Ping Spikes when others using internet

[Survive69]

so basically, whenever someone is on the internet besides me, my ping spikes up to 1000ping and sometime dc for 20sec, it happens worst when someone is on youtube. i have read up about dynamic dns, some say it helps, some say it doesnt, should i enable dynamic dns or not? also, dont bother telling me to contact my isp because they are a-holes who blame it on us and tell us to buy stuff, thanks for any help in advance, cheers

ARe you using wifi? What speeds are you supposed to get from your ISP.

with no one else using the net, goto speedtest.net and run a test and post the results back here.
