How to set up Wi-Fi Assistant for maximum efficiency
Just turning on a function isn't enough -- to make it work optimally, you have to set it up correctly. Here are the key parameters and their recommended values:
1. Priority of 5 GHz networks
If your router supports both frequencies (2.4 GHz and 5 GHz), turn on priority for 5 GHz.
- ⚡ Higher Internet speed (up to 1 Gbps vs. 150-300 Mbps at 2.4 GHz).
- 🎮 Less latency (important for online gaming and video calls).
But remember: 5GHz signals are worse at passing through walls, so away from the router can be unstable.
2. Autoconnection to known networks
This option allows the phone to automatically connect to networks you have previously connected to (e.g. at home, work, cafes).
⚠️ Warning: If you are often in places with open networks (airports, shopping malls), the phone can connect to them automatically, which is not safe. VPN.
3. Network scanning in the background
If you turn this on, the phone will be constantly looking for new networks, even when the screen is off. This is convenient, but it consumes a lot of battery.
- 🔋 Disable if you rarely move between networks.
- 🔍 Enable if you frequently switch between different access points (e.g., in an office with multiple routers).
4. Notifications of new networks
This feature shows notifications when the phone detects an open network nearby, and it is recommended to turn off, as:
- 📵 Most open networks are not secure.
- 🛑 This can lead to accidental connection to fraudulent access points.
After setting up, remember to restart your phone so that the changes take effect.

| The phone does not switch to a stronger network. | Incorrect operation of the signal analysis algorithm | Disable and turn on the Wi-Fi assistant again, then restart the device |
| Permanent connections to weak networks | The list of priority networks are outdated access points | Remove unnecessary networks from saved (Settings) → Wi-Fi → Save networks) |
| Quick battery discharge after switching on assistant | Active scanning of networks in the background | Disable the option "Scan Networks in the Background" |
