The culprit: Windows (of course).
A last XP update came in overnight on April 9 and somehow my direct
internet access configuration through the router went missing.
This caused Windows to bring up a DSL / Broadband dialer dialog as a
(I noted activation of the DSL / Broadband dialer dialog at the time,
but did not think that it was significant.)
Linux box: ifconfig: IP address: 192.168.0.101
Windows box: ipconfig: IP address: 192.168.0.115
pings from one to the other work as expected
ping 18.104.22.168 works on both boxes
Before either the Linux box or the Windows box were booted and internet
sessions were established, the DLink router had an active PPPoE session
with my ISP.
And after the Linux box was booted and I started browsing, and was doing
so through the session established by the router.
(Things were as they should be.)
The Windoze box was booting at the time and, eventually, brought up the
DSL / Broadband dialer dialog. (Something it did not do the day before.)
The Windoze the DSL / Broadband dialer dialog established a session
while I was in an internet session on my Linux box.
And, somehow, the internet session on my Linux box was trashed.
By request my ISP allows for two internet sessions and after the Windoze
boot I had two sessions, a PPPoE session established by the DLink router
and one by the DSL / Broadband dialer dialog. There was no room for a
third session from the Linux box.
The behaviour of mixing two boxes and one router was very confusing
until the support people at my ISP reminded me that I was allowed two
After setting up a DSL / Broadband dialer option on the Linux box I was
able to establish an internet session through the router, but only if
the Windows box was offline.
But when there was a DSL / Broadband dialer session on the Windows box,
the Linux box was blocked.
I presume that the Windows box would be similarly blocked if the reverse
was the case. (Unconfirmed.)
All this after reconfiguring / reflashing the DLink router and checking
that the DSL modem was in the bridged mode.
And reconfiguring the internet connection configurations in both the
Windows and Linux boxes.

This after seeing the caution contained within resolv.conf I rebuilt the
