They don’t contain user-identifiable information, and usually they aren’t even visible outside of your local network.
Should I use default MAC address?
Some ISP’s lock down connections to the first MAC that they see, so you’d probably be best off with “Use Default”. If it doesn’t connect after that, power cycle the modem and you should be good to go. Moreover, using a non-default MAC address often disables hardware acceleration.
