Monitor DD-WRT bandwidth on your local computer

DD-WRT has bandwidth usage GUI interfaces built into the web interface when you are in your router.  What if you wanted a simple way to monitor bandwidth on your local computer?

You can use STG SNMP Monitor a small program on your local computer to monitor the bandwidth.

  • Access your DD-WRT router and enable SNMP under Services
  • Load STG on your computer (Runs without an installation.  You can save files for different routers)
  • Go to the Settings menu and change the IP address and OID numbers for DD-WRT

The OID numbers are :

1.3.6.1.2.1.2.2.1.10.8 download (green) 
1.3.6.1.2.1.2.2.1.16.8 upload(blue)
Make sure there are no spaces after the last numbers

Check bits per second – your max rate which is bytes per second max should be bits max. Convert it here.


Click OK and then go to file and save so you can quickly open the settings.

Now go to the Bandwidth Place and test your speed.  (This doesn’t increase speed, it monitors your bandwidth.)  By going to the Bandwidth Place, it will send data up and down which you should see on your SNMP monitor.

This will work with other routers if you enable SNMP and find the OID numbers for your routers.

One tweak overlooked tweak by most DD-Wrt users  – the most effective tweak is “Services – Services – WAN Traffic Counter – Disabled”.  How often do you look at traffic on the router.  Using SNMP monitoring on a computer saves your router’s CPU usage.
