# On some devices such as the Allegro 500 the WiFi device does not come up in USB3 mode if the device is already connected when powering the device up. Connect the device after the system is completely booted to get full USB3 speed. | # On some devices such as the Allegro 500/510 the WiFi device does not come up in USB3 mode if the device is already connected when powering the device up.

# The achievable speed of the WiFi decryption depends on the Allegro model. More powerful models can of course also achieve higher decryption speeds, but the model Allegro 200 does not have hardware decryption available and it is therefore limited in the amount of traffic to decrypt. | # The achievable speed of the WiFi decryption depends on the Allegro model.

# The reception is highly influenced by the location of antenna. Especially when advanced WiFi techniques like beam forming are used, it may happen that only parts (or even none) of the traffic is seen at the capture device. For better results, try to place the antenna as near as possible to the receiver or sender, or in between two devices of interest. <br>You can check the TCP stats about [[TCP module#Missed data|missed data]] to see if there is significant traffic not seen by the Allegro device. | # The reception is highly influenced by the location of antenna.
