Selectable frequency range: 2.4 GHz or 5 GHz
Modern smartphones vivo support operation in two frequency ranges. The choice between them depends on the tasks and environmental conditions. Range 2.4 GHz is more common, it has better penetration through walls, but is often overloaded with signals from neighbors and household appliances.
Range 5 GHz Provides significantly higher data transfer rates and is less susceptible to interference, but has a shorter range and is less able to penetrate obstacles. If your laptop is in the same room as your phone and you need high speeds for downloading files or video conferencing, 5 GHz is the optimal choice.
To switch the band, find "AP Band" or "Frequency Band" in the access point settings. Select the desired value and save the settings. Please note that older laptop models may not support the 5 GHz network and will simply not see the access point after switching.
| Parameter | 2.4 GHz | 5 GHz |
|---|---|---|
| Transfer speed | Up to 150-300 Mbps | Up to 400-800+ Mbps |
| Range | High | Medium/Low |
| Permeability of walls | Good | Bad |
| Airtime congestion | High | Low |
What should I do if my laptop doesn't see the 5 GHz network?
If you've switched your access point to 5 GHz and your laptop can't find the network, it's likely that its Wi-Fi module doesn't support this standard. In this case, you'll need to go back to your phone's settings and force it to use the 2.4 GHz band. Most modern laptops support both bands, but devices older than 5-7 years may only work in 2.4 GHz.
Optimizing traffic and battery consumption
