Ping 300

[annieigma]

Hi,
just done a speed tewst, as running slow, ping just over 300, download 900 kbs. normally i get a ping of 55, and download of 1.5m. what is the ping in relation to the download speed. I asked this before, but need simple expanation pleas, as need to know if O.H. is watching netflix, would this affect my speed on the desktop computer, as I thought the incoming bandwidth would reflect the received speed, no matter how many computers were on line in my property.
please enlighten me.
