You mean the range is; 192.168.1.2 ~ 192.168.1.254 ( 192.168.1.[2..254] )
191.168.1.1 is reserved by the Router.
The Linksys BEFSR41 does not have DNS Daemon and thus 191.168.1.1 should not be
entered
into the DNS settings of the platform. That should be manually entered based
upon what the
Comcast segment provides or better yet, Enable DHCP on the platform such that it
gets the
complete stack, including the Comcast DNS servers, via DHCP.

Yep! I fumble-fingered that one.

Well, my old BEFSR41 captures the ISP (Comcast) supplied DNS addresses.
All the computers on my local network have manually assigned IP
addresses and specify 192.168.1.1 as their DNS entry. I have no problem
resolving URLs on any of them.

Well Tom I tested it on my BEFSR81 and you are correct !
That is news to me and I have installed too many BEFSR41 (Model v1, v2 and v3)
to keep track
of ;-)
Thanx for the correction.
Mea culpa !

You're welcome. I know I've made my share of mistakes and that's the
primary reason why I like public newsgroups and open source software;
there are always sharp-eyed observers to see that the emperor is fully
clothed ;-)

Thanks, all, for the kind and informative replies.
As I mentioned in some of my comments to specific replies, I tried it again,
this time only hooking up my XP box and not my wife's. (I was careful to
power everything off, then power the modem on, let it stabilize, then power
the router on, and then the PC, for each cycle.)
Things work fine when I'm connected to Port 1; they don't work when
connected to ports 2, 3, or 4.
One odd thing: on ports 2-4, while I can't download web pages, it seems I
can ping out, e.g. yahoo. The tracert to yahoo on e.g. port 4 was pretty
much the same as that on port 1 (though not quite the same; not sure if
that's because yahoo sends you to different IP addresses on a random
basis...for port 1 it went to [216.109.112.135], for port 4, to
[66.94.234.13]).
The output of ipconfig /all was the same for all four ports (except for the
specifics of the DHCP lease). Here it is for port 1:

At this point my best guess is that which one of you suggested, namely, a
bad router...
Any further thoughts?
Thanks again,
