No harm in trying :-}
Just make a note of any existing setting for the DNS server and go back to that if ness.
OTOH, since it works using the IP address for testing you could stick with that....

The PCs as well as iPad use the same router. In fact if I enter in the Safari on iPad address 192.168.0.1 I get the login screen to the router. But when I enter in iPad address I get message that the server cannot be found.

>>>I'm not familiar with the iPad or how to configure networking for it. My guess is somehow you need to tell it to use your router's IP address as a DNS server so it will get information on server and PC names on your network.
