If UWNet is not working for you, try configuring and using eduroam on your computer. eduroam is the preferred wireless network on the UW-Madison campus.

See Connect to Campus Wi-Fi for instructions to connect to eduroam. 

1. If you are connecting using an Ethernet cable, try unplugging the cable plugging it back in after 15 seconds.

2. If you are connected wirelessly, try disconnecting from your current Wi-Fi network and rejoining it.

3. Have you registered your devices? UWNet requires each device to be registered in order to access the network. 

4. Make sure your network adapters are enabled. This document shows you how to check for that below. 

5. Try rebooting your computer.

6. Make sure your computer is updated to the newest version.

7. Do you have viruses prohibiting your use of the internet? Try running a virus scan with an application like Malwarebytes or AVAST Antivirus.

8. If you connect to a router either wired or wirelessly, make sure that it is connected to the wall jack.

9. Routers need to be registered with UWNet in order to use them. 

10. If you are using an Ethernet cable, make sure that that cable is not faulty by testing your connection with another wall jack. Or by testing the same jack with a different cable. 

11. Turn off iCloud Backups in the background. If you only have 5GB iCloud storage (the default free storage) there is no reason to have this on at all. If you pay for iCloud, do backups manually occasionally instead of having your MacBook backup automatically in the background.
