Guild Wars has a built-in diagnostic utility. This test captures computer and network diagnostic information from a variety of sources and stores it in a text file. The Guild Wars Support Team uses this information to locate network issues, detect system configuration problems and identify driver version problems. It takes about a minute to run the diagnostic test; it can be run while Guild Wars is running (that is, without exiting the current game).
We ask that if you are using a router, hub, or switch, to first disconnect this device and connect directly to your modem before running this utility. You may have to reboot your modem and/or computer to reestablish your Internet connection.
To run the diagnostic, perform the following steps.
1. Click Start.
2. Click Run.
3. Click Browse and select your Gw.exe program. It will be in "C:\Program Files\Guild Wars" by default. You can reach this through "My Computer" > "Local Disk C:" > "Program Files" > "Guild Wars".
4. The Run window should now read:
"C:\Program Files\Guild Wars\Gw.exe"
Modify the line in the Run window to read:
"C:\Program Files\Guild Wars\Gw.exe" -diag
5. Press OK to run the test.
You will see a small window that gives the status of the testing. Please wait for all of the tests to finish. When it is done, click Close. The test will create a new file in your Guild Wars folder (again, by default this is "C:\Program Files\Guild Wars") called NetworkDiag.log. You can review this file yourself, or use the Ask a Question link to send the NetworkDiag.log file to Technical Support as an attachment.
