So, here's my problem.

I have a small network of 6 computers using a sonicwall router (which has 4 LAN ports and also acts as a WLAN access point.)

The IP address of the router's LAN interface is 192.168.0.2 while it's WLAN interface's IP address is 172.16.31.1. Both interfaces have DHCP enabled with LAN serving 2 desktops (assigning IPs as 192.168.0.xx) and WLAN serving 4 laptops (assigning IPs as 172.16.31.xx).

Now, I have connected a printer to one of the desktops and I can print to it fine from both desktops (both wired). However, I cannot print from the laptops at all. I tried pinging and discovered that the 192.168.x.x machnies cannot ping the 172.16.x.x machines and vice-versa while those in the same address range can be pinged and can communicate.

How can I change my network settings so that I can print from all the machines (in both the 192.x.x.x and 172.x.x.x address ranges). Please help!

You need to change the ip address of the wireless network to
192.168.0.xxx.

I tried to do that but it doesn't work as the device gives an error saying that another interface already exists on the subnet and it does not allow that.
