Is it configured...
Zorin should have the "lshw" package installed, otherwise install it. Then open a terminal and use the command to find out which wireless chip your Dell has. Then use the command "lsmod" to see what. if anything, is being loaded for the wireless.
Next, use that information on the Internet to tell you more about what modules should load, or if a driver or firmware has to be installed, and what to do to troubleshoot the problem.
Although many wireless devices are found and kernel modules for them loaded automatically, making them active upon booting, this is not true in all cases, and you may have to configure the device yourself.
A wired or wireless connection has three stages. The device has to be configured to work as it should, the device has to be told how to connect, and the connection has to be made. Your post doesn't make it clear which stage is causing the problem.
