Can't Get a Station with WEP

These are the following commands I have done.

ifconfig wlan1 down

iwconfig wlan1 mode monitor

ifconfig wlan1 up

airodump-ng wlan1 <- This does show all APs in range

airodump-ng --bssid -c 4 -w filename wlan1 <- This is where my issue is

aireplay-ng -3 -a -h wlan1 <- haven't run this command yet because previous one doesn't work

My issue on the noted command is that it doesn't show any stations when I have a phone connected to it with data being transferred. As always thank you in advance!
