Driver Installation - Microsoft Windows

TamoGraph is a tool for monitoring wireless 802.11 a/b/g/n/ac networks. To conduct passive surveys, you must have a compatible wireless adapter to use this product. In order to enable the monitoring features of your wireless adapter, you will need to use the special drivers that come with this product.

When TamoGraph is not running, your adapter will be able to communicate with other wireless hosts or APs, just like when you are using the original driver supplied by the adapter manufacturer. When TamoGraph is running, your adapter will be put in passive, promiscuous monitoring mode.

Prior to installing the new driver for your wireless adapter, be sure that your adapter is compatible with this product.  The list of compatible adapters can be found at the following URL:


For detailed, illustrated driver installation instructions, please launch the program and click Help => Driver Installation Guide in the program's menu.

If you use CommView for WiFi, another TamoSoft product, you do not need to install or change the driver, as TamoGraph and CommView for WiFi share the same drivers.

Driver Installation Troubleshooting on Windows

If you get the “Could not start device driver” or “Could not install device driver” message, first, make sure that the adapter is plugged in and verify that it is enabled by opening Control Panel => Network and Internet => Network Connections and right-clicking on the adapter icon.

The next step depends on the adapter chipset:

For adapters based on Atheros chipsets:

For adapters based on other chipsets (Intel, Dell, Broadcom):

Make sure that the special adapter driver was not replaced by a vendor-supplied driver. This may have happened when you ran Windows Update. Open Control Panel => System and Security, select the Hardware tab, and then open the Device Manager. Your adapter is listed under “Network adapters.” If the adapter name is not prepended with “[CommView],” then your adapter is not using the special driver for TamoGraph. In that case, click Help => Driver Installation Guide in the main application window and let the program reinstall the special driver.

Make sure that you use the latest driver supplied by your computer or adapter vendor. Visit the vendor's Web site to download and install the latest driver version.

If the problem persists even after rebooting, please contact our technical support.
