[SOLVED] Network Manager cannot connect to wifi after suspend

Hi,
There appears to be similar threads recently, but they relate to no wifi at all. I did some updates today, and now if I suspend or hibernate, network manager cannot reconnect to my wifi. It will (after a while) ask me to authenticate, but still fails. Nothing works except a reboot where it connects without issue.
It was fine yesterday, has only started today. Here is my pacman log for today's updates:

For those using the arch repo kernel the next release will solve this issue. So I suggest waiting for this (no more than a few days) and use the LTS kernel in the meantime (or using a fixed ath9k module if already built).
Thanks for that heiko. I thought that would be the case, hence I just waited.
Will mark this as solved.
Cheers.

  • Cannot connect to Wifi after downloading windows 10

    I just downloaded Window 10 and now I cannot connect to my wifi. Can anyone help understand why. I need it asap. Thanks

    Twice I have upgraded to Windows 10 in the last two days but each time after I cannot connect to my home wifi or indeed any wifi.I have tried updating drivers, changing router channel before giving up and rolling back to Windows &.Obviously I would like to upgrade but it's proving very difficult with my limited tech knowledge on the inner workings of the laptop though I am very good at following step by step instructions.The problem is that once I have upgraded I cannot do anything because I have no internet to search for possible solutions.Is there anyone who can help me sort this out and anything I need to do before upgrading again.The wifi will connect to my home router but it shows as LIMITED and there is no internet access.I would be grateful for any help.Thank you. Just to add, I am on Virgin broadband with a download of 95Mb. Connected by Ethernet or by wifi give the same limited error.

  • [SOLVED]Network Manager Applet and nmcli failing after GCC upgrade

    Hi All,
    So I went to update my system today and there were only like 8 or 9 updates. Like many other people I had an issue with gcc and pacman. To fix this I ran
    pacman -S gcc
    Then I ran:
    pacman -Su
    which updated pacman itself. On reboot though I noticed network manager applet was unable to find any of my network devices despite the fact that network manager was running and I had an IP address. I killed nm-applet and re-ran it and it spewed errors about not being able to connect to network manager. I tried running nmcli and it did the same thing. However, when I run nmcli as root it works. Looking at the arch wiki they suggest you be a part of the wheel and network group which I made sure I was. Everything was working up until I ran those two updates though. Anyone else have this happen or have any idea what is wrong?
    Thanks,
    Hemmar
    EDIT: Never mind - a patch was released for consolekit which fixes the problem.

    Hi guz46
    I have already tried removing the ! and the same thing happened ... but I realised today that I was being automatically connected to "Auto eth0" despite there being no cable present. When automatic connection was disabled on "Auto eth0" my 3G connection (ppp0) connected fine.
    Could you clarify that the preferred set-up in the /etc/rc.conf for the interfaces is without the !. The Wiki for networkmanager says to disable them, but then states that some may need to be reenabled with no explanation. The purpose of this confuses me!
    Thanks for you help anyways,
    Scott
    EDIT:
    I appear to have fixed my problem with the auto connection on the various interfaces by updating my /etc/rc.conf file to:
    #Static IP example
    #eth0="dhcp"
    ppp0="dhcp"
    wlan0="dhcp"
    eth0="dhcp"
    INTERFACES=(ppp0 wlan0 eth0)
    Thus ensuring that I can connect in order of preference.

  • "Configuration Manager cannot connect to the site" after site update from SP1 to R2

    Our dev SCCM environment only has a single primary site with a remote SQL database.  Initially, the dev primary site had SP1 Beta (5.00.7782.1000) installed but as everyone is aware there is no upgrade path available to SP1 or R2 from Beta; so, we uninstalled
    the site and removed the database, re-installed SP1 non-Beta (5.00.7804.1000), then proceeded to update all devices with the latest client agent.  Afterwards, we attempted to upgrade the site from SP1 non-Beta (5.00.7804.1000) to R2 (5.00.7958.1000).
     All seemed well until we attempt to open the Configuration Manager console and we get the following error message:
    Configuration Manager cannot connect to the site (Site Name)
    The Configuration Manager Administrator console could not connect to the Configuration Manager site database. Verify the version of the console is compatible with the version of the site server you are connecting to and then try to connect again.
    So we tried reinstalling the console directly from here...
    "C:\Program Files\Microsoft Configuration Manager\tools\ConsoleSetup\AdminConsole.msi"
    still the same error message persisted, so we tried installing it from here...
    "C:\Program Files\Microsoft Configuration Manager\tools\ConsoleSetup\ConsoleSetup.exe"
    still the same error message persisted, so then we tried installing it directly from the R2 (5.00.7958.1000) installation media, and afterwards the same error message persisted....
    All along, we were checking the AdminConsole log from here:
    "C:\Program Files (x86)\Microsoft Configuration Manager\AdminConsole\AdminUILog\SmsAdminUI.log"
    Here are the contents:
    [4, PID:4836][04/22/2014 15:21:10] :Property: 'Features'\r\nSystem.Management.ManagementException\r\nNot found \r\n   at System.Management.ManagementException.ThrowWithExtendedInfo(ManagementStatus errorCode)

    connection)
       at Microsoft.ConfigurationManagement.AdminConsole.SmsSiteConnectionNode.GetConnectionManagerInstance(String connectionManagerInstance)\r\nNo details are available for this error.\r\n
    Once again, we validated we could connect to the SQL database from this box, and that the console was at the same version as the site.  Any help or guidance with getting our access to the console restored after the SP1 to R2 upgrade would be greatly
    appreciated. 

    From the Primary Site Server, I tried uninstalling the Admin Console and re-installing using:
    consolesetup.exe /q TargetDir="%ProgramFiles%\Microsoft Configuration Manager" EnableSQM=0 DefaultSiteServerName=<SiteServerName>
    Of course replacing <SiteServerName> with the FQDN of my Primary Site Server.  Console installed successfully however the same error message persists.
    Also tried installing the console on a clean Windows Server 2008 R2 installation.  I tried it from the R2 (5.00.7958.1000) installation media, from the "C:\Program Files\Microsoft Configuration Manager\tools\ConsoleSetup\" both without any luck, the
    same error message persists.  I verified I could ping the FQDN of the site server also, and that the firewall between the two permits communication over the ports listed here: http://technet.microsoft.com/en-us/library/hh427328.aspx
    Any help would be greatly appreciated.

    Some things to try first:
    1. Turn Off your iPad. Then turn Off (disconnect power cord for 30 seconds or longer) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
    2. Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
    3. Change the channel on your wireless router (Auto or Channel 6 is best). Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
    4. Go into your router security settings and change from WEP to WPA with AES.
    5.  Renew IP Address: (especially if you are droping internet connection)
        •    Launch Settings app
        •    Tap on Wi-Fi
        •    Tap on the blue arrow of the Wi-Fi network that you connect to from the list
        •    In the window that opens, tap on the Renew Lease button

    Welcome to the Apple Community.
    Intermittent problems are often a result of interference. Interference can be caused by other networks in the neighbourhood or from household electrical items.
    You can download and install iStumbler (NetStumbler for windows users) to help you see which channels are used by neighbouring networks so that you can avoid them, but iStumbler will not see household items.
    Refer to your router manual for instructions on changing your wifi channel or adjusting your multicast rate.
    There are other types of problems that can affect networks, but this is by far the most common, hence worth mentioning first. Networks that have inherent issues can be seen to work differently with different versions of the same software. You might also try moving the Apple TV away from other electrical equipment.
