    • 🚫 Exclude:
      • personal information (dates of birth, names, addresses),
      • key sequences (qwerty, 12345678),
      • repeating characters (aaaa1111).

      Common mistakes when changing your password and how to avoid them

      Even experienced users sometimes make mistakes that lead to loss of Wi-Fi access or unstable network operation. Here's what you shouldn't do:

      1. Use Cyrillic characters in your passwordSome devices (especially older smartphones or printers) don't support Russian characters in the network name or password. Stick to Latin characters.

      2. Change the network name (SSID) to one that is too longThe maximum length is 32 characters, but 8–15 characters is optimal. Long names may not display on some devices.

      3. Disable encryption (install Open Network). Open networks are vulnerable to hacking, and Beltelecom may block such settings under the terms of the contract.

      4. Save your password in cloud services (For example, in Google Drive or iCloud Notes) without encryption. If your account is hacked, attackers will gain access to the network.

      5. Ignore the router reboot After changes. Some settings are only applied after a reboot.

      ⚠️ Attention: If after changing the password the internet is dropping out on all devices, check:
      • Is the cable from the provider connected to the router (indicator) Internet or WAN should be green).
      • Has it changed? network operating mode (for example, with 802.11n on 802.11ac) - some older devices do not support new standards.
      • Has it not been activated? parental control or MAC address restriction (in the router settings).

      If the problem persists, please contact support Beltelecom by phone 123 (for subscribers of Belarus).

      Additional security settings for Wi-Fi

      Changing your password is just the first step in securing your network. To make it truly secure, configure these settings on your router:

      • 🔐 Disable WPSThis feature simplifies connecting devices, but it has vulnerabilities. Find the section WPS in the settings and deactivate it.
      • 📡 Hide the SSID (network name). In the Wi-Fi settings, enable the option Hide SSID or Hide networkYour network will no longer be visible in the public list, but you can still connect to it by entering its name manually.
      • 🛡️ Enable MAC address filtering. In the section MAC Filter Specify the addresses of only those devices that are allowed to connect to the network. This isn't a panacea (MAC addresses can be spoofed), but it will add a layer of security.
      • 🔄 Update your router firmware. In the section System Tools or Software update Check that your firmware version is up to date. Outdated firmware may contain vulnerabilities.

      For advanced users: If your router supports guest network, set it up for visitors. This will allow you to share the internet without accessing the main network and its devices (printers, smart speakers, etc.).
