Duplicate IP Address
I just got this router yesterday and setup was easy. However, when I look at the Advanced tab I see duplicate IP addresses: The first is my Samsumg phone (checked the MAC address) and the second is ...
Okay...I didn't change the DHCP pool range but I did give my printer a static IP 0f .100. I have seven devices total and they all get assigned an IP below .010 so I should be good. Thanks for your help.

"limit"? Everything's a limit. Which value did you change?
"changed my printer"? You're still configuring your printer with a
static address (configured on the printer), not reserving a dynamic
address for the printer on the router, and configuring your printer to
use DHCP?
As usual, many things are possible. Some of them even work reliably.
Under LAN Setup the "Use Router as DHCP server" is checked. The starting IP address is 192.168.1.2 . I changed the ending IP address to 192.168.1.100 so my printer at .110 is outside the range.
> Under LAN Setup [...]
Sounds reasonable. So long as you have some non-pool addresses,
like, say, ".101" - ".254", you should be able to use those as reserved
dynamic or static addresses. What could go wrong?> [...] ending IP address to 192.168.1.100 [...]
Some people might have chosen ".99" there, so that _any_ ".1xx" (or
".2xx") value would be easy to recognize as non-pool.I wouldn't say this issue is "solved" by no mean. I've had this router for over a year, and I'm pretty familiar with its advanced configuration settings. That said, I too started getting duplicate assigned IP addresses on my network immediately after updating. I have just over 80 devices on my network (smart home), and at least 3 or 4 keep getting duplicated with no rhyme or reason - sometimes it'll be a duplicate between my 5GHz & 2.4GHz devices, sometimes between the router and my AP unit, and then sometimes duped solely on the router's 2.4Ghz band. I've tried soft/hard rebooting, disconnecting power for 30+ minutes, manually reloading firmware, clearing and reloading configurations, changing router/AP boot order, etc; all with no help. Downgraded it back to v1.4.1.42, and everything again works as well as it used it.
I probably won't check back in on this, as I'm not staying on this setup much longer... it just can't handle the demands I'm asking of it anymore, so I'm moving on up to a Unifi HD setup. I just wanted to comment here to report that v1.4.1.50 randomly breaks IP assignment protocols. I'd suggest just downgrading to v1.4.1.42 until Netgears figures things out (if they even attempt it), though that version had it's own issues (on occassion drops WiFi settings to factory default, as well as refusing to update the connected devices list 90% of the time).

Different hardware, different firmware, different environment? All
good reasons to start a new thread, instead of diverting this one.
Unless I missed something, this thread dealt with a printer having a
static address which was still in the DHCP pool. I see no particular
reason to believe that your problem is similar, unless you also assign
static IP addresses from your DHCP pool. There's more than one way to
get address conflicts with DHCP, most notably, having two active,
uncoordinated DHCP servers.Yeah saw later on that this was for a different router, but couldn't delete or modify my post for some odd reason. Wasn't trying to divert anything... just searched for "R7900P duplicate IP," and this one came up and had a creation date that matched when the firmware came out. My problem is unrelated to static IP and DHCP IP reserving, as I believe it to be purely a firmware bug.
