R6400; Router works, but not able to reach router for conifiguration

[Heimi]

I got a new Netgear R6400 router. I use it as a WiFi access point -  My  main router is a AVM Fritz.Box. Notebook Win8.1

Afer unboxing i could configurate the device via LAN Cable und routerlogin.net.

I changed the WLAN Password und

then I disabled the DHCP Server (because the Fritz.Box is managening my network).

But after this the following happend:

1) The Wlan and the LAN still working - all connected devices get access to the Internet.

2) But I can´t reach the Config-site of the R6400 any more (Wlan and Lan). I tried it several ways: with the nighthawk app, with LAN Cable and http://192.168.1.1, routerlogin.net, with my Notebook, with smartphone

--> nothing works.

3) At the Fritzbox router I can check all Devices conneted to LAN oder WLAN

 -->  The R6400 router is not on the liste??

I did a Reset to factory default values ---> same story begins

   Is that accurate?  Not R6400v2?  Look at the product label.  Firmware
version?

> [...] I use it as a WiFi access point [...]

   Visit http://netgear.com/support , put in your (actual) model number,
and look for Documentation.  Get the User Manual.  Read.  Look for a
topic like "Use the Router as a Wireless Access Point".

> [...] I disabled the DHCP Server [...]

   Is that all you did, or did you follow the instructions in the User
Manual to change it to "Wireless AP" mode?  I'd suggest following the
procedure in the User Manual, which also shows how to connect the
R6400[vX]-as-WAP to the main router.  (And if you don't do the official
mode change, then you could not use the WAN/Internet port on the
R6400[vX]-as-WAP.)

> 2) But I can't reach the Config-site of the R6400 any more (Wlan and

   When you select "Wireless AP" mode, the R6400[vX]-as-WAP must get a
new LAN IP address (different from "192.168.1.1).  Exactly what that new
address will be depends on whether you choose "Get dynamically from
existing router" or "Enable fixed IP settings on this device (not
recommended)".  If you don't do the official mode change, then it may
not get a new/different LAN IP address, which could cause problems.

   If your client device is connected to the R6400[vX]-as-WAP, then a
name like "routerlogin.net" might still work, but the new LAN IP address
should work from anywhere on your LAN.

   Try following the "Wireless AP" mode-change procedure in the User
Manual, and see if that improves things.  Viel Glueck.

Thanks a lot for the answers.

Yes it is a R6400v2

I got the manuel, and I used the described process to switch off the DHCP Server.

Try the bit in the manual "Use the Router as a Wireless Access Point".

But be aware of this:

Disabled Features on the Router when set to AP Mode | Answer | NETGEAR Support

And, remember, whenever you reset the R6400v2 it will revert to router mode.

It´s done!!!!

You were totaly right.   My mistake. 

I did a reset. And than I chose "AP-Mode" --> it works!

Thanks a lot!!!

Glad it worked. It is easy to get muddled with these things, especially when they get into strange terminology.

For real confusion try "bridge mode".

   That's only part of the job.

> [...] I chose "AP-Mode" [...]

   Selecting "AP-Mode" does disable the DHCP server, but it does other
things as well, including:

      1. Tell the R6400v2-as-WAP to get its LAN IP address using DHCP
         ("Get dynamically from existing router").

      2. Configure the WAN/Internet port as another (special?) LAN port.

      3. More?

   What could go wrong?  (Thanks for the report.)
