Question

Why would duplicate addresses on the router have different mac addresses

Answer 1

You may have a router capable of managing two internet connections.

A mac address is a hardware ID, an IP address is a software ID.

IP's can be changed, mac's cannot.

Answer 2

because two computer were set manually for a static IP

instead of being set to automatically obtain IP

on both machines

start > right click on Internet icon >go to properties>connections>lan settings set to automatic

then control panel>network connections>right click properties>>>in the center window scroll down to see Internet Protocol {TCP/IP} double click on it> obtain IP and DNS automatically

If the IP's must be static then find the two and change the last digit of ones' IP

i.e.: if both are 192.168.0.4 change one to192.168.0.5

good luck

after you are done it would be wise to Start>run>cmd tye ipconfig /release <enter> ipconfig /renew <enter>

Answer 3

Maybe two devices on your network have the same IP address?

Answer 4

If you have a machine with a static IP, it could be causing this conflict when it comes on the network and another machine already has its IP.

Answer 5

Mac addresses can't be shared so even though the address is the same it has to be treated as 2 different one to avoid conflicts.
