Why? And connected it to what?

You seem to be very easily annoyed. Is the CM1100 a replacement for
some other modem? (What was it?)

Ok. For future reference, what are you using as a router?

It does? Did you actually try it, or are you basing your complaint
on how you expect this stuff to work?

> [...] I am not going to reconfigure my network to 1.92.168.100.xxx !

I would advise against doing that. Did anyone advise you to do that,
or was it your own idea?

> Is there a workaround for this stupidity? [...]

Which/whose?

Visit http://netgear.com/support , put in your model number, and look
for Documentation. Get the User Manual (at least). Read.

Don't go looking for trouble where there is none?

> [...] This cannot be a new problem [...]

Especially if it's not actually a problem.

If you are replacing an old modem+router of some kind with a CM1100,
which is only a modem, then you can expect to have problems until you
get a router to go with it.

General advice: You might have more success if you described the
actual problem which you are trying to solve, rather than asking how to
implement some particular "solution" (or refusal to do something), which
may have little or nothing to do with the actual problem (whatever it
might be).

   Yes, it is. Make a new bookmark for "192.168.100.1". When you use
that (special) address in your web browser, your (unspecified) "a
Linksys WAP/router" will see that address, notice that it's not on its
own LAN, and send it off toward your ISP. That is, to the CM1100, which
will intercept it, and respond appropriately. There's no need to do
anything different/special on your ("192.168.2.*") LAN to make that
work.

   Did you see anything in any of them which suggested (let alone
demanded) that you "reconfigure [your] network to 1.92.168.100.xxx !"?

> [...] I do enough to get by and then I stop.

   That's fine, if you know where "enough" ends.

>    Don't go looking for trouble where there is none?

   Still my advice.

  Thanks. That's exactly what I was looking for. It would have been nice to get it without the snotty attitude, but I'll take it either way. Since that is an unroutable IP I'm surprised the tip works. I would have expected the Linksys to refuse to forward it, but apparently not -- assuming you have actually made/seen this work.

       Exactly. Hence:

       In the words of the philosopher Williams, "If you don't think too
    good, don't think too much."
    
    > [...] the Linksys to refuse to forward it, but apparently not -
    
       I'd expect that your ISP would "refuse to forward it", if that's any
    consolation.
    
    > [...] assuming you have actually made/seen this work.
    
       Everyone who owns a cable modem has (or could have) seen this work.
    
    > [...] It would have been nice to get it without the snotty attitude,

       Fix your own attitude, and that of others may follow, with no extra
    effort on anyone's part. Screaming about all "this stupidity" which
    you're being forced to endure, rather than _asking_ about how the simple
    procedures in the various User Manuals could possibly work, for example,
    might have been a better start. Just a thought.
    
       Deciding whether the original problem involved "stupidity" someplace,
    or just a smattering of ignorance (which is normally a simpler obstacle
    to overcome), is left as an exercise for the reader.
