I caught the an unexpected disconnect event behavior and this is the
iwconfig info:

iwconfig
eth0      no wireless extensions.

wlan0     IEEE 802.11bgn  ESSID:off/any  
          Mode:Managed  Access Point: Not-Associated   Tx-Power=20 dBm   
          Retry short limit:7   RTS thr:off   Fragment thr:off
          Power Management:off
          
lo        no wireless extensions.

Reconnection in this case was successful after a manual selection of the
SSID again. This manual reconnection process is not always successful
with every disconnect event.

Upon reconnecting the iwconfig shows:
iwconfig
eth0      no wireless extensions.

wlan0     IEEE 802.11bgn  ESSID:"umd-secure"  
          Mode:Managed  Frequency:2.412 GHz  Access Point: 18:9C:5D:EF:CB:C2   
          Bit Rate=7.2 Mb/s   Tx-Power=19 dBm   
          Retry short limit:7   RTS thr:off   Fragment thr:off
          Power Management:on
          Link Quality=32/70  Signal level=-78 dBm  
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:398  Invalid misc:392   Missed beacon:0

lo        no wireless extensions.

Title:
  1814:3290 HP ENVY 15Z-J100 NOTEBOOK PC wifi dropping connection

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  At various points on the University of Maryland College Park campus, I get an initial connection with the built in wifi card, but it will drop frequently and have difficulty reconnecting to this secured wifi. After the loss of connection I saw a repeated:
  ieee80211 phy0: rt2x00queue_flush_queue: Warning - Queue 2 failed to flush

  This doesn't happen off campus that I've found at this time. My
  Android Phone and Tablet do not have wifi issues connecting.
