Aireplay-ng Hidden SSID deauth problem

[polyphemus]

Problem: unable to reveal hidden SSID

Steps Taken:
1. Airmon-ng to start up the monitoring interface
2. Started airodump-ng
---Ran into problem isolating the channel of the wireless AP
---had to first set the dump to scan all channels, then narroed it down to channel 5
Why does the dump show channel '-1'?
3. Once I now am capturing packets, I want deauth some clients, so they reconnect, revealing the SSID, and capturing the handshake
---Aireplay-ng deauth seems to need a beacon packet first but the problem is, a hidden SSID won't beacon out, how do I get around that?
---And I can't specify an ESSID because it's hidden...
---I checked, mon2 is fixed to channel 5 also and the dump is below:
---Also, for some reason all the Hidden SSID airodump shows has a power of '-1'
