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.
> [...] when I look at the Advanced tab I see duplicate IP addresses:
_Where_ are you looking? An "Attached Devices" report, or some other
thing/place? What's there other than the duplicate-address devices?
Does the problem persist after shutting down all the devices and
restarting them? Are all the client devices configured to use DHCP?
I launch that Netgear Genie and then click on the Attached Devices tab. It shows 7 devices...one wired (my PC) and six wireless. Two of the devices have the same name of EPSON72BA97 with an IP address of 192.168.1.5. One of those is my phone, the other my Epson printer. As I stated before, the MAC addresses are different and I know which is my phone when I look at it's MAC address. Sooo....if I turn my printer off and do a refresh my phone still shows the Epson name and IP address. Then if I turn my printer back on and do a refresh I get the EPSON72BA97 and 192.168.1.5 for both. I also get the same results if I turn them both off and back on separately after doing refreshes of the Genie program. It never ever recognizes my phone as a Galaxy S6. It does recognize my wife's phone as a Galaxy S3. I think I've done all I can...perhaps a Netgear technician can figure it out. Weird.

Did you shut down _all_ the devices, including the router, and
restart them?> [...] Are all the client devices configured to use DHCP?
Still wondering.
Well...what I did was configure my printer manually to a different IP address. 192.168.1.10 rather than 192.168.1.5. So now the printer is 10, the phone 5 and all appears to be fine.

router grants the ".10" address to some other device which uses DHCP.
There was a reason for asking the following question (repeatedly):> > [...] Are all the client devices configured to use DHCP?

> Still wondering.If you assign a static IP address to a device like your (unspecified)
"my printer", but that address is still in the DHCP pool on the router,
then the router will be perfectly happy to grant that address to some
other device, causing the same problem again.
If, for some/any reason, you want a fixed IP address for your
(unspecified) "my printer", then you might have less trouble if you
configure it to use DHCP (probably its default mode), and then reserve
the desired (dynamic) address on the router.Visit http://netgear.com/support , put in your model number, and look
for Documentation. Get the User Manual. Read. Look for "Address
Reservation".If, for some/any reason, you insist on configuring your (unspecified)
"my printer" with a static IP address, then it should be an address
which is _not_ in the DHCP address pool. For example, on these routers,
the default DHCP pool range is typically ".2" - ".254". That is, the
whole usable address range, except for the router itself (".1"). If you
shrank that to, say, ".100" - ".254", the you could use the range ".2" -
".99" for static addresses, and there would be no chance of the DHCP
server in the router granting any of those non-pool addresses to any
DHCP client device. (Barring router firmware bugs, of course.)
For the how-to on changing the DHCP pool address range, look for "Use
Router as DHCP Server" in the User Manual.
