LapLAN is a service that allows you to connect your laptop to the University network using an Ethernet cable. LapLAN is provided in several public and departmental areas.
If your laptop has a wireless card installed, you may wish to connect to the wireless network instead of LapLAN2. Wireless is somewhat slower than LapLAN2 (though quite sufficient for most normal purposes), but LapLAN2 has a limited number of access points.
LapLAN2 is a new version of LapLAN. If you have previously signed up for LapLAN, you must re-register for LapLAN2. However, if you have registered to use the Wireless/VPN service, you are already registered for LapLAN2.
LapLAN2 ports are marked with stickers. The stickers may be red or yellow.
There are also LapLAN2 ports in some bookable rooms and departmental areas.
These instructions enable you to register for LapLAN2 through EASE. If you are not already registered with EASE, you must first do that. See the link below for guidance.
If you are already registered for Wireless/VPN or LapLAN2, you can skip this section.
You are now registered for LapLAN2, Wireless and VPN using your University user name and the password that you have just provided.
You won't be sent a confirmation email after registering.
Most computers running Windows XP or Vista will already have an Ethernet card installed. If you are not sure whether you have one, or it doesn't seem to be working properly, you should check if it's installed correctly:
If you don't have a Network Adapters entry this means that there is no network card on your laptop, and you need to buy an external PCMCIA card.
Most computers running Windows XP or Vista will have the necessary network protocols are installed. However you can check this in case of problems:
If Internet Protocol (TCP/IP) is not in the list, you will need to install it.To do this, click on the Install... button, double-click on Protocol, and double-click on Internet Protocol (TCP/IP). The installation may take some time. When it finishes, you will be returned to the properties window.
It is recommended that you install the Microsoft TCP/IP version 6 protocol.
If your laptop does not have an Ethernet card installed, or if it is installed incorrectly, please contact the IS Helpline (IS.Helpline@ed.ac.uk or 0131 651 51 51) for advice about solving the problem.
The security of your laptop is your responsibility. You must have reasonable security measures in place before connecting your computer to a network.
You must install a virus scanner and keep it up to date. Copies of Kaspersky Anti-Virus can be downloaded from the University free of charge. More information is available in the document below:
A firewall prevents other computers on the network from connecting to yours without permission. As of Service Pack 2, Windows XP has a built-in firewall. Unless you have other firewall software installed, you should turn it on:
Windows Vista has a built-in firewall which is turned on by default.
Windows Update can automatically download and install updates to Windows XP. To turn it on:
Windows Vista has the update option turned on by default.
You should never leave your computer unattended in a public place.
To prevent data loss, you should make regular backups of your important files. See the link below for more information:
There are two ways in which you can set up your laptop for LapLAN2. With basic configuration, you can use any LapLAN2 port, and the setup is simpler, but you will be accessing the network through a shared gateway, and will have to log in every time you connect. Advanced Configuration (802.1X) allows you to access the network directly, but is only available at LapLAN2 outlets marked with a red sticker.
Unplug your laptop from any ethernet connection before configuring it.
The status under Local Area Connection will change to 'Acquiring Network Address'. It should then change to 'Connected'. Check your IP address:
Your IP address should begin with 129.215.47. If it doesn't, then you need to repair your IP address, as described in the Troubleshooting section.
Finally, authenticate your connection:
You are now connected to LapLAN2. You do not need to use VPN to make the connection secure.
Configure your laptop as described in the Basic Configuration section, but complete the following before you plug in the ethernet cable:
If authentication is successful, your computer will remember your credentials, and next time you want to connect to LapLAN2, you can simply plug in the cable without needing to log in.
Your IP address should begin with 129.215.76. If it doesn't, refer to the Troubleshooting section:
If you are not assigned the correct IP address, then you need to repair it.
If you still do not have a valid IP address, then contact the Helpline.
If your IP address is correct but you are not redirected to the LapLAN2 authentication page, then check which page your browser is attempting to load. You may have to disable the cache or change your home page to something that begins with http:// rather than https://.
Very occasionally there may be load problems with the authentication gateway, which results in a delay in loading the login page. A workaround to avoid this delay is to use VPN as you would for the wireless network, although using a VPN on LapLAN2 is not a requirement for using the full range of IP applications.
If you are assigned an IP address beginning with 129.215.47, this may be because you are using a LapLAN2 outlet marked with a yellow sticker, or because there has been an authentication failure. To repeat the 802.1X authentication, remove the ethernet cable from your computer, wait a few seconds, and replug it. If your IP address is still 129.215.47.?, you can use basic configuration and log in using your web browser.
If the problem persists, then check the 802.1X configuration of your ethernet interface.
If 802.1X authentication continues to fail on the port and is successful on a different port, you should report the failing port to your user support team.
The connection to the university network is secure, and you do not have to use VPN or a proxy server. Once you are connected to LapLAN2, you can use the full range of IP applications. Note: this policy may be reviewed if it is seen to be abused. Users are reminded about their obligations under the Computing Regulations, which can be read here:
You can print to certain open access lab printers, as long as you have credit on your printing account. For more information, please see the document below:
You can access your Networked drive (M: drive), where you usually save files when using the open access computers, from LapLAN2. For more information, please see the document here:
