Internet download speed problem?

I have 2 problems the first being my download speed and the second being my ping. I know they are some how connected, but any assistance would be nice.

I'm downloading a 200mb file right now and my download speed usually is about 2-3MB a second, but I'm only getting up to about 1.5 mbps for about 5-10 seconds then it drops to below 700 kbps and then drops again to below 500kbps and just moments ago i was below 100 kbps. I have 35 MPBS internet through charter communications and i have never had this problem before.

As for the ping situation I used to be at 25 and below with my ping when playing games and now I can't seem to get past 45 ping(55 ping avg) and occasionally it spikes up to any from 150-500 ping for a minute or two. There are 13 wireless devices in my house but no more then 4 are on at a time (laptop, iphone, ipad, android). Youtube and netflix are non-existent in my house.

I would like this resolved please and thank you ahead of time

I would like to help but I would have to guess. The reason is nobody has MPBS. You have it wrong. It's MBps or Mbps. But you have cable internet so what you probably have is Mbps so lets take 35 as what you are paying for. So your top download speed is going to be 4.3 MBps or 4300 KB/sec. This is top and nobody gets top.Often you downloading of a file is determined by the place you are downloading from so trying from a few different places is a must. It can vary greatly.Ping is the time it takes for a signal to go from your computer to another and back.A difference of 25 isn't much and would not affect your download speed. If after trying different servers locations at different times so you can rule out heavy internet traffic and servers then you might want to contact charter. There isn't much you can do but switch out your modem. My guess is that's not going to help much but could if yours is going out.

Best thing to do is call your ISP.
