Ifit module

Options
I am wanting to know if anyone has an ifit treadmill or bike that has the ifit built into it and does not have the wifi module. I have a treadmill that uses the module and it used to work fine but know I can no longer get it to find the DNS to hook up with my internet. I have had my internet checked and it works and have even tried a wireless hotspot. I am just wondering if the built in Ifit is working because I am thinking about upgrading, but I do not want to spend the money if it will not work either.
