1. Connect to ResNet Wireless Network

1.  Please see Connect to ResNet Wireless Network

2. Check for Account Issues

1. Try to log into another tool that requires your Active Directory credentials to confirm that your username & password works (Canvas, Ecotime, etc.). Your username is the first part of your UCSD email (everything before @ucsd.edu). 
2. If you are a new student and do not know your username, please go to sdacs.ucsd.edu/~icc/index.php and use the option under "Forgot Username or New Student?"
3. If your password is incorrect, please reset it by going to password.ucsd.edu

3. Check for Blocks

1. Check your UCSD email to see if your device is blocked due to a DMCA violation or compromised machine. If so, please follow the steps outlined in the respective email. 
2. Go to amiblocked.ucsd.edu to check if you are border blocked. A typical indication that you are border blocked is that the only websites you're unable to access are UCSD websites. If your device is border blocked, please submit a ticket or call the ITS Service Desk at (858) 246-4357 to request to be unblocked by the Security team.

Windows

If the previous steps didn’t work, try to uninstall the network adapter driver, and then restart your computer. Windows will automatically install the latest driver. Consider this approach if your network connection stopped working properly after a recent update.

Before uninstalling, make sure you have drivers available as a backup. Visit the PC manufacturer’s website and download the latest network adapter driver from there. If your PC can't connect to the internet, you'll need to download a driver on a different PC and save it to a USB flash drive so you can install the driver on your PC. You’ll need to know the PC manufacturer and model name or number.

1. In the search box on the taskbar, type Device Manager, and then select Device Manager from the list of results.
2. Expand Network adapters, and locate the network adapter for your device.
3. Select the network adapter, and then select Uninstall device > the Delete the driver software for this device check box > Uninstall.
4. After uninstalling the driver, select the Start button > Power > Restart.
5. After your PC restarts, Windows will automatically look for and install the network adapter driver. Check to see if that fixes your connection problem. If Windows doesn't automatically install a driver, try to install the backup driver you saved before uninstalling.

Mac

If the previous steps didn't work, try to update the macOS software if your device is capable.

1. Click on Apple menu > System Preferences, then click Software Update.
