Security - Removing a Blackhole Block
If your computer is unable to connect to the campus network Wireless UWNet, it is possible that your internet access has been disabled. Internet connectivity has been denied to computers that have been infected by virus or other security vulnerabilities that can compromise the University network.
You can call the DoIT Help Desk (264-4357) to determine if your access has been disabled. If it has been disabled, the following
steps will need to be completed before Internet access can be restored.
If it is found that your computer has been disabled, please complete the following steps to restore your internet access.
If you are not able to perform these steps yourself, the DoIT Help Desk offers a free virus detection and removal service
for up to 2 hours.
