3. Checking physical connections and cables

Up to 30% of requests to Rostelecom support are related to damaged cables or incorrect connection. Inspect:

• 🔌 power unit: Is there any foreign smell or melting? Check the voltage (should be 12V/1A or 9V/0.6A (depending on the model).

1. Try other ports (usually there are 4).
2. If none of them work, the router requires repair or replacement.

How to test a cable without a tester?

Connect the cable to another device (for example, directly to a computer). If the indicator on the network card lights up, the cable is working properly. Also, inspect the RJ-45 connectors: all 8 wires should be evenly crimped, without any kinks.

4. Firmware update: when is it necessary?

Outdated firmware may cause spontaneous reboots, slow Wi-Fi, or problems connecting new devices. Rostelecom regularly releases updates for its routers, but they aren't always installed automatically.

Most likely, the router's power supply or network card has burned out. Try a different power supply with the same specifications. If that doesn't help, the router will need to be replaced (repairs will cost more than a new device).

The Wi-Fi is working, but there's no internet. What's wrong?

Check:

1. Is the indicator light on? Internet or DSL?
2. Have the login details (login/password) in your Rostelecom personal account changed?
3. Are there any tariff restrictions (for example, the traffic limit has been reached).

If the indicator is flashing orange, there is a problem with the provider's line.

How to reset your Wi-Fi password if you forgot it?

There are two ways:

1. Reset the router to factory settings (button Reset). The password will be indicated on the sticker.
2. Go to the web interface (192.168.1.1) via cable and change the password in the section Wireless Network → Security Settings.

The router gets hot and turns off. Is this normal?

No, overheating is a sign of a malfunction. Try this:

• Place the router in a ventilated area (not in a closet!).
• Blow off dust with compressed air.
• If that doesn't help, replace the thermal paste on the chipset (disassembly required).

If the router turns off after 5-10 minutes of operation, the power supply is most likely faulty.

Is it possible to connect a different router instead of the one provided by Rostelecom?

Yes, but you need to:

1. Please check with support to see if equipment replacement is permitted under your plan.
2. Configure a new router with Rostelecom connection parameters (login/password, VLAN if needed).
3. IPTV may require additional configuration. IGMP.

⚠️ In some regions, Rostelecom binds services to the MAC address of its router. In this case, replacing it won't be possible.
