I have recently purchased a Alfa Network AWUS036H and a 9 dBi antenna, the signal is great compared to my previous Linksys WUSB54G v4 but unfortunately it does not appear to be able to "Inject" / "Generate Packets" on the remote network (My netgear router)

In the past with my Linksys I have followed this tutorial:

But unfortunately I'm having a problem when I reach this part

If this command is successful we will now generate many packets on the target network so that we can crack the KEY. Type:
airplay-ng -3 -b [bssid] -h 00:11:22:33:44:66 [device]
It simply does not generate any packets, the "Data" does not increase at all, I have tried again and again, even sitting next to the router but it still does not work, are there any problems with this adapter and generating packets?
