Ok, your PC IP is a routable IP address. You'll noticed I changed the last octet of it to x's. That's for your protection. One does not want to publish their external IP address.
Having said that, this tells me your PC is connected directly to the internet. Or at least, that's how it looks. Typical setup with a SOHO Router is as follows:
Internet >> SOHO Router >> clients
I'm not sure how you have yours hooked up but this is how it should look with your internet plugged into the WAN port of your router and any/all clients in the LAN ports.
The first thing you need to do is ensure you have it hooked up as I said. Your ISP will provide you with an external IP address either automatically (using DHCP service) or manually (statically assigned) by giving you your TCP/IP settings.
If you have static IP from your ISP you would enter those settings in the WAN side. If automatic, ensure your WAN port is set to DHCP.
Once you have your router connected correctly to your internet connection, then your clients should all work properly if you set them to DHCP and plug them into LAN ports on your router.
