How do I disable DHCP on my AP router?

I have an R7000 as my main router connect to the ONT/Modem.  I have an ethernet cord going from the LAN of R7000 to the WAN of the R7000P. The R7000P is in AP mode. The main router (R7000) has wifi disabled.  I cant seem to find where to turn DHCP off on the R7000P. Here is images of the connection. Should I just disable the DHCP on the R7000 since i dont even have wifi active on it???  Any advice would be appreciated

 

 

Model: R7000|AC1900 Smart WIFI Router, R7000P|Nighthawk AC2300 Smart WiFi Dual Band Gigabit Router

Re: How do I disable DHCP on my AP router?

If your R7000 is the main router, it must have DHCP enabled and working. If you set the R7000P in Access Point, DHCP is automatically disabled

But in these images it says it is on.

You haven't set your R7000P in proper Access Point mode, then

 

If AP is active, your main router (R7000) should assign an IP to it, which you then use to login into the R7000P AP

Re: How do I disable DHCP on my AP router?

I did a factory reset on the R7000P and reconfigured it as an AP. I set a static IP of 192.168.1.2 for the R7000P from the r7000 interface. As you can see from the images below.

   Then what's the point of using both the R7000 and the R7000P?  Are
other client devices connected to the R7000?  If not, then what's the
R7000 doing for you which the R7000P couldn't do by itself?

 

   How, exactly, did you configure the R7000P "in AP mode"?  Did you
follow the procedure in the R7000P User Manual under "Use the Router as
a WiFi Access Point", or some other scheme (namely?)?

   Plenty of context missing from those pictures.


   Using ADVANCED > Advanced Setup > Router / AP / Bridge Mode : AP Mode
should disable the DHCP server as part of the "AP Mode" configuration.


   I don't have an R7000P, so I can't test it, and so I know nothing,
but it's possible that the "DHCP On" status which you're seeing in that
"LAN Port" status report is erroneous/misleading.  It might reflect what
would be true if the R7000P were in full-function Router mode, but be
meaningless in any other mode.

   No.  The real mystery here is why the R7000 is involved in the first
place.  If you're using the R7000 as a router, with the R7000P as a WAP,
then you'd want a DHCP server someplace, and, when configured as a WAP,
the R7000P won't be doing that job.  That leaves only the R7000 to be
your DHCP server.

 

   Disabling the wireless-network radios in the R7000 does not stop it
from being a router.


   Are you seeing any actual operational problems, or is "DHCP On" your
only complaint?  If you really did have multiple (uncoordinated) DHCP
servers running on your LAN, _then_ I'd expect to see abundant problems
caused by IP-address conflicts.

 

 

> You haven't set your R7000P in proper Access Point mode, then

 

   Or, as I claim, the report is misleading.

 

> If AP is active, your main router (R7000) should assign an IP to it,

   Like, say, "192.168.1.2", as shown in that "LAN Port" status

report in the picture?  Seems (to me) to be working as expected.

 


   Lacking any report to the contrary, I believe that the R7000 is
acting as a router (with an active DHCP server), and the R7000P is
acting as a WAP (without an active DHCP server), and everything is fine,
except for that misleading "LAN Port" status report.

 

   The only remaining mystery is what value the R7000 is adding to this
equipment pile.

   Terminology: A "static" address is configured on the device itself.
What you configure on a (DHCP server on a) router is a reserved dynamic
address, not a static address.  Either one should fix the address of a
device, but some implications are different.

 

   That sounds as if you were following the User Manual, and chose the
default, "Get dynamically from existing router."  (Note, "dynamically",
not "static".  "Use fixed IP settings on this device (not recommended)"
is how you tell it to use a static LAN IP address, which you'd configure
manually under ADVANCED > Setup > LAN Setup : LAN TCP/IP Setup : ...)

 

   My conclusions remain unchanged (but I'm always open to actual
evidence, or a good counter-argument).

Re: How do I disable DHCP on my AP router?

3500 sq ft house. The utility room upstairs Is where the builder ran all the fiber to. So the ONT is in there with the r7000. Wifi signal was weak in most of the house. So I disabled the wifi on the R7000 and I ran ethernet from LAN1 of R7000 down to the laundry room which is smack in the middle of the house. Hooked it up to WAN R7000P which I then setup in AP mode. LAN2 on R7000 runs to my Xbox downstairs. LAN3 to my office and LAN4 to the master bedroom.

   Good enough for me; the R7000 has an actual purpose in life.

 

>    Are you seeing any actual operational problems, [...]

 

   If not, then my advice remains: "Don't worry; be happy."
