As of lately, I've been having serious issues with my bandwidth dropping to near nothing when I try to stream a video or download. It'll do the short burst (around the advertised 10mbps download) then it'll drop down to around 200kbps and hold there. After which, my ping will hang in the thousands and continue to do this until I either reset my modem or wait a good five or ten minutes for it to stabilize.
1. What is your advertised internet speed ? 10mbps down, 0.8mbps up
2. What actual transfer speed do you get? Unknown, periodically drops and becomes unstable.
3. Who is your Internet Provider (ISP), and what type of connection do you have ? i.e. Centurylink DSL
4. What are your current settings ? do a TCP/IP Analyzer test and copy/paste the results in your post. (Posted below)
5. Your modem/router/ap brand ? ZyXEL PK5001z
6. Your Operating System ? Windows 7

Bandwidth issues
It is normal for latency to spike up and your connection to become unresponsive if most of your available bandwidth is used up. This can somehow be mitigated if using QoS/WMM at your router. It is also normal for transfers to start higher, and then settle down to your actual speed.
What do you get at speedtest.net ?
What is connected to your DSL modem, do you have a wireless router, how is your client connected ? (wifi or wired)
It is likely that your actual speed provided by your ISP is much less than 10Mbps, and you're simply filling up all usable bandwidth. A traceroute, and a speedtest during peak times may help make the case to your ISP about checking your line.
