The fields were still empty even after fresh reboots of several computers. I have several of them without monitors, keyboards, or mice attached. I access those computers using TightVNC, but I need to know their IP first, and having them show up in the router's list is the best way I can think of to get the IP. Not a single one ever showed up in the list. I had to either attach a monitor, or guess their IP addresses, in order to get connected to them.
I had the same result for both actual computers, and VMWare virtual machines. None of them showed up in the router. I tried a total of 4 different computers, with several reboot cycles. Still nothing.
I don't have the network up because of this problem, so I'm going from memory: I've forgotten the name of the router screen I'm thinking of here, but I think it's called "network traffic" or something like that. Anyway, the computers showed up there when they were communicating mostly UDP packets, if I remember correctly, and so I found a 3rd way to get the IP besides guessing or attaching a monitor, but they didn't always show up there right at the moment I wanted them to.
The only quirk of this system is that the network was not connected to the internet. Could there be a bug related to that? One more thing I noticed that was strange was that the IP of the first computer attached to the router was much higher than I expected. After much guessing and screwing around with monitors, I found the IP to be 192.168.1.107 instead of the 192.168.1.2 or 192.168.1.102 that I expected. I can't think of why that would be, unless the router is giving IP's nonsequentially, beginning with the 192.168.1.100 range. I couldn't find any setting to adjust that.
Also, it'd be convenient for me to be able to set a static IP for each PC, but if I do that, windows XP insists on having me set a static DNS also. Is there a way around that, where I can set each computer to my favorite easy to memorize IP addresses, but let DHCP tell them what DNS server to use? Do you have any suggestions on how to go about that?
I can also suggest that you include a brief description of each screen with helpful info like what you just wrote about the active connections list. That would be a nice little extra. You could just stuff it at the bottom for now, if you want, so it'd only take a few minutes to add, hopefully.
