2. Problems on the phone side: settings and errors

Sometimes your phone can't detect Wi-Fi due to software glitches or incorrect settings. Here's what to check:

📱 Android: Reset network settings

On Android (especially on Samsung, Xiaomi, Honor) Resetting network settings often helps. This will delete all saved networks and restore factory settings, but will not affect your personal data.

How to do:

1. Open Settings → System → Reset (on some phones the path may be different: Settings → General settings → Reset).
2. Select Reset Wi-Fi, mobile network, and Bluetooth settings.
3. Confirm the action and restart your phone.

On some phones (especially Xiaomi, Realme, Oppo) Aggressive power saving settings may disable Wi-Fi in the background. Check:

• 🔋 Disable power saving mode: Settings → Battery → Power saving mode.
• ✈️ Make sure that Airplane mode is turned off (even if Wi-Fi is turned on separately, the connection may be blocked in Airplane mode).

3. Manually connect to a hidden Wi-Fi network

If your router is configured to hide the network name (SSID), the phone won't be able to detect it automatically. This is a common practice for increased security, but it complicates connecting new devices. Here's how to connect manually:

📱 Instructions for Android

1. Open Settings → Wi-Fi.
2. Click Add a network (or Other networks → Add manually).
3. Enter:
   • Network name (SSID): the exact name of your network (case-sensitive!). This is usually listed on the router's sticker.

If your phone can't see the network, but other devices connect fine, the problem may be with your router settings. The most common culprits are:

• 🔄 Incorrect Wi-Fi channel (overload or conflict with neighboring networks).
• 🔒 MAC address filtering (the router blocks new devices).
• 📡 The 802.11n/ac standard is disabled (old phones do not support modern protocols).
• 🔄 Firmware failure (reboot or reset solves the problem).

To change the settings, connect to the router via cable or from another device (such as a laptop) and follow these steps:

🔧 How to access Rostelecom router settings

1. Open your browser and enter the following in the address bar:
   • 192.168.1.1 (for most models Sagemcom And Sercomm),

2. Find the parameter Channel.
3. Select a channel manually 6 (or 11) and save the settings.
4. Reboot your router.

If you have a dual-band router, try connecting to the 5 GHz network (its name usually ends in _5G). It is less loaded, but not all old phones support it.

🔒 Checking MAC address filtering

Some routers Rostelecom New devices are blocked by default. To fix this:

1. Go to Wi-Fi → MAC Address Filter (or Wireless Network → MAC Filter).
2. Make sure the filter disabled or your phone has been added to the list of allowed devices.
3. Save the settings and reboot the router.

5. Compatibility issues: old phones and new routers

If you have an old phone (for example, iPhone 5/6, Samsung Galaxy S4 or earlier models), it may not support the modern Wi-Fi standards that the router uses RostelecomHere's what to do:

📱 Check supported standards

Find out what the standards are 802.11 Supports your phone:

• 802.11b/g — obsolete standards (maximum 54 Mbit/s).
• 802.11n — supports speeds up to 300–450 Mbps (most phones after 2012).
• 802.11ac — a modern standard (up to 1 Gbit/s, supported by phones after 2015).
• 802.11ax (Wi-Fi 6) — the latest standard (supported by flagships after 2019).

If your phone only supports 802.11b/g, and the router is configured to 802.11n/ac, a conflict may occur. The solution is to force the router to enable compatibility mode.

🔧 Configuring Wi-Fi mode on a router

To ensure your router supports older devices:

1. Go to the router's web interface (192.168.1.1).
2. Go to Wi-Fi → Settings (or Wireless Network → Operating Mode).
3. Find the parameter Wireless network mode (Wireless Mode) and select:
   • 802.11b/g/n mixed (for maximum compatibility),
   • 802.11b/g (if the phone is very old).

Save the settings and reboot the router.
