Q: The reasons why webcam MPEG4 player shows "can't connect to server"? 

A:  

1. Default firewall ports were disabled. (ex. 4550, 5550) 
2. Net port mapping incorrect. 
3. Dynamic IP changed. (Only use Win98 as a server) 
4. Webcam MPEG4 html does not loading properly. (error on version before 5.3) 
5. Ethernet adapter (ADSL modem must be use PPP/SLIP device) 
6. Server ports (4550, 5550)are used by another AP. 
7. Web server change download timing.(Dynamic Lan IP =1 min, Dynamic WAN IP = 5 min) 
8. Incorrect setting in webcam server setup (http, command, and data port) 
9. Client has connected to a webcam server using version 5.21 and use the "change server" button to perform another connection with webcam server using version 5.3 ~ 6.0.
