My usb card is Tplink TL-WN722N and my kali linux is 1.0.9 x64 VM setup.
When I try to setup the Access point through airbase-ng, the access point will appear and just can be maintained about a min than disappear. Even though the access point cant be detected by my devices, the strange thing is that I can see the access point in the list of airodump-ng but with 0 PWR. How can I solve this problem? thank you very much (plx forgive my bad English I am not the native Englsih speaker )
My steps for setting up the access point
1.
ifconfig wlan0 down
iwconfig wlan0 mode monitor
ifconfig wlan0 up
airbase-ng -e roy wlan0
05:07:23 Created tap interface at0
05:07:23 Trying to set MTU on at0 to 1500
05:07:23 Access Point with BSSID C0:4A:00:29:D1:DA started.
the access point will disappear from my wifi list of my host computer around a min, than I try to use airodump to see whether I can find the access point
2.
airodump-ng wlan0

I dont know why the PWR will be 0 , moreover the channel of the access point will keeping changing( C0:4A:00:29:D1:DA 0(PWR) 14 0 0 7 54 OPN roy )
