A few weeks ago, Nephew's computer -- wired via the router -- stopped spewing forth the internet. My laptop -- wirelessly doing the deed via the same router -- was fine

My immediate reaction is to say that your wireless networking card and wired networking card are two separate bits of kit so it's quite possible one is working when the other is not

so it's quite possible one is working when the other is not.
On my laptop, yeah, I can see that. I've not connected via wire with the laptop since March. But the reason I tried to hook my laptop up to the wired was because Nephew's PC -- connected via wire -- stopped working while mine -- connected via wireless to the same router -- worked fine. So if I'm following your suggestion, both our wired cards are having issues at the same time?
but is possibly more likely to be a loose connection in the router if you're connecting to the same router connector This one makes a great deal of sense to me, as I'm pretty sure I just always go for the router connection marked '1'. I guess it appeals to my sense of order or something, because there are four slots back there and I know it doesn't matter which one I use. I'll experiment with that next time

Now, I know you've tried to be explicit in desscribing your troubleshooting, but I notice that some necessary information appears to be missing ...

I guess I did a few lot of key bits of info out, huh?
The cables running from the cable box to the router and from the router to Nephew's PC are identical, or look that way to me. I'm going to call the one running from the cable box to router, 'A,' and the one running from router to his PC, 'B'.
First, I tried running 'B' from the router to my laptop instead of his PC. My laptop wouldn't connect that way.
Second, I tried skipping the router completely and running 'A' from the cable box to my laptop. My laptop still wouldn't connect.
I then swapped cables around and tried both options (running from the router and then directly from the cable box) with both cables. I never got a connection.
When trying from the router, I always used the slot on the router marked '1.' (There are four, and Lex suggested trying a different one of those. This makes sense to me. I'll try it first the next time this happens.)
did you check your operating system networking settings to be sure the laptop knew which adapter it should be using? Um, no.

For the desktop, you may have a problem with the internal adapter being flaky. Or, a software firewall problem (if you use a software firewall). Or, it could be a flaky connection / flaky receptacle at the back of the router.
For the cables, you might have a cable with touchy wiring at the plug(s).
Only the latter would have anything to do with your laptop not connecting directly via the cable modem itself. If you have eliminated the router from the chain and if you can determine that the cable you use to hook the laptop directly up to the modem is 100% functional, and it doesn't work, then it seems to me you are left with something to do with the laptop itself as a culprit for that. Software firewall, hardware adapter, netwiork plug receptacle, network settings (for example, if you try it again and don't connect then maybe just quickly check your settings to be sure the internal network adapter is actually enabled).
Hope it never happens again, but if it does there are ways to try ruling stuff out ;-).
