WTFast Was Working Good Before, But Why Is It Slower Now?
The most common mistake is starting WTFast and selecting a particular WOW realm, but then after loading WOW, logging into a different WOW realm than was selected. Your WTFast connection is optimized based on the WOW realm you are playing on; if you want to change realms, you should reload WTFast and select the new server that you want to play on before loading WOW again. We also recommend trying a different city/region to see if this helps improve your results with WTFast.
