this issue is over my head, i've partially identified the problem coming from the Main RT-AC3200 router.
The main router RT-AC3200 is behind ATT gigabit router, setup as DMZ Plus mode. i have a second router tmobile variant rt-ac68u wired to the 1st setup as Access point, there is a 16 port trendnet switch in between no special features. The second router is seeing 2 gateway ip with 2 different mac addresses. Mac address ending with D7:20 is the correct one see screen capture below.
this is what the client view lists looks like from the tmobile RT-AC68u, both are on wired interface
I don't know where the 2nd mac is coming from, nor have I been successful at blocking it. Windows 10 WIFI connection results with DNS issues, it obtains the mac address ending with E5:F6 which is not correct, i can see this with arp -a at command prompt. google chrome results with DNS_PROBE_FINISHED_NO_INTERNET, until I clear the arp arp -d 192.168.0.1 then statically set arp -s 10:7b:44:c2:d7:20, until next windows reboot or next wifi disconnect and reconnect.
I tried turning off the rt-ac68u and tried to connect to the RT-AC3200 still got the bad mac address.
I tried removing all wiring except ATT gigabit router from the RT-AC3200, still no luck, I may have forgotten to reboot the main router.
i have another ASUS RT-AC68u that shows 2 clients on one row with client ip 192.168.0.1 and correct mac address 10:7b:44:c2:d7:20, i have seen this router also come up with 2 mac addresses on 192.168.0.1, then the client list quickly clears and shows only 1 at the end. This router also is wired as Access point to the same switch the 1st RT-AC68U is connected, and the switch also connected to all the remaining network jacks in the house, the 16 port trendnet switch eventually connects to the RT-AC3200.
I don't know if the switch in between the RT-AC3200 and RT-AC68u would cause issues.
I don't own a TP-link device, haven't been able to block the mac address E8E:27:C6:E5:F6 yet. any help or explanation of 2 clients sharing same ip would be appreciated.
Thanks
