[X] ERROR: Failed to compile packet filter

I'm using Kali Linux 2 and I have an alfa AWUS036H USB wireless card.
What should I do to fix this problem?
thanks in advance.

Hi,

Just tested AWUS036H in Kali 2.0...plug-n-play pretty much.
Everything runs fine if you remember to

airmon-ng check kill

airmon-ng start wlan1

Then try running wash.
