Hello! According to your computer’s routing table, the problem isn’t the router.

You will have to set a static IP address on your computer for the 192.168.8.* range. The reason you can’t connect is because your computer is in the 192.168.12.0 range, so it can’t talk to the 192.168.8.1 range.

Once you do set a static IP make sure your laptops address is NOT 192.168.8.1, since that IP is already used by the router. Instead set your laptop to something like 192.168.8.10.
