You are in the wrong forum. Be that as it may,
You should let your computer be assigned an address by DHCP given by the router.
If you need to assign an address, you should use some thing like:
192.168.0.20, 192.168.0.22, and 192.168.0.25. subnet mask: 255.255.255.0
You should be able to search the network forum for answers as this has come up many times.
It is bad luck to be superstitious.
