wired.  No, not using network manager.  Both NIC's, eth0 and eth1, do the 
same thing.

Pardon, my initial message might have implied something incorrectly.

The only wireless device I have is an internet radio, which connects to 
the router wirelessly.

For wired devices, there's just a "skype phone" and the computer.  Now, 
the computer has *two* NIC's:  a built-in and auxilary.

I've switched the ethernet cable between one NIC and the other on the 
computer, then used ifconfig, and then even switched back to the first 
NIC, without progress.  I left that out by accident, pardon.  That both 
NIC's would have the same problem is why I suspect the router (which I 
bought used.)

When I powercycle the router, and then use ifconfig, I can see the lights 
illuminate, but they don't flicker -- just a single blink.  The router 
can be pinged fine under these circumstances, just not google/etc.  The 
oddity here is that the skype phone, connected with ethernet, and the 
wireless radio, work fine.

(From time to time, the skype phone does something similar, in that it 
will freeze or crash, but not nearly as often as the computer.)

It's more an oddity.  I can't see how or why I should be able to ping the 
router, but not the internet and *yet* the "internet" is working for 
other devices.  Finally, why would rebooting the computer fix the 
connectivity in a way bringing the interfaces down and then up doesn't?

Hope that helped to explain it, and I didn't just muddy the waters!
