The network is an 802.11n, but iwconfig displays 802.11g. My txpower was 40 something but I changed it to 15 as suggested with no change in results. (It actually shows 16 after the change, as opposed to 15)
    I can't confirm positively; however, this is the first such complaint I recall. If you change the router to WPA instead of WPA2 or WEP or open, does it connect seamlessly?

    Re: Netgear WNDA 3100 v2 wireless adapter -- How to install?

    I am trying to set this up on Ubuntu server 12.04 64bit to connect to a WPA2 secured network. Everything seems to work and I can connect to my SSID with the following command:

    sudo wpa_supplicant -B -iwlan0 -c/etc/wpa_supplicant.conf -Dwext
    Output from iwconfig shows I'm connected to my network "Legendary"

    Unfortunately I can't seem to get an IP address. I've tried using the dhclient command, but it just hangs and never gives me an IP. I don't think the router is the problem as every other device connects without problems to it.

    Here is the output of ifconfig, you can see I don't get an IPv4 address for wlan0:

    bmather9@bmather9:~$ ifconfig

    bmather9@bmather9:~$

    So what is my problem? I honestly don't know anything about network config in linux. I tried editing the /etc/network/interface file, but it didn't seem to do anything. I also tried to set a static IP address using this interface file, but nothing changed. Any help is greatly appreciated!

    Re: Netgear WNDA 3100 v2 wireless adapter -- How to install?

    Aren't you using Network Manager? It ought to do all this for you and without the terminal command:
    sudo wpa_supplicant -B -iwlan0 -c/etc/wpa_supplicant.conf -Dwext
    Moreover, NM is designed to disallow an IP address for wireless if you have one for ethernet, which you do:
    eth0 Link encap:Ethernet HWaddr b8:97:5a:06:d6:26
    inet addr:192.168.9.10 Bcast:192.168.9.255 Mask:255.255.255.0
    inet6 addr: fe80::ba97:5aff:fe06:d626/64 Scope:Link
    UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
    I suggest you detach the ethernet, click the NM icon and try to connect.

    Re: Netgear WNDA 3100 v2 wireless adapter -- How to install?

    It's a headless server so the gui is not installed. Can I still use network manager? I'll try to round up a keyboard and monitor so I can try to configure with the ethernet unplugged; I've been doing everything over ssh so far.

    Re: Netgear WNDA 3100 v2 wireless adapter -- How to install?

    Ahhh, a server. I suggest you amend /etc/network/interfaces to something like:
    Code:
    auto lo
    iface lo inet loopback
    
    #auto eth0
    iface eth0 inet dhcp
    
    auto wlan0
    iface wlan0 inet static
    address 192.168.0.87
    netmask 255.255.255.0
    gateway 192.168.0.1
    wpa-ssid your_ssid
    wpa-psk your_password
    dns-nameservers 8.8.8.8 8.8.4.4
    Then get the system to see the change:
    Code:
    sudo ifdown wlan0 && sudo ifup -v wlan0
    Assuming there are no errors, I'd think you could safely detach the ethernet and ssh to the wlan0 address.

    Re: Netgear WNDA 3100 v2 wireless adapter -- How to install?

    Code:
    Starting /sbin/wpa_supplicant...
    ioctl[SIOCSIWENCODEEXT]: Invalid argument
    ioctl[SIOCSIWENCODEEXT]: Invalid argument
    I am not yet sure it has much to do with the issue, but may we see:
    Code:
    cat /etc/wpa_supplicant.conf
    As always, please disguise the WPA key. Do verify, however, that it is correct in every respect and exactly matches that in the /etc/network/interfaces file.

    Re: Netgear WNDA 3100 v2 wireless adapter -- How to install?

    bmather9@bmather9:~$ cat /etc/wpa_supplicant.conf
    network={
    ssid="Legendary"
    psk="**********"
    }
    I originally had the psk in quotes and in hex, but have now changed it to normal ASCII characters still with quotes. Doesn't seem to affect anything either way when trying to bring up wlan0.

    My original attempt shown below also gives invalid arguments:

    bmather9@bmather9:~$ sudo wpa_supplicant -B -iwlan0 -c/etc/wpa_supplicant.conf -Dwext
    ioctl[SIOCSIWENCODEEXT]: Invalid argument

    What is here? It ought to be the key in clear text; that is, the exact key you put in the router. For example, if the key you put in the router's fill-in for the WPA key is ihatewarmbeer, then the interfaces file should be:
    # This file describes the network interfaces available on your system# and how to activate them. For more information, see interfaces(5).


    # The loopback network interface

    Yea, I have the WPA password in plain text (not hex) in the interfaces file. I double and triple checked it now.
