|Ping can, and will vary with how congested a network is. The higher the load, the slower the ping time and the greater the latency.|
If everything is working correctly (ie: you're able to surf ok, game ok, download ok, etc) then there's nothing wrong with your connection other than a high ping which usually doesn't mean much.
If you're having connectivity issues you need to contact your provider as there's nothing we can do about it.....anymore than we can "fix" your ping issue.
It matters not how straight the gate,
How charged with punishments the scroll,
I am the master of my fate;
I am the captain of my soul.
