Upgrades to LTSG's wireless network where made during the summer of 2011. If you have accessed the network before this change, but have not been able to access it since you will need to recreate your network connection.
If you have a laptop computer or other wireless device you will need to delete the old LTSG wireless network and connect to the new one.
You can delete the old network, from a Windows 7 ( or Vista) Computer, by clicking the start button and in the Search box type "Manage Wireless Networks" and hit enter. A screen will open with a list of Wireless networks you have connected too. Click on the LTSG network and press the delete key. Confirm you want to delete the network. Close that window.
Then connect to the network as you normally would for the first time using the password which is posted on campus.
