Is there a way to benchmark how fast my router is connected to my PC, independent of the internet?

I've had slower-than-usual internet-based benchmarks, and I'm having a hard time figuring out if it's because of a bad router-to-PC connection (interference, bad signal, etc.) or if it's indeed because my internet is actually slower.

Is the connection wired or wireless from the PC to the router? –  Paul Dec 23 '11 at 8:18
    
@Paul: Wireless. –  Mehrdad Dec 23 '11 at 8:25
    
sourceforge.net/projects/iperf Cross-platform tool with great functionality. –  user203508 Mar 1 '13 at 23:02

In UNIX, you can use a utility called pv (pipe viewer) to measure data through a pipeline. You can hack this to test throughput to another host. Assuming you have ssh access to your router:

yes | pv | ssh router.foo.com "cat > /dev/null"

You're basically piping arbitrary data from the yes command to /dev/null on your router and measuring the throughput with pv.

There are a number of other ways to accomplish this, with a variety of tools. If you're on a Windows box, you can try hacking similar operations with Cygwin, but I'm sure others on this forum can provide solid suggestions on other applications.

SSH usually uses compression, so this is not the best way to measure it. –  Ernestas Dec 29 '12 at 9:10

If you have another PC in the same network, you can have a file transfer between those 2 PC's and see the network bandwidth usage via standard methods available.

The trouble is that PC-to-PC transfer is ridiculously slower than internet download anyway (no idea why), so this doesn't work. –  Mehrdad Dec 23 '11 at 9:37
    
@Mehrdad: are you serious?? How can that be??? You should edit the question with your wireless modem, and what all config options have you seected.. –  Vineet Menon Dec 24 '11 at 14:45

The Echo protocol and the spray programs were designed for this purpose.

But probably your router doesn't support this.

I think your looking for a LAN Speed Test. Here is a piece of free software that should do what you are after: Link. I found this with a Google search for LAN speed test. If it not what you need there are other options.
