Internet connection speed random slowdown
 
I have an 8Mbit/sec (nominal) Internet connection speed to a router (Netgear), a wired
connection to my desktop and a wireless link to my 2 laptops, one of which has a fixed LAN
IP address.
Normally, I get a good speed that hovers around 7Mbit/sec, but randomly it decreases to a
ridiculous value of 1-1.5-2 Mbit7sec., with a ping time of almost 400msec to a server that
is less than 20 miles away.
I have run AVG scan, no viruses were found, I constantly update and run both AdAware and
Spybot, but the problem persists. I am getting very frustrated. Any clues to what might
cause this misbehavior ?
Thanks in advance.

Mike

Hi
The whole Internet is Not on the server that is 20 miles away, that is only
the first Server in a chain of many depending on where you are going.
You can try to install this free program, http://www.d3tr.de/download.html
The following Screenshot is taken by using the List feature of 3DTrace as a
list.
http://www.ezlan.net/network/trace.jpg
The table shows the result of multi ping from my computer through a Buffalo
Router to Internet site 96.6.68.195*
The important columns in the table (for this discussion) are the two in the
middle. I.e. Min. ms and Max ms.
The numbers there show a typical outcome. As the trace progress on the
Internet the variation changes dramatically.
Run it when you have a slow down and you might find where the problem is
coming from.
