How much traffic does Wi-Fi sharing from a laptop consume?

Sharing itself doesn't consume traffic—only the data used by connected devices is consumed. However:

• 📊 The laptop in access point mode consumes 5-15% more traffic due to service packets (for example, to maintain the connection).
• 🔋 If background updates (Windows Update, cloud backups) are running on connected devices, traffic may increase significantly.
• 📵 On tariffs Megaphone "Unlimited" internet often has hidden restrictions on your modem. For example, after 100 GB, the speed may drop to 128 kbps. Check the terms in your personal account or by calling 0500.

Is it possible to share Wi-Fi from a laptop if it has a VPN enabled?

Yes, but:

• 🔒 If the VPN is connected at level systems (for example, through built-in Windows settings), all traffic from connected devices will go through the VPN. This may slow down speeds.
• 🛡️ If the VPN is used only in the browser (extension), it will not extend to other devices.
• ⚠️ Some VPNs (for example, ProtonVPN or NordVPN) are blocking traffic distribution. In this case, disable the VPN or configure exceptions in its settings.
