Beware the Sulfites. Sensitivity to sulfites is common among asthmatics. For me, an allergic reaction can result in a severe asthma attack. Dried fruits are usually responsible for the reactions. As with all processed or manufactured food items, I consistently check labels.
In some rare cases, dropped frames can be caused by an old network adapter driver doing a poor job of handing the high speeds being consumed. It's not a bad idea to just check to see if there are any new drivers for your network adapter, just to be sure.
Switching another server will resolve many dropped frames/connection issues. Just because the server you have selected is the closest to you, or pings the best to you, does not mean it will give you the best connection.
