    After 'restart' no available wifi connections, hard boot works fine?

    I am running 12.10 and the infamous rtl8723e - how ever I believe this is not driver related, once it's working it works fine with network-manager.

    If I shut down with the rtl8723e (working or not) in ubuntu, there is no issue once I boot back up. If I shut down or restart in windows (working or not), it works fine upon next boot.

    If the card is working and I 'restart' in ubuntu, the card loses functionality. Even if after 'restarting' if I choose Windows from grub, the problem persists in windows. The OS can see the card, but no networks are available, cannot force a connection or a scan.

    I did a lot of trouble shooting and searching, but I need some help.

    Re: After 'restart' no available wifi connections, hard boot works fine?

    I have tried both drivers that are available, I have also tried removing and adding the driver also restarting the service when the card is non-operational.

    Nothing I do seems to get a response from the card.

    Any idea guys? Is there a different script that runs when when you reboot vs shutdown?

    Fixed/Solved

    Like other issues with network-manager, Wicd seems to be the solution.

    Any idea how I can get Wicd to connect to a network on startup like nm can?

    It starts and auto connects when I log in, but I noticed there is no longer a remote login option, nor is the tray icon available.

    Looks like the 12.10 Remote Desktop @ login screen feature depends on network-manager, so it is installed again.

    Went back and set up wpa_supplicant and used wpa-roam in /etc/network/interfaces, no biggie there. This seems to prevent my 'restart' issue, as I am usually connecting to a known network.

    Wicd is nice, but I have no use for it I guess. If I need to scan and join a new network I can just use nm, then add it to wpa_supplicant with wpa_gui.
