The router password is usually to gain administrative access to the router.
But are both of your machines on the same side of the router? To see your arp table, get to an OS command prompt, and type: arp -a This will show you the internet address and corresponding network address of each known machine on the network. The command to see your routing table varies with your operating system Windows: route print OSX: netstat -r Linux: route This will show you information about which machine to talk to for machines which are outside of your network, and there is either a bitmask showing you which part of the listed ip address selects the network (the 1s in the bitmask) and which part identifies a machine on the network (the 0s in the bitmask) or there will be a slash and a small integer which says how many bits of the ip address are used to select that particular network (counting from the left - although they use bitmasks, the convention is that those masks are all 1s followed by all 0s). You already know, of course, that ip addresses are expressed using a dotted decimal notation. For example, 1.2.3.4 corresponds to these bits: (32#2)#:256#.1 2 3 4 And you probably knew (but have not been thinking about) the idea that "IP" in "ip address" stands for "internet protocol" - and that that is a protocol for sending messages between different networks (such as an ethernet network or a wifi network, for example). Anyways, there's more that might be relevant, but hopefully this is enough that you can ask the next question.
