Cant connect to admin interface

The Wifi router is netgear AC1750 / R6700

Connected to Motorola Cable Modem

Netgear device acts only as wireless access point

Motorola acts as DHCP server.

 

I connect to wifi for browsing just fine.

When I try to connect to the wifi management interface to login and manage the device, I get the dreaded "You are not connected to your Router’s WiFi network." which is false. I am connected to it.

I have seen other posts on here that discuss the redirect for the Routerlogin.net URL . That does not solve my problem.

My default gateway (windows 7 ipconfig) is the IP of my motorola router.

The strange thing is some times I can connect and login in, it will let me browse the management interface a while and then without making any changes, it suddenly throws the not connect to the wifi error and I can no longer connect, but other computer on my network can connect and login (they are all Mac computers).

I've tried what i think is the Netgear wifi device IP (192-168-1-1) and it throws "This site cant be reached” error.

 

Not sure what to do …

 

During set up there was an option to make the wifi act as only a WAP device and I selected that. I think it turns off DHCP and puts it in bridge mode, so I'm wonder (assuming I can ever get connected again) if i change it back to its other mode, can I have 2 DHCP servers? (One on wifi device and one on cable modem)?

I can't disable it on the motorola cable modem because it has another wifi that other users use.

Thanks for any help

   Note: "cant" is a word, different from "can't".

   R6700, not R6700v2?  Firmware version?

   So, this (unspecified) "Motorola Cable Modem" would seem actually to
be a modem+router.  An actual model number would have been more helpful
than a vague description.

   "try to connect" how, exactly?  Some web browser?  Some URL?  Some
computer/device?

   Yes, it's a misleading/useless message.

   I've posted many of them, but, with my weak psychic powers, I don't
know what you read, or what you didn't understand therein.

   It should be.  And that IP address was ...?

   Can't tell how you did that, either.

   I trust that you're actually specifying "192.168.1.1", but that's
unlikely to work for an R6700 in WAP mode.

   I'm not sure what "bridge mode" means to you, but the rest of that is
generally right.  Assuming that you were looking at ADVANCED > Advanced
Setup > Wireless AP, I'd guess that you also were asked to decide how
the R6700-as-WAP was to get its (new) LAN IP address, and were given a
choice between "Get dynamically from existing router" and "Enable fixed
IP settings on this device (not recommended)".

   Having multiple DHCP servers would almost certainly be a big mistake.

   Can't, shouldn't.  Don't.  Some of the following may look familiar.

   If you got an error page which says something like, "You are not
connected to your Router's WiFi network. [...]", then welcome to what
may be the worst error message in the world.  For an explanation, try:

      https://community.netgear.com/t5/x/x/m-p/1365830

   Briefly, the idea is that "[www.]routerlogin.net" should point to
your own router, but that's true only if you use your own router for DNS
name resolution.  Irregardful, you should be able to get to the thing
using its IP address, if you can determine (or guess) that.  Normally,
that would be something like "192.168.1.1", but if you configure the
R6700 as a wireless access point, then it would need to have a LAN IP
address which is on the subnet established by your (unspecified)
"Motorola Cable Modem[+router]".

   The "[www.]routerlogin.net" names make sense only to a DNS server on
a Netgear router, and you're not using a Netgear router as a DNS server
(because an R6700-as-WAP doesn't run a DNS server, either), so you can
forget all about using those names to reach the R6700-as-WAP.  You'll
need to use its IP address, instead.

   If you had chosen ""Enable fixed IP settings on this device (not
recommended)", then you should know which address you gave it, and you
might now be able to reach it at that address.

   Presumably, you chose "Get dynamically from existing router".  That
was fine, and it prevented you from manually selecting bad parameter
values, but it does mean that only the (unspecified) "Motorola Cable
Modem[+router]" knows which address it gave to the R6700-as-WAP.  And
that could change from time to time.

   Knowing nothing about your (unspecified) "Motorola
CableModem[+router]" makes it hard to give specific advice, but I'd
guess that somewhere in the user interface on that device, there's some
kind of report on what Netgear calls "Attached Devices".  It might be
under a name like "DHCP clients".  That's where you should be able to
find the IP address which was issued to your R6700-as-WAP, and that
address in a web browser should get you to the web server on the
R6700-as-WAP.

   Once you find it, you might look around in the Motorola router's
interface for a way to assign the R6700 a fixed ("reserved") address
(again, something to do with its DHCP server).  With that done, you
would always know which IP address to use to talk to the R6700-as-WAP.
