Aireplay-ng not working Still Not working

Hi

I started your course, and am enjoying it. I have reached as far as running deauth command, however first I had issues and kept getting “No Such BSSID available” then, i got “wlan0 is on channel 64, but the AP uses channel 44” even though i used the same command providing correct channel number. Finally i cam across one of your posts which says used “-D” option and it did manage to send the number of DeAuth commands, but that did nothing, so I tried the command while running airodump-ng as mentioned in your video, but still no luck

Can you please help
