+### Important information
+```
+* With later kernels, it seems scanning (with "iw list") got issues, however, wifite2 scanning works fine..(weird!)
+* Setting monitor with the "iw" or "iwconfig" makes frame injection unstable, workaround: use "airmon-ng start <adapter>" for now
+
+Don't know what happened, but it could be kernels, iw update, network-manager.. needs some attention.
