    Re: How To: Manual Network Configuration without the need for Network Manager

    Greetings - noticed rt2860 driver referred to - does
    Code:
    dmesg | grep RT2
    show something like?:
    Code:
    [   35.973068] RtmpOSFileOpen(): Error 2 opening /etc/Wireless/RT2860STA/RT2860STA.dat
    [   35.973078] Open file "/etc/Wireless/RT2860STA/RT2860STA.dat" failed!

    [ 3697.880831] Read file "/etc/Wireless/RT2860STA/RT2860STA.dat" failed(errCode=0)!
    A RT2860STA.dat file must be created and Network Manager restarted using:
    Code:
    sudo su
    mkdir -p /etc/Wireless/RT2860STA
    touch /etc/Wireless/RT2860STA/RT2860STA.dat
    service network-manager restart
    exit
    OOB, out of the box, the UNR 10.04 Live CD is missing the file (ie. it is a bug)
    /etc/Wireless/RT2860STA/RT2860STA.dat which is required for the RT2860 driver as specified by the dmesg | grep RT messages.

    The given script creates the file (with null content) so the driver "works".

    ---------------------------------------------------------------------------------------------------------------------------------
    Another wrinkle (bug!) however is that it is exceedingly difficult to effect a connection with non-broadcasting SSID routers (the SSID is "hidden" but not the router service).

    While this thread is about alternate (manual) methods to Network Manager the following process in this post will use NM with some "manual" labour to coerce such connections, because NM's Connect to Hidden Wireless Network ... left click menu option is ineffective.

    Thus,
    Code:
    sudo iwconfig wlan0  essid  <hidden SSID> key s:<ASCII password string>
    is needed while toggling the Enable Wireless right click function of Network Manager to make the wireless connection and then selecting the now visible SSID from NM's wireless service drop down menu list.

    Code:
    sudo iwlist scan
    can be used for monitoring: when the router's ESSID:<hidden SSID> is seen instead of ESSID:"" then the router will be seen (eventually, in ~ 20 or 30 sec.) in NM's drop down menu at which point it can be selected.

    Is there a simple and short script to totally dispense with the need for NM? hmmm ... not this:
    Code:
    sudo su
    ifconfig wlan0 up
    dhclient -r wlan0
    iwconfig wlan0  mode Managed essid  <hidden  SSID> key s:<ASCII password string>
    dhclient wlan0
    exit

    I can add this information to the original post, however did this solution work for you?

    dmesg | grep RT2 doesn't give me any results. Any idea why?

    Re: How To: Manual Network Configuration without the need for Network Manager

    GREP, Global Regular Expression Parser, did not find the r.e. (regular expression) RT2 (which evaluates literally to an RT2 character sequence) in the kernel ring buffer as piped, |, from dmesg, display or driver message, which exposes the buffer.

    Presumably, dmesg by itself, does not fail, resulting in the revelation of the contents of the buffer where all the messages are without the character...s "RT2".
    (sorry about the missing D and the malapropism of your mal-appropriated character's name R2... R2D2 ~ RTD2 sorry - a little inside cybernetic humour from one cybernaut, to another)

    The RT2860 software suite of drivers and interface code is not required for the wireless hardware of all systems but when it is required, the posting 971 shows that the Lucid UNR 10.04 LTS Live CD often succumbs to the wireless failure as noted.

    The Belkin N Wireless USB Adapter F5D8053 presents a moving target for driver identificaton unless the exact version is known - caveat 1 below.
    Do
    Code:
    lsusb | grep Belkin
    If this does not show a version use Belkin's method.

    ============================== Caveat ================================
    A cursory survey of anecdotal documentation for the Belkin N Wireless USB Adapter F5D8053 implies that as in 967
    Code:
     sudo lsmod | grep rt28*
     rt2860sta             481561  0 
     rt2870sta             461811  0
    does list modules correctly as required.
    ================================================== =================
    The above may be incorrect.
    Closer scrutiny now reveals the following observations:


    1. Belkin's website µsoft (aka mu ~ micro ...) support software is F5D8053 hardware version dependent (ref: Belkin driver link origin page) - implicating the possible Ubuntu complicity with these version complications as well.
      This is confirmed in this link:
      http://ubuntuforums.org/showthread.p...0486074&page=2
      (which confirms a suspicion that in fact the rt2800usb is in fact the correct driver at least for V3) and
      http://ubuntuforums.org/showthread.p...8055&t=1673151 where V6 of the F5D8053 uses a driver for Realtek and NOT Ralink hardware:
      Code:
      
