On a router when connected, the router gives your devices an IP address via its DHCP. That creates the LAN. You ISP via the modem provides the Internet signal to the router and it had the WAN IP Address. You do NOT need the Internet signal to the router to access the router. Just use a Browser as mentioned above.
What I don't understand is "ip not responding w/o intrernet connection and login.net requiers internet for dns, right??"? Where did you get that idea from?
"what is the next step? if i use the yellow cable and plug it pc to lan port 1, is that the secret back door?"
Why do you think this is valid? There is no 'secret backdoor'? Use a BROWSER to log into the router.
"i did verified 192.168.1.254 responded to ping when entire lan to wan is up, ..."
Totally confused with that statement? I'm beging to think you are not connected to the router but you modem is also a router? What is your modem make and model? What is the IP Address of your PC?
Once you don't have access to Internet, check your device's IP address. Ping your router and if it's replying, then you should be able to access your router.
In case there is a ISP CPE in front of the router (e.g. a cable modem, a router, ...) which does fall-back to issue RFC1918 private IP addresses - and if this is overlapping with the router LAN subnet - the routers are (unfortunately) overly "smart" and reconfigure the local subnet to some 10.x.x.x /254

What, exactly, does "lose access" mean to you? As usual, showing actual actions with their actual results (error messages, LED indicators, ...) can be more helpful than vague descriptions or interpretations.

Is that accurate? Firmware version? Connected to what?

What's at "192.168.1.254"? The default LAN IP address of an R8000P is "192.168.1.1".

When you do what? "unable" is not a useful problem description. It does not say what you did. It does not say what happened when you did it. See "As usual, [...]", above.

Explain what you're doing, and what happens when you do it?

Huh? Which "the yellow cable"? Where is it connected now? Why
would you need a "secret back door" to anything?
> there has to be a way to access this router w/o internet access.
Visit http://netgear.com/support , put in your model number, and look for Documentation. Get the User Manual. Read. If it were impossible to communicate with a router until you have an Internet connection, then how could anyone configure a new router?
> ip not responding w/o intrernet connection [...]
I don't know what that means to you. "IP" = Internet Protocol. See "As usual, [...]", above.
> [...] and login.net requiers internet for dns, right??
No, using "routerlogin.net" does not require Internet access. A Netgear router should handle such a reference locally.
