What is skype-wifi.exe?
skype-wifi.exe is the dedicated Skype WiFi optimization component that helps the Skype client adapt its network usage on wireless networks. It monitors connection quality, manages buffering and call signaling, and coordinates with the main skype.exe process to deliver stable voice, video, and messaging over Wi‑Fi.
This secondary process runs in its own sandbox and uses Windows networking APIs to adjust bandwidth, jitter buffers, and media playback settings. It communicates with skype.exe to preserve call quality while minimizing impact on other apps.
Quick Fact: Skype pioneered network optimization by modularizing WiFi handling; skype-wifi.exe helps maintain call quality without bogging down the main client.
