I think I found one place where the router isn't acting as documented.
If I read page 74 of the WRT54G owners manual correctly
( http://media-server.amazon.com/media/mole/MANUAL000000300.pdf ),
the "Connection" should be reported as "Disconnected" in the morning aft
the modem has been powered down for a long period of time (hours).

But, I remember testing this out intuitively and the router clearly said it
was "connected" when it was certainly not connected. Even the OLD IP
ADDRESS showed up on this router page when I checked yesterday and this
morning. In a way, it seems that the router is confused as it "thinks" it's
connected and it "thinks" it has an IP address ... but it is neither
connected nor does it have an IP address.

Of course, rebooting the router clears all this confusion up ... but, I had
tried hitting the "disconnect" and then "reconnect" button on the router
web page but it didn't work this morning when I tested it.

Here, specifically, is what "troubleshooting" page 74 of the Linksys WRT54G
owners manual says about this:

14. My DSL service˙s PPPoE is always disconnecting.
PPPoE is not actually a dedicated or always-on connection. The DSL ISP can
disconnect the service after a period of inactivity, just like a normal
phone dialup connection to the Internet. There is a setup option to ´keep
aliveˇ the connection. This may not always work, so you may need to
re-establish connection periodically.
A. To connect to the Router, go to the web browser,
and enter http://192.168.1.1 or the IP address of the Router.
B. Enter the password, if asked.
C. On the Setup screen, select the option Keep Alive, and set the Redial
Period option at 20 (seconds).
D. Click the Apply button.
E. Click the Status tab, and click the Connect button.
F. You may see the login status display as Connecting. Press the F5 key to
refresh the screen, until you see the login status display as Connected.
G. Click the Apply button to continue.
If the connection is lost again, follow steps E to G to re-establish
connection.

If I interpret this troubleshooting help correctly, after I've powered down
my modem overnight, in the morning the router should not be listing the old
IP address as "connected". The router should be listing no ip address and
it should indicate it's "disconnected".

Yes?

Yes. But did you not select the always on option during some of your
attempts to have your IP change. That may be telling the router to think it
is connected when it is not.

I think this is the fundamental router problem (most likely a bug).
I think the router "thinks" it is connected when, in fact, it hasn't been
connected for (at least 4) hours because the modem has been powered off.
Because the router "thinks" it's connected, it sees no need to connect
again to obtain a different IP address, even if I wait for an hour or more
after powering up the modem. This would seem, to me, to be a router bug.

The option I was using earlier in the time span of this thread was:
Keep Alive: Redial Period = 30 sec

But, for the past few days, I followed the suggestion to set:
Connect on Demand: Max Idle Time = 5 min

I'm assuming that a "demand" is an Opera browser request to
"www.google.com" or the "ipconfig /relase" + "ipconfig /renew" sequence or
a "ping www.google.com", etc.

QUESTION FOR FIREWALL USERS:
If you power down your modem long enough for your ISP to relinquish your
DHCP IP address, when you power up your modem in the morning, does your
router fail to connect back to the ISP?

I suspect this inability to connect is a bona-fide bug in the Linksys
WRT54G router. It would be interesting to see if other routers have the
same bug.

You flat-out don't know what you are talking about here.

No

It's most likely that the IP is assigned to the modem's MAC and is
provisioned to your account with the ISP. You can try, try and try some
more to change the IP, that you cannot do. I don't know about the ISP you
are using, but if that IP from the ISP is provisioned to the modem's MAC and
is linked to your account with the ISP, that IP is NOT changing, unless you
call them to have the ISP change it or you don't pay the bill and leave it
cut off for awhile and then and only then based on the two conditions will
that IP be changed.

Again, you flat-out don't know what you're talking about.

You can lead a horse to water, but I guess in some cases, the horse has to
be clubbed and kicked *head* to make the horse drink. <g>

Hi Duane,
I never said I did. That's why I ask you experts for help so that once the
ISP gives up on an IP address, that the router would then dial in asking
for a new one (without resorting to rebooting the router).

Hi Duane,
I'm wondering if you understand what I said? I get a new IP address any
time I want. All I have to do is wait about 4 hours with the modem turned
off and reboot the router after I turn on the modem. So, why do you say I
can't CHANGE the IP address? Am I misunderstanding you or are you
misundertanding me? Please clarify.

Hi Duane,
Again, I fail to understand you or you fail to understand me.
With DHCP you get a different IP address every time I leave the modem off
overnight and reboot both the modem and router in the morning. So, why do
you insist on saying I have to not pay my bill in order to get a new IP
address. Again, am I misunderstanding you or are you misunderstanding me.
Please clarify.

Hi Duane,
If I understand you correctly (and you'll need to clarify if I don't), you
say I can't change my IP address (assuming I pay my bill). But, I can
easily change my IP address. I do it almost every day (see explanations in
this thread ... there are probably fifty of them saying so). Everyone else
understood me ... but you ... or ... am I misunderstanding you? Please
clarify.
