11. Troubleshooting
If you encounter problems acquiring packets, then walk through the following checklist. If you don t
manage to solve the problem, feel free to contact ubisys support.

Make sure that the driver is properly installed

Make sure that you have disabled all networking protocols

Make sure that the ubisys 802.15.4 networking adapter is enabled and has not been disabled
by Windows network discovery algorithm

Make sure that no enterprise security software, firewall or anti-virus program blocks the network
adapter. Contact your IT department if you are uncertain. Some of these applications require
the IT administrator to authorize new hardware, in particular network adapters, before they are
allowed to operate normally

Make sure that there is actually wireless traffic on the channel that you have selected

If you are trying to capture data from a single transmitter, you might be in a dead-spot (unlikely,
but still)

Make sure that there is no interference that prevents the sniffer from receiving data

Unplug the USB stick and plug it in again, then restart packet acquisition
