“Device not connected IP address being used by another device (172.16.6.2)

Sporadic IP address conflicts prohibiting Apple devices from connecting to Norton Core WiFi.  Three different times with three different devices (MacBook Pro, MacBook Air, iPhone 6s)  Norton Core reboot forcing new IP address assignments so far only temporary solution.  Apple message on computers is “Device not connected  IP address being used by another device  (172.16.6.2)" (paraphrased)  and iPhone just keeps cycling to Norton Core WiFi shows site checked but also shows no internet connection. Seems each conflict deals with IP address 172.16.6.2.   and there are no addresses reserved for any devices.  I have 25 different devices 15 connected and 10 not connected at this time.

Hello richris1 Are you using "IP address reservation" for your devices? If not you should to assign a static IP for each device so that it doesn't change. Here is how: https://support.norton.com/sp/en/us/home/current/solutions/v118380605_core_en_us

Re: “Device not connected IP address being used by another device (172.16.6.2)

I'm having the same issue with Apple devices that seems to have started in the last couple of days, that is this is a NEW issue.  I have a laptop, Xbox, and Google Chromecasts that are connected to the router with no issue, but now when I try to connect with eith my wife's or my iPhone or iPad I can "connect" to the wireless network but I cannot access any websites or refresh apps.  I can't even connect to the Norton Core App to manage the router unless I switch my iPhone back over to data only!

DNS is set up to ISP and I removed any time limits, App version 1.27, Firmware 171218_223.

I will try the suggested "IP address reservation" and report back. 

Any other ideas?

Re: “Device not connected IP address being used by another device (172.16.6.2)

Thanks for your suggestion.  I was trying to avoid that solution if possible since I have 25 devices in my system.  It seems like a work around the issue to me since this doesn't happen with devices other than Apple products.  So I am asking Norton to get it right.  I never had this issue with any other router or router extender combinations, which all have been removed from the system or wifi deactivated.  So I am thinking that this is not so hard to do....it is such a basic function of any router to assign IP addresses without conflicts.  Just for the record, I have no addresses reserved on Norton Core or Static IP address on my devices.  I think the core should work better than it is.

Check each device one at a time and see which device(s) show the IP that is conflicting. Remove one or both of them and reconnect the device you need on the network. Also, set different passwords for your 2.4 and 5.0 networks. That will prevent conflicts as well.

Re: “Device not connected IP address being used by another device (172.16.6.2)

Hello again richris 1 It sounds as though a device previously connected dropped off the devices listing and Core resolved itself. If you are confident its resolved please mark the thread as solved. Just mark the post that provided that as applicable. We are here as always if you need further assistance.

@SMCreasy Change your DNS setting to ISP and let the Core reboot. Recheck your connectivity.

Cheers

Re: “Device not connected IP address being used by another device (172.16.6.2)

Issue reoccurred twice in the past 3 days.  IP address conflict confined to 172.16.xx.x router domain which means that this is a Norton Core issue that has not been resolved yet.  temp fix is to restart the system so that all the IP addresses are refreshed.  not right yet.

Re: “Device not connected IP address being used by another device (172.16.6.2)

I decided to give up on the idea that the Norton Core would perform flawlessly with the Apple products in my system.  I have decided to set up address reservations for the 20 or so devices I have in my system and so far after prior daily issues, the address reservation WORK AROUND does in fact seem to resolve the multiple errors reported as IP Address Conflicts...

So problem not resolved,  work around effective, mystery continues but now remains in the rear mirror of my cyberspace adventures.  Thanks all for your assistance.  You were very helpful.
