WordPress URL not working?

I am using WordPress, I have some URL issue.

My current URL is IP address on server: http://www.192.10.1.22/states/?q=ohio

I want URL: http://www.192.10.1.22/states/ohio

I used following code in functions.php file and it’s working in my
local but when I upload in Cpanel then it’s now working given me an error
page not found.

function custom_rewrite_rule() {
      add_rewrite_rule(        
            'states/([^/]*)/?',        
            'index.php/states/?q=$1',        
            'top' );
    }

    add_action('init', 'custom_rewrite_rule', 10, 0);

I also update permalink and apache mode_rewrite is also on. So how could I solve this issue?
