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. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1506189 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.
