Normally when you are having drop outs, it is due to UDP packet loss on the connection. Aces High uses UDP for the VOX portion to reduce overhead, but when a packet is lost, it is lost.
Three things to try;
1) Use Ping Plotter to run a plot to the server, using the UDP protocol. See if there is any packet loss along the way. If there is, that is the culprit.
2) If you are behind a router, power cycle the router. Consumer grade routers need to be rebooted from time to time.
3) Place your name in the 'V' box to test your own connection. The problem may not be you at all. If you hear yourself without any breakups, the problem lies with the person claiming you are breaking up.
