Same here. My wireless was working in 8.10 with router set up to hidden SSID, WPA2 Personal, TKIP & AES. Now I can only connect to WLAN if the router is set up to broadcast SSID.
When SSID is broadcasted, I get the following in my wpa_supplicant.log CTRL-EVENT-SCAN-RESULTS Trying to associate with 00:21:91:d4:14:bd (SSID='martian' freq=2412 MHz) CTRL-EVENT-SCAN-RESULTS Associated with 00:21:91:d4:14:bd WPA: Key negotiation completed with 00:21:91:d4:14:bd [PTK=CCMP GTK=TKIP] CTRL-EVENT-CONNECTED - Connection to 00:21:91:d4:14:bd completed (auth) [id=0 id_str=] If I tell the router to stop broadcasting SSID then I get the following line CTRL-EVENT-DISCONNECTED - Disconnect event - remove keys and the connection is dropped. After that there is no way to connect to wireless, and after first unsuccessful attempt the Network Manager simply stops trying and does nothing in response to try to connect to hidden network. wpa_supplicant.log file is being filled will the "CTRL-EVENT-SCAN- RESULTS" lines. Same events reflected in syslog: 1. While SSID is being broadcasted May 11 13:20:08 mars kernel: [ 271.356066] wlan0: authenticate with AP 00:16:ca:f5:31:41 May 11 13:20:08 mars kernel: [ 271.507094] wlan0: authenticated May 11 13:20:08 mars kernel: [ 271.507108] wlan0: associate with AP 00:16:ca:f5:31:41 May 11 13:20:08 mars kernel: [ 271.525979] wlan0: RX AssocResp from 00:16:ca:f5:31:41 (capab=0x421 status=0 aid=2) May 11 13:20:08 mars kernel: [ 271.525989] wlan0: associated 2.

Attepts to connect to now hidden network with Network Manager produce the following syslog entries: May 11 18:36:50 mars NetworkManager: <info> Activation (wlan0/wireless): connection 'martian' has security, and secrets exist. No new secrets needed. May 11 18:36:50 mars NetworkManager: <info> Activation (wlan0) Stage 2 of 5 (Device Configure) complete.

To date, I cannot establish connection to hidden wireless network. Please let me know if I can be of any further assistance to fix this nasty bug.
