Ping on Windows :

Click 'Start' then 'Run' and type 'command' into the run box. This will bring up a DOS command prompt. Type :

Code:
ping -n 100 hostname
hostname = Your server (e.g. uk1.internet-radio.com) without the port.
-n 100 = Ping 100 times​

Ping on Mac OS X / Linux :

Load up a terminal and Type :

Code:
ping hostname
After you have pinged at least 100 times you can press the ctrl + c keys and it will stop and output your ping summary.

After your ping has been completed you should see a summary which looks something like this :

100 packets transmitted, 100 received, 0% packet loss, time 2001ms
rtt min/avg/max/mdev = 12.384/13.468/14.533/0.877 ms
Essentially if there is a problem packets will be lossed (i.e. 100 packets transmitted 95, received is a 5% packet loss).

We recommend resetting your broadband router and perhaps restarting your machine if you get packet loss. Unfortunately it could be a problem at your ISP's level which would be out of yours and our control and may require you to wait for it to be fixed. You could try contacting your ISP and sending them the results from your ping but it is likely the issue will be fixed before long.
