Netgear R6250 switching to AP mode does not turn off DHCP
Firmware version : V1.0.4.38_10.1.30
OS: Windows 10 Pro 64 bit
Firmware Version
V1.0.4.38_10.1.30
I have switched the R6250 to AP mode as shown in the attached file. According to the manual, when it is switched into this mode,
the DHCP is disabled and it will hand out ip addresses from the existing router. My existing router is handing out the ip addresses
192.168.0.*. The DHCP on the R6250 is still on (screenshot in the attached file) and is handing out the addresses 192.168.10.*.
Due to this, the computers attached to it cannot see the computers attached to my existing router.
How do I turn off the DHCP while in AP mode? As an alternative, do I set a static IP and use the gateway ip address and dns addresses from my current router? Please advise and thanks in advance.
You were correct! I had the line going from my existing router to a voip box that was handing out the 192.168.10.* ip addresses. Thanks a lot for getting me to look at the wiring!

"it" won't; "the existing router" will. The R6250-as-WAP would just
pass the DHCP data along.> [...] The DHCP on the R6250 is still on (screenshot in the attached
> file) [...]That picture shows me nothing like that. I'd believe "Operation Mode
AP". Are you looking at both ends of the cable connecting the
R6250-as-WAP and your (unspecified) "the existing router"?My interpretation of that picture would be that the R6250-as-WAP is
connected to some router (DHCP server) which is using the "192.168.10.*"
subnet. That may not be the router which you think it is.
Notice that the R6250 LAN IP address is "192.168.10.100". I'd
interpret "DHCP ON" there as meaning that the R6250 is using DHCP to get
its _own_ (LAN) IP address (as in "Get dynamically from existing
router."), not that its own DHCP server is (still) operating.If you pull the Ethernet cable from the R6250 WAN/Internet port, and
stick it into some DHCP-using computer, instead, then what does that
computer get as _its_ IP address? (My money would be on "192.168.10.x",
which it would be getting from something other than the disconnected
R6250-as-WAP.)> How do I turn off the DHCP while in AP mode? As an alternative, [...]
Pending further investigation, I'd claim that it _is_ off, and that
the R6250 knows more about its environment than you do. But it should
be easy to prove me wrong (if I am). Until then, I wouldn't try to
outsmart the R6250 by setting any static IP parameters anyplace.Thanks for responding! Look closer at the second picture. It show DHCP on. That is why it is generating a different set of ips.
Please advise.
I only have my existing router, a Actiontec C3000A from Century Link and this router in my system. I will try your advice today and see what ip address I get when I plug it into another laptop. Will keep you posted. Thanks!

I did. Hence:
> [...] I'd interpret "DHCP ON" [...]
> [...] That is why it is generating a different set of ips.I'm waiting for evidence that the R6250 is the culprit and not the
victim.Another interesting experiment would be to disconnect the R6250 from
everything except (it power adapter and) one DHCP-using computer, and
see if that computer gets a valid (not self-assigned) IP address. If
the R6250-as-WAP really _is_ acting as a DHCP server, then the computer
should _not_ get a self-assigned IP address.> I only have my existing router, [...]
I'm sure that you believe that, but that's not the same as proof.
Hence the question (still unanswered):> [...] Are you looking at both ends of the cable connecting the
> R6250-as-WAP and your (unspecified) "the existing router"?As always with Netgear routers, the firmware could be defective, so
that it does not disable the DHCP server when in WAP mode, but who
decided on "192.168.10.x"? It's easier for me to believe that you have
some other gizmo causing trouble than that the R6250-as-WAP plucked that
subnet out of thin air, and is using it for its own (should-be-disabled)
DHCP server.These forums see many oddball DHCP complaints, but I can't recall any
where a router-as-WAP was running a DHCP server. But I'm always open to
actual evidence.
