The problem you meet on Dreamweaver CS5.
Sometimes happens that when we work in Adobe Dreamweaver (newer version of CS3), to encounter problems at upload-ul FILES pe server. More precisely, if we have Dreamweaverthe connected by FTP the web server (Remote Server) after we do MODIFICATION and save an file (index.php eg) the dialog box appears with the message “Waiting for server…“, and after a few seconds the message of error timeout“.
This is a problem appears behind connection errors Internet between the application Dreamweaver and the exit on the port of FTP (21), again solving they stay in Configuring routeracquis wireless. If you use it Connection on direct (by cable), it is unlikely that this problem will appear, and if it appears, assured that you have set to Dreamweaver > “Remote Server” > “More Options” > “Use IPv6 Transfer Mode” and “Use FTP performance optimization“.
In order to solve the error “Waiting for server” In case of a connection by wireless, you will have to log in to router and to give you Unlimited access on port 21 (Ftp) to your computer / laptop somewhere in Firewall settings (depends depending on the router) you will find an option of “Port Forwarding” Where will you need to set the connection “trust” On the FTP 21 port for the computer you use Dreamweaver. Unfortunately we cannot give you the exact steps, because each model of router has different interfaces and settings. If you do not have this problem and do not do it, we are waiting for you with comments.
In my case I preferred to use DMZ (Demilitarized Zone), but if you use this option it is good to use a local firewall (installed on your PC).

Router Firewall DMZ (Demilitarized Zone):
The DMZ (Demilitarized Zone) option lets you set a single computer on your network outside of the router. If you have a computer that cannot run Internet applications successfully from behind the router, then you can place the computer into the DMZ for unrestricted Internet access.
Note: Putting a computer in the DMZ may expose that computer to a variety of security risks. Use of this option is only recommended as a last resort.
If the dialog box appears with the message “Waiting from server…” and the operation ended with “timeout”, it is recommended to saved in a text editor Changes made in work file. I arrived several times in the situation to save a file from Dreamweaver on the server, and after the error message the file on the server became Blank. At his reopening I found that we had nothing in it and I had to restore everything.
