11ax). Otherwise, your actual wireless speed will be limited to 100–150 Mbps.

7. Wi-Fi Security: How to Protect Your Network from Hacking

An open or poorly secured Wi-Fi network is an easy target for hackers. They can not only steal your traffic but also access your personal data. Here are some basic security measures:

• 🔐 Complex password: Use a combination of 12+ characters with uppercase letters, numbers, and symbols. Example: G@r4nt_Secure_2026!.
• 🔄 Changing your password regularlyChange it every 3-6 months. This is especially important if you have guests connecting to your network.
• 🚫 Disabling WPS: This function is vulnerable to brute-force attacks. It is better to use WPA3.
• 📋 MAC address filtering: You can control which devices are allowed to connect to the network in your router settings. However, this method isn't foolproof, as MAC addresses can be spoofed.
• 🛡️ Disabling remote control: in the section Administration Disable access to router settings from the Internet.

Additionally, we recommend disabling UPnP (Universal Plug and Play) - this feature is often exploited by viruses to penetrate local networks. If you need to transfer files between devices, use FTP or Samba with strong passwords.

To check the security of your network, you can use mobile applications such as Fing or Network AnalyzerThey will show all connected devices and help identify unauthorized access.

8. How to contact Garant support if nothing helps

If you've tried everything but the problem persists, it's time to contact technical support. GuaranteeHere's how to do it most effectively:

1. Prepare the data:
   • Router and ONT terminal model.
   • Connection type (PPPoE/DHCP/Static IP).
   • Description of the problem (e.g. "Wi-Fi works, but the speed is below 10 Mbps").
   • Screenshots of errors from the router log (if available).

Contact methods:

• 📞 Hotline number: usually 8-800-XXX-XX-XX (check on the website) Guarantee for your region).

• If a support specialist asks you to run diagnostics, follow their instructions. They can often remotely check the line and router status.

Tip: Before calling support, reboot your router and check if you've reached your data plan's data limit. Sometimes this is the cause of low speeds.

If the problem is on the provider's side (for example, a damaged cable or a failure at the station), check with a specialist application number and an estimated time to fix the problem. This will help you track the repair status.

❓ How can I find out what type of connection Garant uses in my home?

The connection type is specified in the contract or personal account. It can also be determined by the equipment:

• If you have GPON, then an optical cable is connected to the apartment, and you use an ONT terminal.
• If Ethernet, then the twisted pair cable is connected directly to the router port WAN.

In case of doubt, call support Guarantee and clarify.

❓ Can I use a router from another provider (for example, Rostelecom) with Garant?

Yes, but two things need to be taken into account:

1. The router must support the connection type that is used Guarantee (PPPoE, DHCP etc.).
2. Some tariffs Guarantee require MAC address binding. In this case, you'll need to clone the old device's MAC address or register a new one in your personal account.

We recommend that you check the router's compatibility with support before purchasing it.

❓ Why is the Wi-Fi speed lower than the cable speed after connecting to a router?

This is a normal situation, as the wireless network has limitations:

• Standard Wi-Fi 4 (802.11n) maximum gives 150–300 Mbps.
• Interference from neighboring networks reduces actual speed.
• Outdated router firmware may limit throughput.

To improve speed:

• Switch to 5 GHz (if devices support it).
• Update your router firmware.
• Reduce the number of connected devices.

How do I reset my Garant router to factory settings?

To reset, press and hold the button Reset (usually located on the rear panel) for 10-15 seconds until the indicators start flashing. After this, the router will reboot and all settings will be reset. You can access the control panel using the standard IP address (192.168.0.1 or 192.168.1.1) with login/password admin/admin.

❓ What should I do if Garant blocked my access due to non-payment?

If your internet access is suspended, please follow these steps:

1. Check your personal account balance and top up your account.
2. Wait for automatic access restoration (usually takes 10-30 minutes).
3. If the Internet does not appear, reboot the router.
4. As a last resort, contact support and check the blocking status.

Please note: when blocked for debt, some providers limit the speed to 1 Mbps instead of a complete shutdown.
