Normally you should get lot of corrupted packets from surrounding transmission. In my case, monitor mode hangs sometime and I don't get any packets. Then if I delete the interface and create a new interface using the iw command I gave earlier, I get packets with crc error. You can also modify already created interface using iw wlan0 set monitor flag fcsfail Musa
