I did a Skype test call today at midday(You speak to Skype and they send a recording of your message back to you) and the message I received back was very distorted (incomprehensible.)The Skype stats showed a high rate of sending packet errors.
I messed around a lot with no effect then tried again at 17:00 and now it worked fine and the sending packet errors were gone:
How can I account for this? What can cause sending packet errors?
