I was trying to de-authenticate the client on one of my personal wifi using aireplay-ng.
but it gave error:
root@HTCodersInc:/home/ht# aireplay-ng -0 1 -a 08:3E:8E:1F:10:B6 -e "balli ka network" mon0 00:35:19 Waiting for beacon frame (BSSID: 08:3E:8E:1F:10:B6) on channel -1 00:35:19 Couldn't determine current channel for mon0, you should either force the operation with --ignore-negative-one or apply a kernel patch
The Wifi was running on channel 11 and has WP2 encryption.
