So I have researched this quite a bit, even gone through the posts here, and I'm still seeing strange issues. Trying to connect to my MacBook Air with Mavericks installed 10.9.13a603 from a windows 7 laptop. Both are on the same network, Mac via WLAN, Win7 via Wired LAN. As soon as I attempt to connect to the Mac, the WiFi connection gets dropped on the Mac. (WiFi is using WPA Enterprise). If I reconnect the wireless quick enough while the VNCViewer (RealVNC) is still trying to connect, I can get a session up. I have tried both screen sharing, as well as remote management. The session is also very laggy, when I close an application from the viewer, it instantly closes on the mac, but takes nearly a full second, sometimes more, to refresh the screen on the viewer. All other network functions are fine from the Mac, speeds are great to the internet, so Im not just seeing issues with WLAN degradation. What spooks me is the instant disconnect of the WiFi when the viewer attempts to attach. VNC Connection Settings: No Scaling Enable Toolbar Best Quality (also tried less quality) Enable Keyboard Pass special keys direct enable mouse menu key: none NOTE: I also had this issue when I had issues with my Mini connected in the same way running mountain lion, minus the wifi drop issue. I could occasionally get a connect, but was laggy. I have also tried connecting while the Mac is logged out as suggested by some, and same result. Thoughts?
