http://www.testmy.net/forum/index.php?topic=11588.0  We do not own a heatpump

http://www.[this.site.has.been.blocked.for.spamming]/read_articles.php?id=1885 I do not have a router

http://www.[this.site.has.been.blocked.for.spamming]/read_articles.php?id=117 PC Subwoofer off during tests and I do notown a cable modem. It is DSL.

Something at your end (receiver) is limiting speed. This can be seen by the RTT value of 1195 ms. Under normal conditions, RTT (round trip time) should not exceed 300 ms if you are in USA.
I called Verizon to do a line check 3 weeks ago and line check came back clean.

Any other electrical devices near your comp that emits EMI? A subwoofer has a hugh magnet within its casing. Even with power off, there is still magnetic effect. Keep it away from your modem and signal cables. Any other devices like cordless phone etc.?

No other devices what so ever. I just moved my modem from above my sub wolfer to down under my desk. I'll run the test again and post results of site you wanted details on and my http://www.dslreports.com line test results as well.

Your PC is connected to a Cable/DSL modem
Information: The receive buffer should be 445.80 Kbytes to maximize throughput

========================
   ------  Web100 Detailed Analysis  ------
Cable modem/DSL/T1 link found.
Link set to Full Duplex mode
No network congestion discovered.
Good network cable(s) found
Normal duplex operation found.

Web100 reports the Round trip time = 1217.35 msec; the Packet size = 1460 Bytes; and
No packet loss was observed.
This connection is receiver limited 86.04% of the time.
  Increasing the the client's receive buffer (125.0 KB) will improve performance
This connection is network limited 13.93% of the time.

Web100 reports TCP negotiated the optional Performance Settings to:
RFC 2018 Selective Acknowledgment: ON
RFC 896 Nagle Algorithm: ON
RFC 3168 Explicit Congestion Notification: OFF
RFC 1323 Time Stamping: OFF
RFC 1323 Window Scaling: ON
Packet size is preserved End-to-End
Server IP addresses are preserved End-to-End
Client IP addresses are preserved End-to-End

Checking for congestion
   (cwndtime > .02) [0.13>.02], (mismatch = 0) [0=0]
   (MaxSsthresh > 0) [0>0]

estimate = 9.15 based on packet size = 11Kbits, RTT = 1217.35msec, and loss = 1.0E-6
The theoretical network limit is 9.15 Mbps
The NDT server has a 8192.0 KByte buffer which limits the throughput to 52.57 Mbps
Your PC/Workstation has a 125.0 KByte buffer which limits the throughput to 0.80 Mbps
The network based flow control limits the throughput to 0.81 Mbps

Your RTT is still too high. This usually means something is limiting a clear signal flow. Can be a line quality problem or a faulty cable, or effects on your signalling devices (modem/router). If you are running a wireless, then it may be a problem with signal transmission to your router.

Please do some troubleshooting. When RTT goes down, PC throughput limit will go up and so does your download speed.

Here is a link that may help you to located possible line problem:

Thanks for all the help but if it has come down to changing a wire or moving my stuff around for a clear signal flow......... I'm thinking it is not going to jump that high. A lot of trial and no change. Oh well, trogers you really went out of your way to help me and as I said, nothing has worked. Oh well, wonder if cable would be a better alternative for same $.
Thanks anyway but chalk this one to a lost cause.
