How to check your PC's Mac address

Please Note: This article relates to both the TM2 and TM3 versions of the desktop software.

Check Mac Address

This guide will show you how to Check the Mac Address on a PC.

If a user is complaining of an issue where they get kicked out of TM2/TM3 after only being logged in for a couple of minutes there may be an issue with a Mac Address.


6to4 Adapter

90% of the time the MAC address causing the issues will be the 6to4 adapter.

If this is the case running the TestMACAddress exe will contain a  lot of 0's.

e.g 000000000000000000000000E0 as shown below.


Disable The Adapter

This adapter is not needed for TM2/TM3 to function as the 6to4 adapter is a component used for transmitting IPv6 packets through IPv4 network correctly

To disable the 6to4 adapter – open command prompt and enter the following line:

Netsh interface ipv6 6to4 set state disabled.
