    Re: How To: Troubleshoot your Wireless Network Connection - Connecting at Command Li

    How would you want me to organize it? It's an exact copy/paste of the terminal, except I edited the username. Tell me what to change please.

    I think he meant kevdog's post, but it's been reported and is all gone now.

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

    thanks kevdog - this was the final step in a quite a bit of effort to get a ZyXEL M-102 PCMCIA wireless card running on an old thinkpad 600X with hardy.
    For the record, this has an Atheros AR5513 chip (which is equivalent apparently to a AR5005VA). Eventually what is working is using ndiswrapper 1.53 and version 2.0.0 of the windows driver from zyxel. I can't describe exactly what is required - I've tried so many combinations, but it is possible!

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

    Here are some things you might want to try:
    1. Try
      Code:
      sudo /etc/init.d/networking restart
    2. Type
      Code:
      iwlist scan
      This should report all the routers that your wireless adapter can see. Make sure your router's ESSID and Address are present. You should be able to see your router even if you can't yet obtain a DHCP lease.
      • If you can't see your router using the "iwlist scan" command, then at least you'll know that this is the primary problem (not having to do with leases). Try moving the adapter, the router, or stuff in between so that there is less dense matter along the straight-line path between the two. Moving them closer together may also help.
      • If you can see your router:
        1. Connect a computer to the router, perhaps by ethernet cable. Open a browser to 192.168.1.1 (or whatever the address of your router is).
          Look through the configuration options, pay particular attention to anything having to do with DHCP. Make sure it is enabled, and that there is a range of IP addresses from which the router to assign.
        2. Make sure the router is not doing MAC filtering (at least until you get the connection working).
        3. Try powering-off then powering-on the machine instead of doing a soft reboot. This may reset the wireless adapter to a good state that is not achieved by a soft reboot.
    3. If none of the above helps, you might want to try going for a static connection. If you are using Network Manager, then one way to do it is to edit your /etc/network/interfaces file:
      Code:
      gksu gedit /etc/network/interfaces
      Edit the wlan0 section to look something like this:
      Code:
      auto wlan0
      iface wlan0 inet static
      address 192.168.1.46     
      netmask 255.255.255.0
      gateway 192.168.1.1
      • "gateway" should be your router's IP address.
      • "netmask 255.255.255.0" means that your computer should consider addresses of the form 192.168.1.xxx are part of its local network.
      • "address" should be of the form 192.168.1.xxx (assuming your gateway address starts with 192.168.1). xxx can be any number between 0 and 255.


      Power down, power up, and hopefully you'll then have a static connection. If not, try
      Code:
      sudo /etc/init.d/networking restart

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

    Thanks for the ideas, i'll try them, but i know the problem isn't with the modem or router, because we have 3 other computers on the network.

    I just recently decided i wanted to try Linux, and of course dumb me didn't even think about partitioning for a dual boot, and they don't even make the drivers for this computer any more, so there's no option of going back to windows until i get a new computer, so i'm hoping i can get the hang of this lol.

    i'll report back after i try your suggestions if i'm still having trouble.

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

    Hopefully someone in here can help me with my problem. My wireless work out of box, meaning I do not set anything but just use Network Manager to establish connection. However, I must enter ESSID and WPA password and disable broadcasting everytime I want to re-connect wirelessly (mostly I use ethernet connection). I can not broadcast ESSID to enable wireless connection. Another thing is pertaining to conky. After I dis-connect my wireless connection, ESSID will still displayed in conky. As a matter of fact, it will only be cleared if I log out or restart.

    Before I follow the first post, I would like to know whether my problem is related to it (first post)? Hope someone can assist me

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

    ok, i had this working once for about 3 days and then it quit working and i was trying to do it again, as seeing i didn't put it in the rc.local and when i get to "sudo dhclient -r wlan" it says:

    ...listening on LPF/wlan0/00:19:7e:5f:d7:b5
    sending on LPF/wlan0/00:19:7e:5f:d7:b5
    sending on Socket/fallback
    DHCPRELEASE on wlan0 to 192.168.1.1 port 67
    send_packet: Network is unreachable
    send_packet: please consult README file regarding broadcast address.

    then i just noticed that the instead of saying stephen@... it said "sstephen@..." then i hit enter and it when back to normal.

    any help here would be great thanks in advance

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

    I keep getting "Unsupported driver 'ndiswrapper=wext'" whenever I type the following command:

    sudo wpa_supplicant -w -D ndiswrapper=wext -i wlan0 -c /etc/wpa_supplicant.conf

    I've tried several different combinations, but I obviously am not typing the driver name correctly. Below is the results of running:

    sudo lshw -C network

    My networks are claimed, my driver is installed correctly, and I can see available wireless networks in my area, but I just can't get the stupid thing to connect, so I'm going through this manually.

    My system:

    Release 8.04 (hardy)
    Kernel Linux 2.6.24-19
    GNOME 2.22.3

    Intel(R) Pentium(R) 4 CPU 1500MHZ

    This only started happening after my upgrade from 7.10. Before that my wireless card was working just fine. I removed the driver and reinstalled after the upgrade, but that did not help either.

    Thanks for any help you can offer.
