LAWN Device Login

Certain devices may not have a web browser or may have limited or cumbersome means of inputing a username and password ( some game devices, mobile phones, and PDAs fall under this category) but you may still wish to utilize the LAWN. By using the LAWN Device Login feature, you may authenticate these devices so that they can communicate with the outside world. By doing so, you accept the same responsibility for that device as you would by utilizing a personal laptop on the LAWN.

Another option is to request LAWN Device Registration.

LAWN Device Login Requirements

You will need:

  • Go to https://auth.lawn.gatech.edu/
  • Your GT Account username and password
  • The MAC Address (sometimes also referred to as "Ethernet Address") of the device you wish to utilize. (Acceptable formats: 01:23:45:67:89:ab, 01-23-45-67-89-ab, 0123456789ab)
  • If the device utilizes wireless, it will need to be configured with the LAWN SSID and WEP key.
  • The device needs to be configured to utilize DHCP to obtain its IP Address and be online (it must have a valid DHCP lease).
  • LAWN Device Login Behavior

    Device Login

    Once you authenticate with your username and password, the system will query the DHCP server for a valid lease usi ng the MAC Address that you provide. If there is a valid DHCP lease, we then open a hole in the firewall so that network traffic can pass.

    If necessary, you can disable Inbound Service Securit y (ISS) with this login method and it will operate the same.

    Device Logout

    A LAWN Device Login behaves the same as any other authenticated LAWN device. Once the device fails to renew its DHCP lea se (by going out of range, into sleep mode, or turned off), the login session will be closed and you will need to re-aut horize the device when next you want to use it on the LAWN. We do not support a persistant login based on MAC Address because it is relatively easy to "spoof".

    Obtaining Your Device's MAC Address

    What is a MAC Address?

    A MAC address is a unique identifier attached to most network adapters (NICs). This identifier is a sequence of 12 hexad ecimal digits (0-9,A-F) most often represented like this 00:11:22:aa:bb:cc or 00-11-22-aa-bb-cc.

    How do I find my device's MAC Address?

    Nintendo DS

    1. Enter the Nintendo Wi-Fi Connection Setup in the game's menu.
    2. Select "Options," then "System Information." The MAC address is displayed on the top line.

    Sony PSP

    1. Navigate to "System Settings"
    2. Then navigate to "System Information," which is where the MAC address is listed.

    Nintendo Wii

    1. From the Wii Channel menu, select "Wii Settings" (the round button on the bottom-left of the screen with "Wii" on it ).
    2. Select "Internet," then "Console Settings."
    3. The MAC address of the Wii console is displayed on the first line.

    Sony PS3

    From the PS3 main menu screen, follow these steps:
    1. Select Settings.
    2. Select System Settings.
    3. Select System Information. This screen will display your PS3 MAC address.<

    Microsoft XBOX 360

    1. Select Wireless Information from the Advanced Settings screen in the Xbox Dashboard (under System, Network Settings).
    2. If you have the Xbox 360 Wireless Networking Adapter, this MAC address will match your console's MAC address.

    New XBOX 360 Configuration:

    The New Xbox has wireless support built in, but doesn't support WPA2 Enterprise, so it must be logged in through GTwireless Device Login.

    The MAC address to use in device login is not the wireless mac address, but the WIRED mac address.

    Aside from this difference (which caused some problems over here at ResNET), it logs in like any other device.

    @gazuolas3 - As was mentioned when we met in my office (just posting this for others to be aware of) the WiFly device you were attempting to use did not support WEP-40/65-bit, only WEP-128bit (which at the time of this writing) is not supported on GTwireless. There may be other similar products that do support 40-bit or 64-bit WEP or WPA1/2-Enterprise (WPA-PEAP) for use on GTwpa.

    I cannot seem to connect my Nintendo DS Lite to the wifi. I've set up the SSID and the WEP but it doesn't see any connection.

    March 28, 2012, 12:27 pm

    for some reason I try to log into GTWPA wireless, and they ask for authorization credentials. What do I do? I enter my user name and password and it does not work

    June 13, 2012, 1:39 pm

    I am having the same problem as gjijon3 when trying to log into GTWPA.

    With the wii u, when I try to connect to GTwpa, it asks for the security code. What am I supposed to do?

    @tdixon - If you look on this site, you will see links for instructions for GTother as well as one to obtain the Pre Shared Key. You will need this key to associate to GTother. The Wii-U will not do WPA2-Enterprise which is required for GTwpa/GTwifi. Now, each time you want to play, you will have to authenticate your Wii-U to LAWN either thru a web browser or by connecting to http://auth.lawn.gatech.edu and following the instructions to authenticate another device.

    January 13, 2013, 11:38 pm

    so I can't connect my wii to GTother, even with the given key. I keep getting the 51331 error. any ideas on what I can do or what i am doing wrong?

    @nparham3 - When reporting issues it always helps to provide the MAC address of the device as well as the device TYPE. What is this thing you are trying to put on GTother?

    April 24, 2013, 2:09 pm

    I can't log in to LAWN on my computer. It takes too long (the waiting time) and doesn't connect.

    October 15, 2013, 1:19 pm

    I can't seem to log in my roku to GTother under device log in every time I put in my MAC address it says "MAC [****************] Not Found. Please make sure that your device has obtained an IP address via DHCP." However, I have no idea how to obtain an IP address via DHCP or even what that means. Help?

    @cyarborough3 - Best thing to do is to take your device to either OIT Technology Support Center (2nd Floor Clough) or if you live in the residence halls, contact ResNet at 404-894-0044.

    After some quick testing, it appears that IEEE 802.1X authentication for wired devices doesn't work. As someone who plugs into wired ethernet ports every day, is there a reason this can't be used as an alternative to the standard login page? Is there a place I can request that we get this set up?
    John M. Douglass

    August 17, 2015, 11:30 am

    @sgilliland7 - Those ports are currently not designed for 802.1x authentication. IF you are using wired LAWN, you can self register (this is only for wired LAWN users) on register.lawn.gatech.edu when you are logged into a wired LAWN port. (see www.lawn.gatech.edu/services/registration)
