Same problem using Atheros AR5413 802.11abg NIC (rev 1) Network manager hangs around until poked with iwpriv ath0 mode 3, or iwconfig ath0 essid MYSSID..
Alternative workaround is to set router to support g only. Since doing this NetworkManager connects automatically, BUT now knetworkmanager repeatedly reports that it has found a new network even though it is already connected. suspect this is something to do with bgscan??? This happens consistently regardless of whether the wireless SSID is hidden or not. kernel: 2.6.24-12-generic iwconfig ath0 ath0 IEEE 802.11g ESSID:"MYSID" Nickname:"" Mode:Managed Frequency:2.462 GHz Access Point: 00:AA:AA:AA:FF:FF Bit Rate:54 Mb/s Tx-Power:17 dBm Sensitivity=1/1 Retry:off RTS thr:off Fragment thr:off Power Management:off Link Quality=54/70 Signal level=-42 dBm Noise level=-96 dBm Rx invalid nwid:22169 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:0 Invalid misc:0 Missed beacon:0 lspci -v 02:03.0 Ethernet controller: Atheros Communications, Inc.
