Do you mean wireless from computer to router or wireless from router/modem to your ISP frontier? If wireless to frontier then that makes it complicated. The firewall may be at their end.

If it's just a home wireless set up, then it will be your router/modem that has the firewall. You will need to log into them & enable UPnP. Else if they don't support UPnP then you will need to port forward. I don't know which devices you are using as requested, so I can't help you further. It's not so hard to find the device & find a brand name & model number on it.
