Been having this problem lately in my last wi-fi cracking attemps, i have the RXQ, beacons, but no data, i check my injection test and the weird thing that sometimes it's says that injection its working, but two days till now it didn't show anything, checks 2 aps from close range and stops, don't show any significant info. Doing the standard procedure, airodump-ng to show de AP's, then i spoof with airodump-ng --bssid, wait a couple minutes to get enough beacons/data, meanwhile checking the wash for WPS, then i go for reaver/pixiewps, always worked well, but facing this problems lately.
Already tried changing MAC in case that it locked it and preventing me from injecting ivs. Using kali 2.0 with all updated tools.
