Setting it at 2Mb gives the router and modem some head room. It's ok to set it over. The modem and ISP service will still mange the speed.
For ALL Other devices, make sure you have them all collected in sequence for IP addressing, so if you have say 5 devices, not counting the PS, your first device should start at .100, then the next device at .102, all the way up to .105.
Now your beginning Local IP address will start at 192.168.0.100 the TO Local IP address will end with .105.
