If your modem cycles or drops - Try lowering the security mode to 'most compatible' , an older OS may not have the protocols to run smooth on highest security.
If your ping jumps - go to start / run / cmd ( windows key + R in Win 10 ), type or paste --> tracert 173.208.17.14 , or the server I.P. you are checking the ping to. Each hop in the path of the server will respond with a ping. Often you will find you have been temporarily rerouted to a different main hub. Do this when your ping is at it's best.. you will know the route you should be on. Right click in the cmd screen to 'select all' then CTRL+C to copy to the clipboard. It can then be pasted into notepad or word and saved for reference or sharing.
