If you are trying to connect to an online server in Call of Duty, you have probably noticed that you will wait through “Awaiting Connection” for about 10 or 11 seconds, then the connection times out. This is due to the Activision master server browser having issues (presumably because Call of Duty 4 has been more popular than they thought).
A quick remedy for this connection problem is to set the timeout to be longer in your CoD 4 multiplayer config file, found in the profile folder of your player. For example, mine is:
C:\Program Files\Activision\Call of Duty 4 - Modern Warfare\players\profiles\string\config_mp.cfg Yours could be C:\Program Files\Activision\Call of Duty 4 – Modern Warfare\players\profiles\YOURNAME\config_mp.cfg
Open the file up in notepad or any other text editor (I use ConText), and add this line:
seta cl_connectionAttempts "30" – this will give the connection 30 seconds, and normally fixes the problem.
Happy Call of Duty 4 playing!
