Assuming that all you need is the MAC address. Connect your PC to one of the network ports. Ping the router and check your ARP tables or use a lan scanner which shows MAC addresses. From there you can derive the first MAC address of your router and consequently the default password.

Try this command "arp -a" at the command line. That should give a list of ip addresses and their corresponding MAC addresses. Your router should be one of them.

Here's an example output from my Mac.


The router is 10.0.1.1 and corresponding MAC address is d4:ca:6d:30:3c:35. which is the MAC address for ethernet port 2. The password is probably based on the MAC address of ethernet port 1 so you just minus one which will give you d4:ca:6d:30:3c:34.

Hopefully that works.

Wifi will work also. the MAC address of the router is unique. So you change router, it will have a different MAC. Maybe the password was changed to something else and is no longer the default.
