network check tool

Is there any tool to check network performance, ie cables, cards etc.
Better if free.

My problem:

Supposedly I am connected with a 1.2 adsl line, but lately is very very slow.
When I ping from one machine to another and back, including the server it looks fine (the longest about 50 ms)
same from machine or server to the router (cisco) managed by the telecom company
but when I ping the IP on the other side of the router the ping time ranges from 2-300 ms to 2-3000 ms

Line tests from mcafee, broadband and alike give me poor performance results (around 2-300 mb)

Now I ain't a tech guy, much less a network one, but based on logic I would say the problem lies after the router, not my LAN to be clear. Am I right?
Because the telecom keeps telling me everything is fine from their view, and I should check my LAN, physically, meaning the cables and/or card and machines.

Although I do think is their fault I don't want to let anything unchecked, so any suggestion is welcome.

Thank you

Do a pathping. That will pinpoint where the problem area is. Pathping is provided with W2k.

We’d all like to think our company’s data is well protected, but when you ask IT professionals they admit the data probably is not as safe as it could be.

Ping plotter is a good one to find low performance nodes along the route:

But to check your speed you will still need IP-test from:

Pathping xxx.xxx.xxx.xxx
Open a command prompt and type the command. You will want to use the IP on the other side of the router.

Please explain the differences on the above

Additional info for you
I installed NetIQ (suggested bu PeteLong) on 2 machines
and on tcp udp testing from one machine to another it gives me times of about 2 ms, and a throuput of
18 MB for UDP and 28 MB for TCP

Using the TPtest (suggested by SNilsson) from server
TCP max send speed 101 Kbit/s
TCP max recieve speed 375 Kbit/s
UDP max send speed 136 Kbit/s
UDP max recieve speed 664 Kbit/s
available bandwith
TCP/UDP send 73% recieve 56%

I will raise the points, thank you

Looks like your router is dropping ICMP packets.

Thank you all

After all it wasn't my LAN, but the telecom company's fault, they've fixed it ... hopefully it'll stay that way.