      lsusb | grep Belkin
      Bus 001 Device 010: ID 050d:815f Belkin Components F5D8053 N Wireless  USB Adapter v6000 [Realtek RTL8192SU]
      modinfo r8192s_usb
      filename:       /lib/modules/2.6.32-21-generic/kernel/drivers/staging/rtl8192su/r8192s_usb.ko
      description:    Linux driver for Realtek RTL8192 USB WiFi cards
      ...
    2. The rt2870 identifies with USB wireless devices but unless there is also another PCI wireless device, the rt2860 is NOT relevant
      .
    3. Ralink Linux drivers exist with this specific one: RT2870USB(RT2870/RT2770 as the only RT28xx qualified w/ USB thus presumably distinct from any other RT2870 or RT28xx listed
      .
    4. The Ralink site has no matching RT2800 (or even RT280x) listing but UNR 10.04 does! Note that it identifies with the rt2870 firmware!
      Code:
      modinfo rt2800usb
      filename:       /lib/modules/2.6.32-21-generic/kernel/drivers/net/wireless/rt2x00/rt2800usb.ko
      license:        GPL
      firmware:       rt2870.bin
      description:    Ralink RT2800 USB Wireless LAN driver.
      version:        2.3.0
      author:         http://rt2x00.serialmonkey.com
      ...
    5. The Ralink site has distinct RT3070 and RT2870 listings but UNR 10.04 identifies them similarly:
      Code:
      modinfo rt2870sta
      filename:       /lib/modules/2.6.32-21-generic/kernel/drivers/staging/rt2870/rt2870sta.ko
      alias:          rt3070sta
      version:        2.0.1.0
      license:        GPL
      description:    RTxx70 Wireless LAN Linux Driver
      ...

    Possible remedial actions:

    1. For Ubuntu 9.10 (karmic), this link http://ubuntuforums.org/showthread.php?t=1382798 details the manually labour intensive installation process which is explained in this link http://ubuntuforums.org/showthread.p...5837&p=9503272 .

    ================================================== =================

    1. Specific to your case 965, check
      Code:
       dmesg | grep rt2
      (note that RT is now rt) for any other driver messages.
      .
    2. Assuming there is nothing extraordinary ...
      Check ifconfig (interface configuration) to see if wlan0 is resident, it is on and confirm it is available
      Code:
      ifconfig -a
      sudo ifconfig wlan0 up
      ifconfig
    3. Assuming that wlan0 is now on and has a HWaddr: 94:44:52:44:0f:cf from the previous step ...
      Check the interface of the wireless configuration
      Code:
      iwconfig
      which, particularly this, should look similar to:
      Code:
      wlan0     RT2860 Wireless  ESSID:""  Nickname:"RT2860STA"
                 Mode:Auto  Frequency=2.412 GHz  Access Point: Not-Associated   
                Bit Rate:1 Mb/s   
                RTS thr:off   Fragment thr:off
                Link Quality=100/100  Signal level:-49 dBm  Noise level:-115 dBm
                Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
                Tx excessive retries:0  Invalid misc:0   Missed beacon:0
      See ref: Re: Wireless disabled for other samples of output from this command with explanations.
      .
    4. If so, the wireless adapter is functioning and can be tested by using it to list the available proximal wireless services with:
      Code:
      sudo iwlist scan

    For convenience of execution and brevity these commands are coalesced here, with a final dmesg check:
    Code:
    dmesg | grep rt2
    ifconfig -a
    sudo ifconfig wlan0 up
    ifconfig
    iwconfig
    sudo iwlist scan
    dmesg | grep RT2
    Note: except for sudo ifconfig wlan0 up, which enables the hardware, these commands, as used here, are all passive and simply report the status of the operating environment.

    Re: How To: Manual Network Configuration without the need for Network Manager

    Everything looks ok so far, what does lshw -C network list (this won't help if this is a usb device however).

    I don't have a rt device that uses this driver so hence I can't be of much help -- sorry!

    Re: How To: Manual Network Configuration without the need for Network Manager

    An excellent official refernce is the Debian Wifi USB Devices documentation.
    Check
    Code:
    lsusb | grep Belkin
    for V#
    If this does not show a version (& more importantly "Ralink RT2870"," Realtek RTL8192SU" etc.) use Belkin's method.

    ie. (there seems to be no V2 - drivers colours: no modinfo in 10.04 : driver exists in 10.04 but may need manual persuasion to correct functionality)
    V5 works w/ Realtek driver r8192u_usb details: debian.org page r8192u_usb
    V6 works w/ Realtek driver r8192s_usb ( debian.org's r8192s_usb ) or r8712u ( debian.org's r8712u )
    V1/3/4 works w/ Ralink drivers rt2800usb (endorsed in debian.org's rt2800usb ) or rt2870sta ( debian.org's rt2870sta )

    refs:

    http://ubuntuforums.org/showpost.php...4&postcount=15

    ================================================== ======
    ifconfig -a shows wlan0 is not bound (because it's missing) to a driver - the drivers rt28xx are loaded but not bound to the Belkin USB either because a different driver is needed or the drivers need repairing.

    PS. the rt2860sta is for a PCI card and is totally irrelevant, unless there is another wireless interface that is a PCI card

    (some) mutually exclusive possibilities are:

    rt2870sta if needed the supplied one is probably incorrect - it can be rebuilt ... painfully

    ** r8192s_usb **

    Best ** bet ** if Belkin USB wireless is a recent acquisition, V6 is the latest version.

    If it is V6 install and test via:
