Router problem

Hello,
I just replaced a cisco 1700 router with a Sonicwall TZ170 router. The problem that I am having is the Sonicwall router will not recognize the Wlan cable when it is attached. I don’t know why. When the Cisco router is attached it the cable works fine, but when I unplug it and attach the Sonicwall the cable seems to not work. I don’t know what is wrong, this is on a Frame Relay internet connection. Please any help would be great, Thank you
