===Diagnostics you can run from a computer:===
These are tests you can from your computer, some of them (eg the ping) will need you to use a command prompt or terminal to enter the commands. Do get in touch if you need help with how to do that.
#'''Ping tests:''' <br> running ping tests from the 'command line' can help see if there is any strange loss or latency. <br> ''Expected results'': The ping results should show 0% loss and the latency should be below 20ms, any thing else would need further investigation.
## '''ping your router:''' <br> This will test your local connection. eg, if your router (gateway) is 192.168.0.1 then run this to send 100 pings: <syntaxhighlight>(on windows) ping -n 100 192.168.0.1</syntaxhighlight> <syntaxhighlight>(on Mac) ping -c 100 192.168.0.1</syntaxhighlight> and let us know the last few lines containing the results, which show any loss, the latency and jitter, eg:<syntaxhighlight>
