I'm running Fedora 18 on a Toshiba laptop with the notorious RTL8723 wireless card. I've been able to compile the driver using lwfinger's instructions from this forum thread herewget http://linuxwireless.org/download/compat-wireless-2.6/compat-wireless-2012-10-03.tar.bz2wget http://www.lwfinger.com/realtek_drivers/rtl8723ae_master_patchtar jxvf compat-wireless-2012-10-03.tar.bz2cd compat-wireless-2012-10-03/patch -p1 < ../rtl8723ae_master_patchmakesudo make installsudo modprobe -v rtl8723aeAfter performing these steps the device can indeed see the available wireless networks. The problem appears when I actually try to connect to one of the WPA2-secured ones -- the Gnome network manager keeps asking me for authentication and refuses to establish the connection. I take it I should now figure out whether this is a driver issue or a network manager issue (or something else) but I'm not sure how to proceed.  EDIT: It appears that the problem isn't with the network manager after all: after disabling Network Manager I tried running wpa_supplicant from the terminal, and all I got in response were the following messages, which just kept coming:wlan0: Trying to associate with 7c:4f:b5:8e:a0:87 (SSID='mynetwork' freq=2462 MHz)ioctl[SIOCSIWFREQ]: Device or resource busywlan0: Association request to the driver failedwlan0: Associated with 7c:4f:b5:8e:a0:87wlan0: Authentication with 7c:4f:b5:8e:a0:87 timed out.wlan0: CTRL-EVENT-DISCONNECTED bssid=00:00:00:00:00:00 reason=0wlan0: Trying to associate with 7c:4f:b5:8e:a0:87 (SSID='mynetwork' freq=2462 MHz)ioctl[SIOCSIWFREQ]: Device or resource busywlan0: Association request to the driver failedwlan0: Associated with 7c:4f:b5:8e:a0:87
